Matrix Precision Sig Sauer Aluminum Mainspring Seat, Standard Grip

This mainspring seat is aluminum with an anodized finish, available in black, blue, or red. Unlike the original plastic one, it will never break.

Models: P220, P226, P228, P229 (Standard Grip, not E2)

Note: Not liking plastic parts, I always wanted to have aluminum mainspring seats in my Sigs. It's not that the plastic ones don't work well, because they do for the most part. However, I know of one gentleman reporting on Sig Talk that his plastic one broke after 200 rounds.

Just received the 2 frames this afternoon. They are fantastic, as usual. You have certainly converted me to become a builder rather than a buyer.

Your rail cutter is amazing like I knew it would be. I think with your tooling almost anybody can perform an above standard job.
