After reading a lot about lasers on pistols, I decided that I wasn't going to die happy...unless I had a Laser on my Kel Tec P-3AT! (Years ago I also had the same feelings regarding a HD Sportster!) Actually, the main reason I wanted a laser was that trying to quickly sight a pistol with bifocals...and hit anything was getting more difficult. However, buying one wasnt easy for me because the dang things are costly. It seems that most P-3AR owners install either the Crimson Trace Co. (CTC) Laser, or the Armalaser Co. Laser. Choosing was difficult because I have read nothing but good reports about both of them. However, from all the information I could find, it appeared the installation of the Crimson laser was simpler. It didn't require any removal of pins, etc. from the body of the P-3AT. That and the smaller looking size of the Crimson laser pushed me in that direction! Two and one-half days after ordering the LG-430 from Shooter's Resource in Oregon, it arrived in my mailbox. Service like that is very hard to find in this day and age! I would like to write that it took me only 30-seconds to install the LG-430, as other people had written.. But, sadly, I can't say that...because I spent 5-minutes or longer trying to stuff the single battery in it's slot...the wrong way! I guess I should have read ALL of the instructions! Well, heck...it really looked like the battery should go that way! :roll_eyes: Once I realized my mistake, it took me only a few seconds to snap the two sides together and install the two tiny little (very tiny) screws. Boy, I'd sure hate to drop one of those babies! The Crimson laser works great! The laser was sighted in at 50-feet by CTC. I found the laser red dot to be right on target (per the P-3ATs fixed sights) where I would need it 10 to 15-feet. The on/off switch for the CTC laser is a small button just below the trigger guard at the front of the grip. For a carry pistol it works just fine. However, I wouldn't want to have one on a target pistol. The free Galco Holster that I received looks very nice and my P-3AT fits in it very nicely. I'm a happy camper!
