I started with Sigs and HKs and hated Glocks. One day at a LGS, several guys there had Glocks as their CCW and tell some of their experiences with them. They were able to convince ne to buy my first Glock, a gen 2 19. For fifteen years, I have learn to shoot well with it and trust it.
1. Glock 30SF
2. Glock 23
3. Glock 19
4. Glock 26
5. Glock 23C
I still have the Sigs and HKs for the range.
Glocks are the HD/SD go to guns now.
