I have three Sharps replicas--1 IAB, 1 Navy Arms (Uberti), and 1 Pedersoli. I shoot all three and love all three. No they're not quite as nice as a C Sharps, or others, but they cost less than half as much. I don't think you can get a better one for the price. I shoot the Sharps a lot. It loves the factory 405's, lead or jacketed. I also have a Uberti 45-70 Rolling Block in 45-70. They all get shot very frequently. I upgraded the tangs sites to higher quality ones, but other than that, they work fine.
I vote to go for it.
