I've got a G17, a G19, and the SR1911CMD as of yesterday - and I'm already thinking about selling the G17 to pick up an Officers-size compact Armscor/RIA 1911 to tinker with.
Heck, I would. If your hands aren't so large the G19 feels too small, there's almost no point having both the G17 and G19 unless you like collecting Glocks. (I'm biased: I like the size of the G19 more, so take that as you will!)
I will probably get myself a G17 in the future (maybe), but probably not before I get a Glock chambered for .45ACP.
Given your comments, I'm starting to wonder if one can't have too many 1911s... ;)
Very true. I think a lot of the appreciation I have for the 1911 comes from its history. I learned to shoot with a 9mm, but honestly the "adjustment" people talk about to a .40 or .45 is negligible. I will say that when I have all the pieces laid out, I do like looking at the Glock (23) on the table a bit more.
