The Hunter One Trigger is just like any other trigger...the relationship or distance between the top tang and the trigger strap is critical...also, the slightest sliver of wood or dried oils that ran down the firing pin holes will cause the inertia block to stick or hang up...I've never had a problem with a Hunter One Trigger and I own three at the moment...two of which I shoot rather abusively...With Smith's, I can usually tell if there is a single trigger problem just by looking at the top tang screw behind the safety...before I buy it
