Well here is the new Glock frame style. Obviously the changes are the grip texture and slide grooves. I gotta say that the grip texture feels rock solid and the scalloped slide serrations and more aggressive feeling than the old style vertical grooves. This is my first personally owned Glock (department uses the 21) and I hope it is as reliable as everyone says. Didn't get a chance to shoot it yet but will set some time aside on Friday and report back. Any Glock owners out there with some advice as far as anything that needs to be changed out or upgraded? I'm thinking the Glock OEM extended slide catch, XS sights and maybe a metal guide rod (plastic!!!..really Glock, Plastic?). Enjoy the pics.
