Have read that Promoted Pawn will (or used to) install an internal laser module in the PS90. Does anyone have any info about whether they are still doing it and how much it costs? Also would like to know what the specs are on the laser module. I have read that the Laserex one that was used in P90 was 8 mw. If that is correct the specs re. dimensions of module are important since I may install a slightly more powerful green module with a focusable lens so I can flare the beam a bit.
