Threads like this make me feel weird.
Before I got into gun-buying, I already knew what kinds of guns I wanted to buy. I wasn't even in a restricitve state. I shouldn't assume everyone is like me, I guess, but it still feels like if you're interested in becoming a gun owner in MA and you're willing to jump through all those hoops, you probably did it for a reason. Was that reason not "because I wanted a specific kind of gun?"
Beats me. But then, I learned to shoot in the military so I skipped the whole .22LR stage of gun ownership, I guess. OP, if you've already decided you want a striker-fired plastic pistol, then buy whichever one fits your budget. Then, as you gain experience and money, do what the rest of us do when we want to try something out: buy it off a fellow NESer, decide whether it's for you, then pass it on to another NESer when it's time, sooner or later.
Good luck in your search.
