How to Disassemble a Walther P22

Disassembled Walther P22

Introduction & Disclaimer

Firearms are deadly weapons. Improperly disassembling a firearm can result in damage that may cause the firearm to malfunction causing serious injury or death. This tutorial is meant for informational purposes only. By viewing this content you acknowledge that there are no warranties whatsoever to the accuracy of this information. It is strongly suggested that you take your firearm to a licensed gunsmith for servicing.

The following information illustrates how to disassemble a Walther P22. I tried to err on the side of too much information rather than not enough. You'll notice that the slide lever release "j" spring isn't pictured anywhere, and that's because I didn't have a nice step-by-step guide the first time I disassembled my P22 and I lost it. Luckily, the pistol functions just fine without it.

The pistol used in this information has not had the necessary modifications yet, so you'll notice some pretty bad knocks in the slide. It also just come off of the range, so it's pretty dirty.

The number that corresponds to Smith & Wesson's Walther P22 manual is listed in parentheses after each part.

Tips before getting started


Ensure pistol is not loaded

Before you get started taking breaking your pistol down, give it a thorough check to make sure that it's not loaded. Drop the magazine, lock the slide back and check the chamber and action for rounds. To be extra careful, I also remove all ammunition from the vicinity of my work area and put it in a drawer or cabinet where it's sure to stay secure.

Remove the slide

Remove the action

Spring Warning:
Be careful not to lose slide stop spring(16) that sits just under the lever. Once you remove the action there's nothing to hold the lever on anymore and it will fall off. Under the lever is a small srping that has a tendecy to go flying. Some people like to put the pistol in a Ziplock bag before removing the action to ensure the spring doesn't get lost.

This is the point at which to stop for cleaning the pistol. The action is exposed and there's not much that you can't get to with a good can of polymer-safe spray solvent.

Separate the slideplates

Separate the slideplate (left half (2), right half (3)). This is where stuff can get lost if you're not careful. Take a look at this entire section before you do anything so you see that there are two spring and one part that can potentially get lost if you're not careful.

Remove the trigger assembly

Remove the hammer assembly

Remove the barrel

Remove the breech

Remove the safety

Disassemble the receiver

Disassemble the magazine

thank you for such detailed break down. i came in possesion off a p22 in peices and missing peices and you have the best break down i have found so far

Hi, I have a Walther PK380 and loveit. I have ordered thru my gun dealer a P22 for plinking. Mine will have the nichel plated slide and the price seems a little high at $400.OO out the door. My PK380 only cost $340.00 out the door. My PK380 is very easy to break down and clean. Your disassembly info on the P22 seems difficult. Is it necessary to break this weapon completely down to simply clean it? Does this weapon have a plastic key to turn anti clockwise to break it down or do you just use the take down blocks? Will the barrel lift out of the slide like the PK380 held only by the rod and spring? My P22 will be here in about 2 weeks and itlooks very much like my PK380 and I assume the manuel will address the disassemby for cleaning.Just trying to get a head start on it. Thanks for anything you can tell me.

Hi David,

This page illustrates the steps to completely disassemble a Walther P22. There's no need to get this crazy if you're just going to clean the pistol. There's a note in the page above about where to stop taking things apart if you're just cleaning the pistol.

The P22 has a fixed barrel that screws directly into the front of the chamber. It's not a float barrel as is typically found with higher caliber handguns.

I hope this helps. Remember to use the recommended types of ammunition with your P22 and you'll have a blast (no pun intended).

I just got my son a p22. after our first visit to the range I went to break down the gun for cleaning but can't seem to Pull down the takedown lever. What am I missing?

On April 25, 2010 Ben said:

Hi Bart,

The lever can be a little stubborn. Use your fingernail to gently pry/pull the top of each side of the lever away from from the frame of the pistol as you're pulling it down. There are two little clips at the top that are tough at first. Pulling them away form the frame will allow the lever to slide easily.

Help! After reassembling my P22 the trigger will not cock the hammer. I have gone thru the steps multiple times with the same result. The pistol looks to be assembled like it is suppose to in the picture but I can't get it to work. Any ideas on what I may be doing wrong?

On June 3, 2010 Ben said:

Hi Ricky,

Is an empty magazine inserted when you're pulling the trigger?

