I own a 19, 27, 30 Glock, and my 19 is a Gen 2. Picked it up used, but good shape for about $400.00. The 19 is real sweet to shoot, and so far very reliable. Also, with two or three 15rd. mags full, you are well prepared.
My favorite though is the Model 30, 45acp. It really shoots nicely. Smooth, accurate too. with 3 10rd mags. you are well prepared too. I have also owned several Kimber 45acp's and they are real nice. I recently went back to a Colt Lightweight Officers ACP. Small and very concealable..And Colt is IMHO the best 1911...
