If I spin the round it will usually fire

A friend of mine has a 1911 .22 and a little walther .22 and no matter what ammo goes in them they always jam or not fire every few times

The recoil spring might be the problem

IF the rim is being dented, the problem MAY be that the gun has been excessively dry fired, dinging up the mouth of the chamber. Check and see if there is a ding. If so DO NOT REMOVE IT- you want a smith to "iron" the metal back in place with a chamber iron.

If the rim is NOT being dented by the firing pin, then you may have a FP problem- chipped, dirty, not lubed.

By "spin" the round, are you saying that the hammer strikes the round once without firing, but by rotating in chamber and hitting it a second time, then it fires?

One of three things, the ammo or the main spring or (as stated above, the .22 was dry-fired and) parts are deformed.

Most semi-auto .22s require a HV round to work properly. Care must be taken on which HV ammo you get. CCI does not recommend Stingers in those that the chamber is not cut to the ANSI specs. And most European .22 are not to American National Standards Institute specs.

I'm using Remington .22 shorts , no dents ding or any dirt after excessive cleaning, and its American made

And all all strike look good

First thing I would do is get different ammo.

[locutus]

The is a common occurence even with quality vest pocket pistols.

That's why so many cops choose the centerfire .25 ACP over the .22 for deep cover back ups.

Thank you I got some Winchester ammo I'm trying in the morning
