I've been looking at concealment holsters with thumb retention straps. I looked at DeSantis holsters, but don't like how the strap impedes my getting a high grip. I've looked at Galco, and for both my XDm 40 3.8, and my XDs 45, I'm looking at the SC2 for IWB, and the Galco Cop3 for OWB Does anyone use either of those holsters (Keep in mind, I'm looking at the SC 2 not just the SC). I've heard that the SC doesn't stay open, but would rather hear from you guys here! Let me know what y'all think!
