I've been into Glocks for over 20 years. The main thing I like about them is they're ultra reliable, striker fired, double action only, and high capacity. What I don't like about them is the grip ergonomics. For the longest time I just sucked it up because the competition wasn't much better. Also, once you spent a lot of money on a system it's a drag on making a change.
I'm at the point now where I'm going to experiment with some other pistols to see if I like anything better. I like the grip ergonomics of 1911s, Browning Hi-Power and Browning Buckmark a lot.
Is there a pistol that is ultra reliable, striker fired, double action only, high capacity and with a grip like a Browning Hi-Power? I will probably rent a few M&P 9s to see if I like them any better than my Glock 9s. I have a Shield 9mm but it's just way too thin to get a solid hold onto it.
Maybe one of those rubber add-on grips will be enough.
