We have been in touch with a company in California that offers recoil reduction muzzle breaks for rifles and shotguns. They also offer a recoil reduction treatment for handguns. The process involves laser porting the top of the slide and barrel. The company says that on a 5" 1911, the recoil will be reduced by 95% and roughly 50% on a 3" model. We send in one of our personal Kimber Ultra Covert II models for the treatment so that we can put it to the test.
