I own 5 Serpa CQC holsters. Why? They work. Their retention is awesome. Swipe 1 finger as you go to pull and it is unlocked. I can use them on a standard belt, molle, battle belt, chest right, thigh rig, etc. Just need the proper attachment. Molded plastic makes it safe, secure, protected from bumps and hits and easy to draw and holster as it slides right in and out. It is the ONLY holster I will use if available for my pistol. They do not make one for the Ruger SR9c, only the SR9, but there are videos on YT that show how to cut it down to fit an SR9c perfect (just cut off excess material). Love these holsters.
Pros: light weight, great retention, modular
Cons: not made for every possible gun
