22/45 Too Picky on Ammo

[Smitty79]

I have a 22/45 that I use occasionally for steel matches. The only internal work I've done on it is to put in a Tandemcross bushing to get rid of the magazine disconnect. It fails to fire about 1 in 5 on Wolf Match and Aguila ammo. It fails to fire about 1 in 10 for Federal ammo of various labels. It has been 100% on CCI Mini Mags. Good luck finding those.

Is there something I can do with it to make it light off the rounds more reliably? If it was a centerfire pistol, I would just change springs or put in an extended firing pin.

Have you checked to make sure the firing pin spring isn't broken in half?

That is not usual. Those usually run close to 100% or at least the 5 or 6 Ive owned and the 20 or so friends of mine have. I would call Ruger. They are great about fixing stuff quickly.

Try cleaning the chamber really well. If it persists then try a volquartsen firing pin. If the gun is set up correctly then you shouldnt have all the misfires with wolf.

I put in the Volquartsen firing pin. Wolf ran 100%. One batch of Federal also ran fine. Aquila and a lower grade of Federal had an FTF per magazine. All of the FTFs have a clear strike on the rim. I cleaned it pretty well when I put the VQ pin in. I tried to put in a VQ extractor, but the stock one didn't want to come out even with the plunger pulled out. All the YouTube videos in the world didn't cut it.

I am thinking of looking for a stronger main spring, or at least taking the housing appart and cleaning and lubing what's in there. It doesn't look like it's meant for maintenance.
