That's the nice thing about hammer-fired pistols, and especially bobbed hammer pistols like the LEM models. When you go to holster, just pin your gun hand thumb on the back of the hammer. Holster slowly, deliberately, and look at the holster when re-holstering (every time you have the time and opportunity to do so) to be absolutely sure things are safe. If clothing or something works its way into the trigger guard upon holstering, you will feel the hammer start to move but be able to solidly resist it with your thumb enough to stop what you're doing, pull the gun back up and out, and fix the situation before finishing re-holstering.
