SIG P211 GTO Aluminum Magwell
Price range: $65.00 through $70.00
The Grayguns SIG Sauer® P211 GTO magwell is a high-quality, lightweight aluminum design. It is one piece of the puzzle to help competitive shooters meet the weight requirements IDPA’s Enhanced Service Pistol Division. The design and function are the same as the OEM steel magwell, but our design is approximately 1.2 ounces lighter.
Select from 7075 Unfinished or 7075 Type III Anodized Aluminum.
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 with the heaviest magazine to 43 ounces or less. The firearms – with the largest magazine inserted – must also fit in the IDPA gun test box measuring 8 3/4″ x 6″ x 1 5/8″.
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.

Great upgrade from the original stainless one. Product looks better in person too. And they gave a discount. Whats not to love lol
Perfect fit and finish as expected from the Grayguns Team. The magwell got my P211 to 44.8oz with a 17rd legion mag and Romeo2. That puts me right in there for IDPA CO.
