...It held fine even with the straight barrel being nose heavy... The weakness of the Dixie TN gun is the lock. It sucks... Its a cheap factory made gun. It will shoot and you can hit the mark with it. Its not perfect or particularly pretty though...
I own one: a .50 flintlock. Ken pretty much says it all. I replaced the (truly horrible) triggers with a Davis set I had on hand; replaced the lock. Won't win any matches or beauty contests, but it makes me a pretty good "rattin' around out in the boonies" rifle.
The impression I got when these first hit the market was they were intended to be a "user", for those of us who'd never be able to afford an original (or bench copy) SMR to pack around in the hills, but who wanted something a little more "Southern" than was factory-available at the time.
Your satisfaction with this - or any - rifle depends entirely on what you're looking for in a rifle, and what you expect it to be.
But I certainly wouldn't be concerned with a modification ruining any inherent collector value in one of these.
Just my opinion: not worth a penny, but it's mine.
