I have a Sig P320 X-Carry w/ suppressor height sights, RDS, and TLR-7A. This holster was the only holster that I could find that accommodated all of the attachments for my weapon...not to mention that I am a left handed shooter as well. When I was shopping, customer service answered all my questions quickly. It was such a great shopping experience. Plus, they shipped it to me in less than 3 days as well. I am very happy with my holster!
