Atlas Gunworks 29 Round 9mm 170mm Competition AlphaLock Magazine for 2011 Pistols
The Atlas Gunworks 170mm Competition AlphaLock Magazine is built for shooters looking for maximum magazine capacity in 9mm 1911 double-stack and 2011-style pistols. Designed around Atlas Gunworks' premium magazine tube, this complete competition magazine combines a 170mm tube with a competition spring and follower and Atlas' toolless AlphaLock basepad.
With a standard capacity of 29 rounds, this magazine is an excellent choice for USPSA Open Division and other competition applications where maximum capacity matters. The AlphaLock basepad provides quick, toolless access to the magazine for cleaning and maintenance.

Optional CSRG Competition Spring & Follower Kit
An optional CSRG 1911 Double Stack / 2011 Competition Spring & Follower Kit can be added to your order. CSRG states that its competition kit can provide 29/30+1 capacity when used with 171.25mm Atlas/Checkmate magazines equipped with competition-style basepads.
Important: The CSRG kit is an add-on product and will not come installed in the magazine. Your Atlas magazine will arrive with its original Atlas spring and competition follower installed, and the CSRG spring and follower will be included separately for customer installation.
Slide Lock: Both the factory Atlas competition follower and the optional CSRG competition follower are intended for competition use and are not designed to lock the slide back when the magazine is empty.
Before selecting the CSRG option: View the CSRG Competition Spring & Follower Kit product page for complete installation, capacity, break-in, and compatibility information.
Compatibility

Fitment Note: Magazine and magwell compatibility can vary by pistol, grip, magwell, and production generation. Some newer pistol configurations may have dimensional differences that affect aftermarket magazine compatibility. Verify compatibility with your specific pistol before ordering.
