THIS FINISH IS NOT DONE BY GLOCK.
NP3 finish is an electroless nickel-based finish for steel, stainless steel and aluminum alloys that co-deposits sub-micron particles of PTFE (polytetrafluoroethylene), otherwise known as Teflon, with electroless nickel. NP3 permits firing for longer periods of time between cleaning, dirt and powder residue have no wet or oily surface to cling to. When cleaning is required, the effort needed is minimal - usually requiring only a soft cloth.
The G43 is the new single stack, 9mm pistol. The G43 is the most highly desired and anticipated release in GLOCKs history. The G43 is the answer to your everyday concealed carry needs. It's ultra-concealable, accurate and fantastic for all shooters regardless of hand size. The grip has a built in beaver tail design which allows the shooter to acquire a high and tight grip. The aggressive texture of the grip lets the shooter more easily operate the pistol. The large magazine catch allows for easy removal of the six round magazine. Engineered to the same standards, the G43 can withstand the same tortures as other GLOCK pistols.
