Richard, what you did not tell us is particulars about the gun and its intended purpose. Double set triggers without a half cock were common on target rifles back in the era of picket and slug guns. Have one made by Peter Reinhard myself, a light picket from 1876. The lock is not what I'd describe as cheap, for the entire gun is an exercise in quality hand craftsmanship, with a release in the <2 # range. For target work it's straightforward: load and bench the gun, then put a cap on with the hammer at full cock....and shoot. It's not a rifle one would take hunting for the most part, due to weight. So, that's my perspective based on a sample of one.
