Another vote for the SR22. I have one for myself, one for my wife, and two others for students. Different vintages: two from Prescott and two from NC. Between them, well over 20,000 rounds in last 10 years. Not yet a single hiccup. I shoot mainly 40 grain standard velocity (used to be green box Remington, now CCI Target), which is what I buy in quantity. However, over time I'm pretty sure I've fired just about every different ammo there is. As stated, nary a hiccup.
If there is any downside, it is the plastic sights. But there are plinkers, not bullseye guns. And so far, all of the sights have survived.
