I have a friend who has a circa 1971 1894 in 44mag. It has the older style carrier. He is having the feeding 2 jam, where as the carrier lifts the cartridge another one feeds from the magazine and sits under the carrier. I don't see much wear on the carrier. I was wondering if you can use a new style carrier in place of the old one. Parts are getting difficult to find. I have pics of an old style stripped carrier and a new style one. Thanks for any help.
