Hi guys.... I recently decided the accuracy issues with my carry pistol were not a problem with the pistol, but that the pistol was too small for my hand. I decided to sell it, and got a Tristar P100. When I sold my other pistol, I had to carry something till it arrived. That was my SAR B6P full size. I was surprised to find it fit the holster I had been carrying my pocket gun in remarkably well! The P100 also fits nicely, and rides very comfortably in the small of the back (actually more like 5 O'Clock). The holster is the Ace Case Tuckable IWB (medium)
https://acecase.com/tuck-able-holster-leather-ambidextrous-fitall-medium.html. The angle is perfect for SOB carry. One serious advantage is that it is ambidextrous. I can carry SOB, strong side or cross draw, all with one holster. Another advantage is... it doesn't break the bank. I have carried it for almost 2 years, daily, and it has held up well. After carrying 3 guns in this holster, one a full size CZ clone, and another a compact CZ clone, I have never had an issue with the gun riding up out of the holster. With a good pistol belt snugged up, it rides low enough that retention is not an issue either. My only complaint was the belt clip system. It is stitched to the lower third of the holster. If you have to drop trou, this makes the holster unmanageable, but I fixed it by gluing the tab the full length of the holster with Weldwood Contact cement; works great. Works so well, I even use the holster OWB for casual carry around the house.
