Description The Grayguns SIG P211 GTO Aluminum Magwell reduces the gun’s weight. With the magazine inserted, the weight is reduced from approximately 45.66 ounces to 44.44 ounces, a 1.2-ounce reduction. Match rules for the International Defensive Pistol Association® (IDPA) Enhanced Service Pistol (ESP) Division limit the weight of the unloaded firearm. The limit is 43 ounces or less. Our P211 GTO Aluminum Magwell reduces the weight of the gun by 1.2 ounces. Our P211 Barrel Block reduces the weight of the gun by .79 ounces. Using both Grayguns components will get your gun down from about 45.66 ounces to 43.67 ounces. (We’re getting closer!) Weights are for informational purposes only. We suggest you weigh your own pistol as weights may vary. IDPA shooters interested in shooting the P211 GTO in the ESP division will need to get more creative to further reduce the pistol’s weight and height. Grayguns is in the R&D phase of additional components for the P211. The AL 7075 Aluminum Alloy is recognized for its exceptional strength-to-weight ratio, which makes it comparable to many types of steel. The AL 7075 Type III Anodized Aluminum combines the high strength of the 7075 alloy with the outstanding durability provided by Type III hard-coat anodizing. This results in a part that offers superior hardness, excellent abrasion resistance, and strong corrosion resistance, making it ideal for demanding applications, including firearms.
