I brought a 1917 home from the pawn shop a couple months ago, have run some 45 acp. and some 45 autorim thru it, and the cylinder has been opened up for 45 Long Colt, however havent had a chanch as yet, the barrel has been cut back to 3 in. as far as a handgun goes, I would not feel underguned if thats what I had at the time it was needed, after all we all carried revolver before they started marketing those black plactic handguns with those light rails, and survival packs hid somewhere in there ( Just a quick JUMBO moment) ha ha JIM
