I have seen the internal laser from promoted pawn, but other than that all the other ps90's i see have them mounted on a side rail, i do understand it is a pdwccs (persoanl defesne weapon coke can shooter) yes mine will never point at anything living (zombies are dead technically if they invade) but does someone make a rail or something to mount the laser under the barrel shroud, yes i know the shroud has play, but i figured a few strategically placed metal shim job on the flat part where it meets the frame would take most of it out, that way the laser would still be on target just high and low at the other than zero out posistion, but wouldnt a side mounted laser be way out since it is moving horizontally to the path of the bullet resulting in a complete miss instead of just a high or low hit, has anyone tried one of those multi rail barrel mounts they make for ar-15s that just bolt onto the sleeve so it can be in line with the bore? would that even be feasible, definitley a wescog, but hate coyote'n a purdy lil 90 like that.
