I have a Colt 1917 and a S&W 1917 in .45 ACP. I have to say I prefer the Colt.
My Great Grandfather carried a Colt 1917 in the AEF. I can’t see how he could shoot it, since he was a little guy, and those need at least medium sized hands to use.
Either gun is a fine self-defence weapon.The kind of gun that gives you confidence.
