Every week at least one night using the laser glock below. I ripped out the innards of the airsoft 26 pictured, glued a laser to the barrel of it, then snaked the pressure switch under the trigger (no wires on the outside.) Added a floor plate with lead to make the gun fell more like it's loaded. Fits my Glock holsters. I were full street concealment.
Using the laser gun one can turn the lights out and practice against lamp shades, light switches, vases, oh... just about anything that has a silhouette. I even use 'Bob' my punching bag dummy in the garage.
Then I go the gun range with the real glock (a 26 for practice, my carry version is the 27.)
And people wonder why I look so good on the range. Now you know.
