The Brouwer M1811 grip module corrects the main ergonomic issues with the p320 platform – high bore axis, rounded slippery grip, short beavertail. The modern M1911 pistol is the standard for shooting performance, control, and ergonomics. The overall grip shape, feel, and design of the modern 1911 has not been replicated until now. With the design of the SIG P320 series, we were able to bring some of that performance and control to polymer pistols.
