I have a Raptor for my SIG p320 compact and a Sidecar for my Glock 26.
I obviously carry appendix.
I prefer full sweat guards on my holsters because I live in MS. I am a fat, hairy man. I sweat year round.
The claw definitely works as advertised, at least for the appendix position. It helps with concealment so I'm in favor of it.
I have ordered and am waiting on another Sidecar holster for a Glock 19 with optic on it.
For a point of reference, I am a holster junky. I have spend more money on holsters than I care to admit. I have 4 G-Code INCOG holsters. I don't even know how many Raven Concealment Phantom holsters (I think it is close to 10). I have a Crossbred Supertuck. A Bravo Concealment DOS. And there are some others in there that I know I am missing. Point is, I've tried a lot of things and spared no expense when it comes to holsters. The T-Rex Arms holsters are my current favorite. It is clear that the guys making these use them. They have to be guys that carry every single day. And they carry appendix, which is important to me since that is where I carry.
I've shared this pic in this subforum before but will do so again.
