Some of you here know that I'm a SIG guy. I've only ever bought SIGs, but I got a wild hair last month and decided to try out a glock. I got a Gen 4 17, since I had done well with my dad's gen 3s. With the medium backstrap, I was getting slide bite like you would not believe. So I put on the medium beavertail strap. Whew doggie. That's niiiiice. Now when I pick up my 226, it feels HUGE. So I'm gonna work with the glock this next year until I get the proficiency I had with the comparable 226.
