Glock .27! I love this OWB holster as long as I'm wearing a coat, hoodie, or some type of throw over. Other wise I wear it with an Uncle Mikes IWB holster.
This is my G27 next to my bodyguard, the bodyguard is hardly even noticeable and more comfortable to carry. It's smaller, lighter, and slimmer. It's primary use is my back up gun at work but I CC it a lot to.. I try to carry the g27 more often because of its higher fire power. More rounds, higher calibre, and more accurate. Surprisingly I shoot the G27 just as accurate as my 23. I have a +1 grip extension so theres a place to rest my pinky! I couldn't shoot without it!
