Got mine yesterday and immediately took it to the range. I was also in the "Why the hell did they go long frame and short slide as opposed to short frame and large slide?" camp but after 200 rounds down the range I must admit.... this is my favorite Glock to shoot hands down. I am loving the balance of it and the trigger, while still a glock trigger, is noticeably improved. The slide serrations.... meh. I went ahead and put a new set of Night Fision tritium sights on it that I had originally been gifted to use with my G19 and it makes for a sweet look. I am now a fan of Night Fision sights. That is all I am going to do to this gun as it is good to go as is. Fits perfectly in my Stealthgear and Vedder G19 holsters. I also got to lay hands on the new Gen5 G19 MOS and it will be next. Glad I didn't get the G19 at release. No more stupid cut out on the frame and the MOS setup looks nice.
