Misfires with sp22m3

redriderxxx · 06-07-2010, 10:25 AM

I could use a little direction. I have a sp22m3, it is wonderfully accurate but I continue to have misfires with all kinds of ammo. I've tried just about anything I can think of and without fail, I always have misfires. About the best the pistol will do is 1 out of 15, sometimes it is worse. Wolf Match extra for example will misfire 2 or 3 times out of 10. CCI standard velocity and RWS rifle match were 1 out of 15.
I have cleaned the chamber, cleaned the bolt and even oiled the firing pin. Everything else seems to be as it should. This doesn't seem to be a wide spread problem and the gunsmith I see when I can't figure something out seems stumped as well.
It appears to be going fully into battery but don't really know how to test this theory. Anybody have any ideas?
Thank you, RR

Yes, they look pretty much like the strikes on a fired case. I can't see a difference. I don't think it's the ammo, it shoots fine in my custom 10/22.

Are you absolutely certain all the FP indents are just as deep as those made by your 1022?

Are some slightly shallower?

Do they always fire reliably the second try in another gun?

I guess I can be a little hard headed, logic would dictate that the firing pin strikes would have to be shallower and though I find it difficult to discern a difference, there must be.
I took the Walther out twice since the post and did not feel it shot any differently the the first time. Brought it home and went through the cleaning, oiling routine. Today I concentrated on giving the cocking knobs a push forward after every shot. There was little if any difference. I still had misfires with the same ammos. I did notice that CCI standard velocity, which was one of the better shooters, shot perfectly, albeit with the cocking knobs given a push. Wolf ME and Winchester Target fared worse. Aguila shot better. Then I shot Federal 711B which I had squirreled away and 20 shots, no push on the cocking knobs, shot flawlessly. Then I loaded the misfires into a mag, there were 8 or 9, and they shot just fine with no assistance. I am not sure what happened, but all of a sudden it seems to work better. I think one more cleaning, oiling and test fire before i jump to another conclusion, but I feel optimistic. Thanks to all that replied.

I've never owned a pisttol with that many letters and numbers in the model #,I'm not even sure what the pistol loks like but with that said if it was brought to My shop , if it is possible to get to the firein' pin I'd be sure it was smooth , look for any burrs or bends, if it runs in a groove or tunnel be sure it has no burrs and is as clean and smooth as possible...it is aggravatein' to clean up , but You might try coatin' the firein' pin with a fine grindin' compound and lappin' it into the groove or tunnel that it runs in.....Said all that to say this , sounds like the firein pin could be bindin'......Maybe try puttin' a fired case in the chamber and dry firein' a lot
