Ha !!!!
That's a little bit funny!! If Uberti would address the short arbor issue, there wouldn't be a "problem"!! The spring is a joke!!
How in the world do you get " hammer bounce" with a cartridge gun ?!!! I can see a light sprung cap gun dealing with blowback through the nipple but this is a cartridge gun for Christ sake!!!! My cartridge .45C S.A.A. copies have a just under 3 lb hammer draw and even with "heated" 45 rounds don't have an issue with "hammer bounce" !! I'm sorry, just makes no sense . . . sounds like "fix as you go" engineering!!! Lol!!!

Maybe with the addition of a "spring" fix, Uberti is finally admitting there is a problem?!!
