Thanks for all the feedback! It was my understanding that by adding the reinforcement section, it adds rigidity to the ejection port area for retention. While this is my first entry into the holster realm, I was pleased with how they turned out. I recently added a new optic to my Sig, so I'm going to have to make another holster for it. I do plan on correcting the grip clearance. I incorporated a 20-degree cant on these. Is there a better/more comfortable angle I should consider?
