Gun Stock Reviews: SIG P226 Caliber Exchange Tutorial

We were curious… How do you do a Caliber Change on a Sig P226 .40 S&W Police Trade-In Pistol??

There are two ways… Buy a complete Caliber X-Change Kit from Sig or…… Can you put a 9mm Barrel on a .40 S&W SIG P226 Slide, along with a 15 Lb Recoil Spring and a 9mm Magazine and make it work?? We are showing you both ways and we will let you decide, one is MUCH more expensive than the other one. #GSR
