Before ordering any lock right now, be sure to inquire of the maker / seller if the recent steel quality issues have been resolved. For the last year or so even the best lock producers have been plagued with difficulty in getting good, consistent quality steel to work with. A semi - custom maker informed me mid - last year he had to return a quantity of locks to a maker due to poor quality steel. Seems most of the steel used nowadays is recycled and sometimes inconsistent in makeup, and for some applications, in this case lock parts, variations in heat treatability have become a problem. Most of the time the manufacturers are catching the bad parts before they get out the door, but a few get through.
Some barrel makers were having similar problems, but it has been more of a matter of unpredictable variations in machinability, not safety.
