I just ordered a holster from;

I have a holster for my Glock 33 from Comfort Tuk but they don't make one for our R51's. What I liked about it was the leather separating you from the holster & gun is complete cover. I'm not one for wearing two shirts generally speaking and surely not in the warmer months. But I also don't want the cold gun on my skin nor do I want to sweat on the gun. This AlienGear holster accomplishes both. And if it is as comfortable as the Comfort Tuk I'll be elated. The Comfort Tuk is so good that car, couch, etc. at times I'd forget I was carrying, that good! Gonna check out the Utilclip also;
