You should really find a rifle with a swamped barrel and hold it before you buy, it is not about weight it's about balance, and looks, I wouldn't buy an early style gun with a straight barrel but that's just me. Now on a southern gun or a tennessee rifle I'd go with a straight or tapered barrel, but I wouldn't go with a siler lock on one of those rifles I'd go with an english style lock such as a chambers late ketland lock. These locks fit the rifle better and are correct, TVM will put whatever you ask them to install on it, since they hand inlet the stock for the lock. The late ketland is known for being fast.