On July 4, 2010 Tom said:

Like Ricky who posted on June 2 I too just reassembled my P22. Had to remove the trigger bar and smooth out the ears so they weren't gouging my slide anymore. When I reassembled the firearm it would only work as a single action. I can shake the gun and bump it and sometimes the double action will catch. I thought I had something in wrong so disassembled again and reassembled. Cannot find what I am doing wrong. Worked fine when I initially took it apart. Please advise. Thank you!

have a walther p22 in a box with all the pieces i think. do you have a series of instructions that will show me how to identify and install each part so that i can put it all back together again?? got it for a steal, hope all the parts are here so i can put it together and have a neat little 22 for plinking. can use most of the drawings above but need help on the hammer assembly, sear and such so the hammer will work correctly. thanks, i can pay you a little for your help if needed.

On August 5, 2010 Ben said:

Hi gene,

There's some close-up images of the hammer/sear in the content above. Can you follow the steps in reverse to put the assembly back together?

On August 7, 2010 Bill said:

Excellent step-by-step!

I just used it to fix a friend's p22 that the PD Evidence monkeys broke. I'm not sure how they got the internal lock so jammed, but your attention do detail allowed me to get to the problem. :-)

On August 8, 2010 Max said:

I too reassembled my walther p22 after replacing the hammer spring and it now only works in single action. can pull the hammer back and it locks all the way down with my thumb but when i slide the action all the way it will not keep the hammer back! please help!!!!

On August 9, 2010 Jess said:

A question & a comment...
How do you remove & replace the rear sight on a P22? Please email me with instructions if possible - I'd like to replace it with a higher, elev. adj. (maybe Fiber or tritium).

Comment-I replaced my front sight with a HiViz Glock Fiber Optic front w/interchangeable light pipes - works GREAT!

On August 25, 2010 STEVE said:

my p22 will not fire I am getting a very light mark on the rim of the 22 shell. I think maybe the firing pin is broke or damaged. Would anything else cause the weapon not to fire. If it is the firing pin how do I replace it. Thanks Steve

On August 26, 2010 Ben said:

Hi Steve,

The firing pin in the P22 is a solid piece of metal. There's not much that can go wrong with it (check out the images above that talk about removing the breech, and you'll see what I mean).

It sounds like your firing pin spring needs to be replaced. Do you dry-fire the pistol often? The P22 has an inertial firing pin that seated by a small spring. When it's dry-fired too much the spring no longer returns the firing pin to fully to the rear of the breech. This added space between the pin and the hammer cause weak cartridge strikes.

Go ahead and take your P22 to a local gunsmith and let them know what's going on. Chances are good that it will be back to normal with a new firing pin spring.

On September 22, 2010 Ron said:

Definitely better than the manual. I won't go farther than the slide, but I used this as a general idea for my PK380 when I couldn't find anything good on that. Thinking about getting the 22, but read somewhere the slides are cheap.

On October 23, 2010 Santiago said:

hi i was wondering if the dowel pin that holds the breech is firmly secured? because im having a hard time tapping it out it wont give... thanks

On November 13, 2010 Rudy said:

Purchased a P22 for my 10 year old and he loved it.
When we cleaned it, we only dissembled it only to the point of removing the slide and spring guide.
Took it back to the range the next weekend and it wouldn't fire. I then noticed that it can dry fire even when the safety is on. Is this normal? Is this a signal that I re-assemble it wrong and thus itís not firing?

Appreciate the feedback.

This was so much more helpful than the hand book that came with my pistol. Thank you

On February 26, 2011 Tec said: Concerning "On April 25, 2010 Bart said" I also had a problem with the takedown lever. When I found this page and looked at the first photo I noticed the slide was locked to the back to begin the disassembly process. I did that and and the takedown lever pulled down easy. This wasn't in the instruction book Walther included with the pistol. I just got mine yesterday. Hope it helps.

Just purchased my P-22 and getting ready to break it in. A little help with which parts should be cleaned and oiled after each firing session would be of benefit. The manual states to clean barrel with oil soaked brush (?). I am using Hoppe system and their products and following their recommendations. Not sure if this is best system and would appreciate comments from others re methods/products. Thanks - love your website.

