This fits Glock 42 43 43x and 48 models. It's not the cheap glow in the dark sights that needs light to recharge. Tritium always glows in the dark, no matter how long they've been in storage. 
I ended up with a red dot and don't need this anymore. Retail $119.99 but yours for $100. 

will trade for ammo in .380 acp, 9mm, .45 acp, .357 magnum, 38 special, .44 magnum, or 500 magnum. 

Will meet in wasilla, Palmer, or chugiak for Jo extra cost. Will drive to Anchorage for $15.
