All troubles with the Hunter One Trigger (Lard's patent) are caused by the design shortcomings of the gun in which it's installed, and/or the tamperings of the incompetent.

It's funny that Lard triggers in Westley Richards guns have no such bad reputation but when that trigger is used in a Smith it suddenly becomes an incomprehensibly complex, unreliable unit that "America's best" gunsmiths won't touch?
Give me a break.

I suggest that you read the Guncraft section in the March/April 2010 issue of Shooting Sportsman. There you will find all you need to know regarding Allan Lard's fine design.

As far as repairs, I wholeheartedly recommend Jerry Andrews. He understands how these triggers function and is willing to work on them.

Happily, my days of working on Smiths are past.
