Colt Lawman Mk iii problem...?
I recently (as in Sunday) picked up a Colt Lawman mk iii. My friend came over today, and upon him handling it for a bit he said that the holes in the cylinder for the bullets looked a little small for a 357/38. I didn't have any live ammo to try, but I took some spent 38 casings and upon trying to slide them in I discovered they refuse to go. I tried numerous casings, but no luck. I am kind of concerned at this point... I am not the best with revolvers, so I don't know of this is normal or what. Is my cylinder messed up or something? I checked to make sure the plunger wasn't loose and blocking the holes. Any advice???
