So far I have done a few things to my G27. I put on a set of Truglo TFO night sites, a grip plug that I can still use my back straps, Glock extended slide release, Glock magazine extender (3 of them), a tungsten guide rod with a (22lb) spring, I polished the barrel, all the pins, slide release, and take down lever. Took awhile to do it all. I had to do it all by hand. Used a lot of elbow grease. I use 40 S&W Hornady Critical Duty 175 gr with the Flexlock. Share what you have done to make you weapon stand out. Excuse the smudges on it. I had to keep standing it up. Was hard to keep it all the way clean. That's some nasty ammo there.
