My Glock friends keep telling me that the lack of an actual safety on these pistols can be overcome by “training” – which means learning to keep your finger away from the trigger at all times except for when you want to shoot – and using the proper holster, which covers said trigger so you can’t get a finger in there during a “draw”, or hang it on something else that might pull it. I’d still rather have a manual safety that locks the slide and trigger, but do agree that holsters should be made to fit the pistol they will be carrying. For my G20, I ended up ordering a special Glock holster from Crossbreed, half Kydex, half leather. The Kydex part is molded to a G20, the leather is a backing and secures the holster to a belt.
This arrangement fits the gun like a glove – as it should – and is cut so that it will allow a mini holographic sight like my Burris FastFire III to work just fine when holstered.
Just don’t get in a big hurry when ordering one of these, because Crossbreed builds them one at a time, as they are ordered. For your wait, you get a near perfect holster, at a very fair price.
Go to Crossbreedholsters.com, and look at their Snap Slide series for Glocks 20,21,30, and 30SF.
