I presently have a Glock 17. This weekend I went and shot a few rounds being it was a slow weekend. I had been kind of looking around, and reading here on this site about different models of Glocks. I was considering the 10mm, but the ammo seems like it is very limited, and expensive. There have been a few threads on here about the Glock 30, the 45acp. So while I was at the range, I was talking to the owner about the G30, and he said he had a range gun that I could rent and try out, so that is what I did, bad mistake! I ended up putting 100 rounds through it, and LOVED IT! If this gun has any more recoil than my G17, it is not by very much. My shot pattern with the G30 was better than I was getting with my G17 for some reason. The G30 just felt, right, and felt perfect in my hands. Well long story short, when I left the range, I walked out carrying my new Glock 30. Both the Glock 17 and 30 will have the Crimson Trace Laser grips added. My wife has already claimed the G17. I plan on taking my CCW test with it, and this will be my carry weapon. What a very nice gun this is.
