L&R's new Classic cap lock is a true conversion. The pan is still evident on the lock plate. The pan molding and flash fence have been retained, and the pan groove has been enlarged to accept a 1/2" diameter powder drum and nipple.

L&R's new conversion lock is made to be a tight fit in the Siler lock mortise, and is a tiny bit larger, with a longer tail. This lock has a fly, tumbler with cam-action mainspring, raised bearings to minimize friction, and a short hammer fall for fast lock time. L&R's clever new "one position" tumbler returns the sear to the same angle, whether uncocked, half-cocked, or full cocked, a nice feature.
