Product Overview:
Springer Precision has designed and created the 140mm extended capacity magazine for the Smith & Wesson M&P 9mm and .40 S&W using precise CNC machining methods that offer a lifetime of durability. The product is hard anodized and offered in 4 different colors. The unique locking mechanism allows for a very solid attachment with a simple backing out of the discrete set screw. They are specifically designed to work with our magwells and fit the USPSA 140mm magazine gauge. The unique attachment provides a sleek low-profile design that is very stable and easy to remove.

Custom engraved and custom colors are non-returnable

Due to design variations, Springer Precision cannot guarantee compatibility with any other manufacturer’s aftermarket magwell, unless otherwise specified. 

Please note: It's crucial to test and verify compatibility before using in competition settings, especially with 140mm/170mm magazine configurations. Variances can occur between mass-produced magazines, particularly in the magazine lips connecting with the extension/basepad.