Hello, i recently bought a p22. After putting about 300 rounds through it the internal saftey pin that you need a special tool to operate from safe to fire mode simply fell out. I dissasembled the firearm and figured out it was just a tiny spring that broke.Replaced it now i am faced with a new problem, it only works in single action. The gun fires no problem as a single action. However i really would like to have it back to normal. Looked through your step by step dissasembly here and everything looks fine. There are no parts missing and seems to be in proper order. I see other people have had this same problem but i dont see any solutions posted. Does anyone have any suggestions? Would like to avoid taking it to a gun smith.

On May 28, 2011 Adam said:

To fix the single action only problem, take ur gun back apart and expand or stretch your magazine safety spring, along with your trigger bar spring. These parts become compressed and dont allow the trigger bar to return fully. Let me know if this helps.

On August 16, 2011 Daryl said:

I have a new P22 and the first time I fired it the empty shell casings were not ejecting all the way out and jaming the new shell. Sometimes when loading the first round the slide going forward does not insert the shell far enough and does not close.

On August 21, 2011 tyler said:

Adam is correct. I had the same single-action problem. The trigger bar spring is not very strong and it can get bent too much if you do not remove it prior to rounding off the trigger bar ears. I bent it back and the the trigger now functions properly in double action. Thanks!

anyone know how to remove the rear sight on the p22? its loose and cant seem to tighten it. email me please. thankyou.

Okay I need help!!! Just purchased 22 with laser at pawn shop didn't come with manual and I was playing with my new toy been many years since I owned pistol more use to shotguns anyways, pressed button and the slide flew off and spring and rod were does the spring and rod go and how do I get it back on

how can i order a new hammer assembly spring. can you give me a web site to order parts from, thanks AL

On February 6, 2012 Alan said:

Thank you for such an indepth breakdown. I am definitely not a gunsmith, and I was able to follow these directions to replace the hammer spring that broke on my P22. I called smith and wesson and sat on hold for 10 minutes, but it was well worth it. I told them what i needed on friday, and today(monday) a package with 2 hammer springs showed up in the mail for free. An hour later i had one installed and reassembled. The only thing i had trouble with was the two safety springs around the trigger. (the trigger lock spring kept falling out of place, and the mag safety spring i struggled a bit getting it to compress to fit under the second plate during reassembly.) The key to this whole thing is taking your time, and dont force ANYTHING. These are precision instruments and if it doesn't fit right the first time take it apart and try again.

Hello, I have a P22 and have taken the slide off for cleaning many times but have often wanted to break it down further but hesitated for fear of ruining something. Your instructions were a huge help and I have successfully taken my P22 down to every piece and put it back together. I have bookmarked this page and subscribed to the news letter. Great work you've done here! Thank You!!

i have broken the hammer spring in my p22 and am finding it impossible to order one. local gun shops are no help. where can i order one from

I have the same question as Rudy, I have a p22 .When we cleaned it, we only dissembled it only to the point of removing the slide and spring guide.
Took it back to the range the next weekend and it wouldn't fire. I then noticed that it can dry fire even when the safety is on. Is this normal? Is this a signal that I re-assemble it wrong and thus itís not firing?

I have a p22 5 inch and my two front screw/bolts at front of gun are about done? I want to know where I can get replacements for these two? also what is the type of tool specific is to remove these? I got the gun used and need to replace old parts. So slightly stripped but I believe I can remove if I can get new ones. I cant find them anywhere please help?
Thanks Jesse

Wow, if it wasn't for this guide, my not-so-beloved P22Q would nothing but a pile of metal and plastic parts. Thanks.
Protip: Yes, the weapon will dry fire even on "Safe". The safety is nothing more than a crossbar that prevents hammer-to-firing pin contact. I would advise against dry firing on "Safe" as much as I would on "Fire" to prevent damaging the firing pin or safety bar.
Protip 2: I never liked the magazine disconnect safety feature, so I took the opportunity to disable it by leaving the magazine safety springs (24,34) out during reassembly. Not only does it get rid of that annoying feature, in my case it actually softens up DA/SA pull and the magazines seem to catch and detach with less difficulty. YMMV.

Anyways, thanks again for this guide, I am bookmarking it just in case I ever get lost again. Happy shooting!

How do you replace the takedown lever? S&W sent me a free replacement, because the plastic wore away on the edges and it wouldn't hold the slide down anymore, but I can't find instructions on how to free the lever to replace it.
