Was my first centerfire pistol. Figured, if I hated, I could sell it easily. Turns out I like it a lot. Very easy to take down (especially compared to my wife's 1911-ish guns), fun to shoot. Seems to be just the right size, I can just get my full hand on the grip, takes the G17 and G18 mags. I did change out the sights for night sights. Initially, I thought I liked 3-dot sights, but in the end, at least at the range where it's lit, I don't look at the dots, just line up the tops.
Is this your first Glock?
