I started carrying pistols when I was 19 back in 1993. Glocks, Sigs, HKs, Colts and even some cheap throwaway crap. Most of the time I carried two Glock 17s. Luckily that was my carry the few times I needed them and that cemented them pretty well for me. Back in 2001 I decided to try .40 S&W and grabbed a Steyr M40. I carried that exclusively for a number of years until I went back to a Glock 17. I also have a Kahr CW380 for discreet carry where I can't afford to have someone notice the Glock on my hip. Maybe one day I will be able to carry appendix and do better, but there is no room for that 17 in the front once I sit down. I'm honestly thinking of going back to carrying two Glock 17s with me in the future, maybe I can even pull off some 34s like @moostapha. I think 17Ls are a pipe dream, but would be fun.
