I had a S&W 1917 that some moron had rechambered to .45 Win Mag. It was still in one piece, despite the thin cylinder walls. Whoever did the rechamber job must have lived under a lucky star if he shot it much. I traded it for a Remington 1100 20 gauge skeet gun at Corey's in Littleton, NH, about 30 years ago, but, for some reason, I still have a couple dozen half-moon clips somewhere around.
