45 ACP can be used in both auto and revolver. The revolver must have a 45 ACP cylinder.
the 1917 colt revolver fired a rim 45 cal cartridge. however, half moon clips were used to insert 45 cal. auto shells and then place the inserts into the cylinder. In this manner both the 45 cal. rim cartridge and the 45 cal. semi-auto rimless cartridge can be fired from the 1917 revolver.
25 cents a round.
50-260 or so
50-150 USD or so
100-400
suggest you check with a gunsmith. I believe there is a slight difference between the 455 cal and 45 cal. however, I also believe the 455 cal can be changed (by gunsmith) to the 45 cal.
$500.00 is a good price.
You need to tell us what model of what firearm. Auto Ordnance made a .45 cal semiauto carbine and a 1911A1 pistol.
300 USd
500-15000 depending on EXACTLY what you have.
