My 22A was a little picky, but lucky for me it liked the cheap stuff. The Federal bricks seemed to work well. The firing pin struck with enough force that I didn't have too many problems with them. The Remington Golden Bullet bricks that I normally use for my Advantage Arms kit would be split open by the 22A and burn my hands a bit.
And I predict you'll enjoy cleaning the GLOCK much more than the S&W.
Well both guns fired just fine the 22a had a few bad rounds (primer I think) the glock had three hundred rounds through it and had no jams, misfeeds, bad primers, stovepipes, or well... any problems. And yes I enjoy cleaning the M17 much more than the 22a. not to disapoint but I had only one beer and didn't finish it (bud light sucks, miller lite good:supergrin and just to let everyone know there was a 13 hour gap between beer and guns as the two do not mix well.
