I have two JMCK holsters. Both are quality holsters, but neither quite hit the spot on my body type. I recently made a tweak, and it’s made a huge difference. My 92 Compact disappears now, and I even did a mock-up Centurion, and I think I could pull off the full size grip now.
The holster is the AIWB 2.5 and the mod I did was use a single INCOG belt clip. The INCOG clip drops the gun about 1/4 lower, or more, than any of my stock attachments (clip, soft and hard loops) and allows the gun to rock slightly.
