There's really only a few choices. Fn510 was interesting but after seeing so many of their frames falling to pieces, I'd stick to glocks. Glock 40 and 20 are cool.
Fuck Smith & Wesson, fuck SIG, fuck 1911s (might be a few good choices but RIA sucks and was my only experience with 10mm 1911s)
I like the CZ platform more than anything so I bought a 10mm tanfoglio.
So in my opinion OP it's glock unless you want to spend a pretty penny and get a tanfoglio. My stock 2 was 1400 on sale. Normally 2100. Going to get a 9mm conversion kit and it'll be my main HD pistol. Glocks have more aftermarket support to basically build anything you want but I like metal frames and hammer fired pistols.
