I have a Lasermax internal guide rod laser for a Springfield Armory XD-45 Service (4" barrel). Part number: LMS-4XD45-ACP.
I haven't used it much so the batteries are still good and the laser works perfectly. The recoil spring probably has 300 rounds on it. Asking price is $150.00 SHIPPED. I've lost the original packaging but still have the user's manual.
