I've heard this before so I'll add to the conversation. I started several months ago with my first Glock-a 19. As I've become more comfortable with the gun and groups have become a little tighter, I ran across a good price on a 17, bought it and, this morning, took it to the range. I know it's the shooter, not the gun, but I couldn't hold a candle to the smaller gun. Now, I have to try a 26 and I'm guessing that I'll wind staying with my slow but seemingly steady improvement on the 19.
