LaserMax offers five new models for full- and mid-size GLOCK pistols: LMS-1131P (G19/23/32), 1141P (G17/22/31/37)1141LP (G34/35/17L/24), 1151P (G20/21 and 1151 PFGR (G20FGR/21FGR). These LaserMax models come in response to customer requests for captive recoil springs, just like the GLOCK factory parts. The P-series models are now even easier to install, but provide the same reliable and rugged functionality. All LaserMax sights can be installed in a matter of minutes and are every bitas rugged as the gus they are installed in.
