I was over at Pistolsmith.com and was reading a post on the Beretta pistol that he was going to purchase one of these from A place called LTD. What exactly is one of these things? Thanks.

Its LTT not LTD and is run by Ernest Langdon who is an IPSC champ on the Beretta team.  He has a bump which is installed on the rear of the trigger which eliminates over travel.  He is know to do the very best Beretta trigger jobs in the industry and competes with what he makes.  His level II trigger job includes a "D" spring (lighter spring from the DAO model) the speed bump trigger and all his hand fitting and polishing.
