Lots of awesome suggestions from these guys, OP. I had the same question a couple weeks ago, and ended up buying a M&P 22. I just took it out to the range earlier today, and put approx. 360 rounds through it, an even spread of the following :
-CCI Mini Mags
-Federal "Target Grade Performance" (black and white labelled bulk box of 325 rounds)
-Winchester "333 Rounds" bulk box
The CCI ran flawlessly or without and issues I should say,
The federal stuff had 2 failures to feed the next round,
The Winchester had about 6 or 7 failures to feed as well.
I noticed the latter half of shooting the Winchester bulk didn't have any issues whatsoever.
Just a data point for you to consider from a gun newbie, OP.
Good luck choosing, Mitch
