I bought a new Tanfoglio EAA Witness 45 ACP with a 22 conversion kit recently. When I finally got it to the range, shooting 45 was great. Very nice and accurate, almost like my CZ75.
But when I put on the 22 slide and barrel, it was nothing but trouble. I'd say 70% of rounds got jammed. There seems to be two problems: first, the barrel entry seems a bit too tight as many of the spent casings were stuck in there and I had to pry them out. Second, the cartridges weren't feeding up from the magazine to the barrel right. It was like the angle was too low and they were trying to go against the base of the barrel instead of up and into the barrel.
Any ideas about what I should do? Will it fix itself as the gun gets broken in, can I fix it myself somehow or should I send it back to EAA? I have heard bad things about their customer service.
