Wanted to like it - LaserMax Guide Rod Green Laser Sights for Sig Sauer P226

Purchased the green one fir my P226 , and it installed fairly easily. Had it installed for about a year and fired the gun with it only a few times . The kast time i feild strupped my pistol to ckean it and reassembled it, the laser no worky. It now stays on continuously and wont shut off with fhd switch. I instalked everything correctly. I emailed LaserMax and got response weekd later that either i installed the guide uoside down (i didht) or some epoxy fell off of sometimg or other and i can order replacement parts. No thanks. Cheaiest POS $350 gizmo i ever bought. I regret buying it and consider the lack of durability only s liability in a handgun. Rip off.
