When you're depending on a slender subcompact semi-auto pistol with your life, you want rigid, aggressive serrations on the slide that will give your fingers an ultra positive grip should you need to rack it in any stressful, muddy or bloody situation. We've applied this principle to several GGP slides already, and knew it had to also be an option for the GGP365 slide. Speaking of options, the GGP365 slide comes cut compatible with the Shield RMS-C or SIG ROMEOZero micro red dot optics, with an attractive G10 coverplate for when a MRDS is not in use.

Cycling problems? The VMOS™ brings the discipline your rifle needs.   For difficult setups like suppressed rifles and exotic caliber chamberings, some degree of mass regulation is required for optimal performance. This is especially true in the absence of an adjustable gas block. Residual gas and excessive fouling can grind your rifle to a stop. One size never fits all when it comes to gas-operated rifles. The Variable Mass Operating System (VMOS™) carrier ensures reliability through additional reciprocating mass but provides more custom tunability.

The Reptile is a Sig Sauer P320 compact/carry compatible aftermarket slide that Norsso manufacture in-house at their shop in Las Vegas. They start with a 17-4 stainless steel billet, and CNC mill the critical dimensions creating a slide blank. To achieve the ability to modify the exterior of the slide, Norsso leaves mass in the forward area of the slide near the muzzle. This allows them to remove more material in other areas of the slide for porting, customization and enhanced serrations.
