I got a TC Renegade flintlock and it had the early lock with poor geometry. All they changed is the cock. The cock that is on there can be reforged to work satisfactory or what I will eventually do is just replace the whole lock with a better option. The cool thing with most of TC stuff is you can swap out barrels really easily. I hand forged the cock, rehardened the frizzen, and slapped a French amber flint on there and it sparks as good as a cheap mass produced lock is going to spark.
