This is a brilliant...
This is a brilliant collaboration between Sig and Proof Research. The ability to rapidly change barrels with the drop-in has increased my shooting happiness. I define rapidly as something I can do in under 30-minutes and not having to take to my local armorer and wait three months. The Proof barrel is everything I thought it would be from my years of research and talking with the Proof team.
