If it's not cycling the next round, there's (a) not enough recoil generated from the ammo, or (b) too much friction in the slide to allow it to operate.

Since you've cleaned and checked the gun, my guess is that the ammo is just too light to operate the pistol reliably in its current condition.

If you can make the ammo work, but your daughter can't, you know where the problem lies. If the gun has worked reliably previously with this ammo, then it's pretty much got to be dirty somewhere. Maybe a rigorous cleaning of the slide with gun spray, making sure that you clean the firing pin area, might help?

I've got this pistol and have never had a single function problem except when I tried to use under-powered ammunition.

I'm thinking an ammunition problem also. It's funny though because it ate the Winchester fine before. I gave it a thorough cleaning yesterday but I found that the inside of the magazine had a build-up in it today when I was looking at it. I stripped the magazine and cleaned it out. I don't know if that contributed to the problem or not but it's one less variable.
May take it out today as it's a beautiful day here.

Good luck Joat, and keep us posted

I bought an SR22 for my wife a couple years ago. The only ammo I can recall that it didn't cycle was Blazer. We have since traded it, but the pistol ran good. I did have some problems with Super X in a 10/22 before, but those were mostly dud primers.

Got out yesterday afternoon and tested the pistol. I brought 36 grain Winchester SuperX and CCI 40 grain. The CCI ran with no problems and I had a few, but not as many, problems with the Winchester.
I noticed a few sharp edges on the Ruger that weren't there when it was new and I dulled them down.
Still haven't come to any conclusion as to why it functioned with Winchester then wouldn't but the CCI worked fine.

We have a SR22 and it has been flawless with somewhere over 1000 rounds, it even functions fine, although slowly, with subsonic ammo (bought by mistake, I would not make a regular diet of it).

I got it when it first came out. I'm gonna keep it but I may look into getting another .22 pistol in the future.
