I’ve got a couple...Ruger LCP II in .22lr and a NAA bugout in .22 wmr. I bought the Ruger from my neighbor and it was kind of jammy at first, I had the best luck with some high velocity 40gr Armscor. After shooting it a bit it runs a lot better, I was running 36gr bulk box through it a couple weeks ago with no cycling problems. My brother suggested graphite lube, especially around the feed ramp and that did seem to improve things. The trigger is surprisingly nice IMO, so much nicer than the original LCP. The NAA was an impulse purchase from too much armslist over this last snowstorm, I kind of like it though. Fun in its own way. About the size of a set of car keys.
