Absolutely false. There is nowhere near the amount of tinkering required with say a Chambers Siler or a Davis lock, than there will be with Traditions locks. Traditions locks are small, more like pistol locks than rifle locks. Take dinky little 5/8ths flints, and there is barely any room once the flint strikes the frizzen. If the flint is even just a tiny bit long it will hang on the frizzen and not drop the cock all the way down.
IMO, if it's all you can afford then yes buy one, however if you've got a little more dough in your wallet, I'd go with something better. And No, I'm not saying to go buy a Kibler, but I'm sure somebody here will chime in and recommend one.
