I hear chambers locks are the best.a buddie of mine has the L@R on t/c pa hunter had to reinletted He seem to like and has no problems: could be just a bad lock I do here good reviews,I almost bought one (think they are located in the carolinas) but there warranty was so,so too me.
I have 3 flinters all t/c all work outstanding all have the new hammers and t/c upgraded frizzen( I myself like lyman frizzen added to a t/c lock) and with there new ventliners and there warranty I find t/c locks o.k.
