Rich, I like them because I shoot with thumb on top of saftey "high thumb". My father taught me to keep thumb on top many moons ago. Schools like Gunsite INSIST you shoot that way. For me it's a lot more natural "eaiser" with a lower saftey. Tony is correct some holster's with shirt guard, sweat shields present a problem on reholster. I use a Sparks Summer Special 2 and had to trim the shield a little and have restiched to insure full reholster 100% of the time. What happens is tip of saftey will hang up on shield and will keep weapon from seating last 1/2".
