I own a few Glocks. Well, sixteen in total. My overall favorite is the G20. The G20 is not only my favorite Glock, but my overall favorite pistol. I own two of them, and a G20C. My next favorite Glock is the G33, and I have two of them. Next up are the G29 (own two) and the G32 (only one), in no particular order. I also own a G26, G17, G19C, G21, G30, G36, G31, and G35 (with aftermarket .357 Sig barrel).
I also own Sigs, Walthers, HK USPs, HK P7s, and a few others. Along with my Glocks, I also enjoy my Sigs and Walthers.
