Antimatter Industries Surefire X300 Wing Black. Why dont we see them outside of open division? Standard thumb ledges significantly widen your pistol and require a competition holster not designed for duty use. The Wing replaces your Surefire x300 picatinny side lug. Once you draw it auto-deploys letting you control recoil while still using your IWB or Safariland holster. With a little practice youll get it to collapse consistently with a one-handed re-holster. Its pretty instinctive.

Many kydex holsters work well without adjustment. Some kydex holsters that are a little tight can be easily modified to work. Users do not need to adjust their current grip. The thumb lands naturally on the Wing; however the Wing does work best with a thumb forward grip locking out the support wrist.
