I recently acquired a Sig Sauer P938 for my EDC, and purchased an Alien Gear Cloak Tuck 3.0 IWB holster to carry it in. Both are great products that I'd recommend to others.
I carry the gun in Condition 1 - cocked and locked. Over the course of two or three weeks, there were four times when I unholstered the weapon at the end of the day only to find the safety was off. After a fair amount of head scratching, I discovered that the Kydex shell of the holster was just loose enough to allow the gun to slide forward and back about 1/2". (Retention was still good when wearing it, but it could slide forward if pushed...like when pushed against a car seat when carrying at 4 o'clock.) Between that bit of movement and the somewhat sticky neoprene backing of the holster, it was enough to grip the safety lever and allow it to be clicked off. I switched to the smallest spacers supplied with the holster and still had forward and back movement.
I fixed the issue easily with a heat gun and a slight remolding of the Kydex at the opening. Now the gun is held firmly front to back, but the draw is still smooth and fast. (As is re-holstering.) I'm sending a note to Alien Gear to let them know what I discovered, but figured I'd share my experience for others here using the same gun and holster combination.
