Lessons Learned

Holster carefully and, if at all possible, slowly. Back in the ’70s I figured out if my thumb was on the hammer when the gun was holstered, it would hold down the hammer of a double-action handgun so it couldn’t rise or fall, or hold back the hammer of a cocked and (maybe, maybe not) locked single-action auto. I depicted the technique in my early 1980s book StressFire. A lot of people caught on, though some didn’t.

The late, great Todd Louis Green adopted this procedure and did much to promote it with a striker-fired pistol having no external hammer. On the Springfield XD with its grip safety, it will lock and prevent a shot when the web of the hand comes off it, thanks to the thumb on the back. Todd and his colleague Tom Brown came up with the Striker Control Device from Tau Development Group replacing the back-plate on a GLOCK, preventing the gun from firing as long as pressure is being applied by the thumb at the rear of the slide.
