Question: Will this laser work on the 38 caliber south paw?
Document: Laser works fine. However, for someone who is right handed the laser should be on the thumb side (left). The thumb is lower on the grip and never going to be in the way of someone's big index finger. It's for my wife's revolver and she's fine with it. Me, not so much.
It arrived quickly as usual and fit perfectly. It was easy to install - comes with a fresh battery and good instructions. Easy to sight in. The grip button is located in a very logical place and it does have an off switch if you want to turn the laser off. Would definitely recommend.
I installed my laser grip on a Charter Arms Pitbull .40 S&W. I did have to clearance one section for it to fit properly, but I felt that was a variance in the gun manufacture rather than a flaw in the grip. It took just over four minutes from unboxing the grip until the first time I turned on the laser. I have not been to the range, but it appears accurate according to the iron sights and it is easy to adjust.
Very high quality and well packaged for delivery. Great easy on instructions for attachment and true-up alignment. Total time to get operational and accurately aligned was 20 minutes.
I would recommend the grip to anyone.
I purchased the sights for my wife. It greatly increased her target score. Easy install great product. My order was processed in a timely manner
I have crimson trace on all my pistols for accurate shooting and would recommend to novices in particular. Most effective at night and easy to use.
