I am considering the Sig 1911-GSR Revolution Carry in 45 caliber for home defense. My wife & I shot both the Sig220 & Sig-GSR at our local range. My accuracy was good with the Sig 220 but my accuracy with the Sig 1911-GSR was excellent. Has anyone else shot the Sig 1911-GSR? And if you did shoot this gun was the gun reliable in feeding and functioning. I was considering the .357 mag for home defense but that handgun would probably make me both deaf & blind if I ever had to shot the gun inside the home. The most important thing to me is --is this handgun reliable? Most of my shots were in the 4 inch red bullseye! My wife had all but 4 shots in the same bullseye from 15 feet away out of 10 rounds. What do you think of the Sig 1911-GSR and its quality? Thank-You for your feedback!
