Great add-on so far - Crimson Trace LG-459 Laserguard for Smith & Wesson M&P380EZ

Fits nice to the rail, not so well to the trigger guard though, but it's still an excellent little attachment. The instruction manual indicates it's supposed to be dead on with the factory sight at 50 yards which is pretty funny on a 380ACP. I want it to be dead on at 5 feet myself, if target is 50 yards out I am probably reaching for something else.

Uses a weird battery, but it's very easy to change without removing the laser. The pressure switch is sharp and pointy and not easy to activate but your finger knows it's there in the middle of the night.

There is a master power switch too, very small and tucked into a notch on the side. I hope it's not going to drain the battery if this is left on. I guess if you're going to put in your safe it's nice to use the master switch (or just pull the battery) i am not planning to use the master switch myself as this weapon is always kept within reach and I want the laser as soon as i tighten my hand around the grip
