Stealth Arms Platypus w/ Bull Barrel. Slide is RMR pattern and the gun is currently carrying a Holosun 507 Comp. The optic is zeroed for Federal HST 124gr. Trigger weight is 3lbs even on a scale. It is chainlink grip with Handleitgrip Extreme. Pistol includes 5 magazines, one mag sporting a TTI baseplate. Nothing is wrong with the gun, and it's only been fired for it's zeroing. The only reason I'm selling is simply because the gun is too small for my hands. It was extremely evident on dry fire drills that the gun just doesn't fit me.
