This is a 4.5 Echelon with custom porting. Slide and barrel cuts with nitride finish. Shoots super flat. Way flatter and softer than OE comp. Is fully reliable with original recoil spring. Looking to trade for non comp slide,barrel, and 250$ cash on your end. If you have been looking into porting your pistol this would be an easy swap. Would like a good condition low round count barrel and slide. No optics included. Thanks
