Sold my Glock 42 (laser also fits Glock 43) and now must sell my ArmaLaser TR5. If you've never heard of ArmaLaser they manufacture premium laser sights for concealed carry pistols and are always the top-rated lasers on Amazon reviews. MUCH better activation than Crimson Trace and more reasonably priced too. This is the cream of the crop for self-defense lasers. Paid $108.75 and will take $85, very lightly used and new battery. You'll love this laser, I went past the window to return it.
