“Slightly smaller version of my XD-M Elite 5.25". With a very slight (non-permanent) modification, the slide will NOT lock back on an empty magazine for great dry practice. No BB ammo, just CO2 and not having to reset the trigger/slide after every trigger press changes things a lot! Looks real, feels real - DO NOT take this out where it doesn't need to be... Oh - The non-permanent mod - A piece of Q-tip shaft about a half-inch long placed against the follower between the follower thumb grip and the top...”
