Our frame is a ground-up Shadow Systems design, not a rebrand of another frame already on the market.  Our tooling uses new technology to wrap more texture around the curves of the frame and put the grip in places not normally seen on production guns.  The slide and barrel are machined in-house in Plano, TX.  Barrels are 1-10″ conventionally rifled 416R stainless steel.  Our barrels are coated in super hard Bronze Titanium Carbo-nitride or Black Nitride.  Slides are machined from 17-4 PH stainless steel and coated in Nitride.  Slides feature front and rear directional serrations.  These serrations provide excellent traction when manipulating the slide, but are relatively frictionless when drawing the pistol from a holster.  The MR920 features deeply recessed front serrations and corner chamfers.  This thinned front profile gives greater control and reduces the difficulty of inserting the pistol into a holster, particularly a partially collapsed IWB holster.  Their pistols are built for reliability and performance first.  Triggers are improved over a stock trigger, but leave internal safeties fully intact and use stock weight springs.  You can expect smooth take-up and a super crisp break at 4.0-4.5 lbs.
