I've been eyeing a G26 for a few months now and I finally decided to make the jump. I just picked up a couple of the Pearce grip extensions and I'm glad I did because I wasn't able to get a great hold on it.
I have that trio also, love them. Along with my G21! I love carrying the 26, easy to hide. All my mags have the GAP floorplates and they work well, I don't like the extensions very much.
I heard it said that the Croatian PHP pistol was the result of a P38 and a Beretta getting together in a dark room, but I didn't know that Glocks would do that, too!
