.22 semi wear and tear q

aacx22 · September 9, 2013, 05:29 PM

I have had an American Arms CX22 for about 20 years. I hadn't been shooting regularly, but lately I've started to take it out and it's misfiring a lot. As far as I can tell, the indentation on the round is placed right... but it's not firing at least 3 out of 5 rounds. Not as often, but it's also periodically not ejecting the shell properly.

I've been able to take it apart with schematics and videos found online... its a pretty simple design, which is cool. I've ordered a new firing spring, presuming that the spring itself is probably worn.

Is there any rule of thumb on how often to change springs on guns like this? It looks pretty easy to swap this part out, but am I missing something, and its a bigger deal than it looks like, and I should get someone who really knows what they are doing to take care of it?

Thanks in advance!

Hello. Keep it clean and lubed.

I suspect that you are on the right track. I have had more than one high-round count .22's that developed that problem. Also, had a High Standard Model B in which the firing pin itself broke that resulted in intermittent firing.

I do not know of anyone who routinely swaps-out firing pin springs...they almost always wait until a problem manifests itself.

Thanks for the replies all.

Maybe I have the wrong gun, but I thought that was a copy of the Walther PP. If so, wouldn't you want to replace the mainspring (hammer spring) rather than the firing pin spring, which serves to retract the firing pin, not drive it.

Thanks for your comment! That definitely makes sense. I'll take a new look at it.

It may actually be easier.

Just a thought - if you have had the gun for 20 years, have you had the ammo that long also? If so, get some fresh ammo (if you can) and see if that helps.

and you might look at the face of the chamber for burr's and or powder ring.
both will keep the firing pin from doing it's job
