The Lasermax LMS-392C is a set of 1.5 volt silver oxide replacement batteries specifically designed for guide rod lasers. They perfectly fit a variety of Glock models such as Glock 17, 19, 20, 21, 22, 23, and 31; their compatibility is determined by serial numbers prefix that include AA, AAA, B, BB, BBB, E, and GGG.
These batteries are also compatible with Sig laser systems that have serial number prefixes CC, D, DD, and Q. If you own a S&W Sigma 1240/1241 with a serial number prefix "AA" or 3" sub-compact, 4" .45 ACP, you will find these batteries to be a suitable fit as well.
They are also a great option for 1911 full size Government models with serial number prefix CF. An impressive feature of these batteries is their approximate 5 year shelf life, ensuring a long-lasting energy solution for your laser systems.
