Maruder to pistol conversion

Years back Manny aka Nomadic Pirate had a 25 made. I believe it was a double tube with a 25 Marauder tube !.25" and the Discovery 7/8" tube underneath. Bob Cothran makes some hot rod valves. I think the gun was made by Marmit Militia at the time, custom double barrel band, air tube connections etc. Manny might be able to offer some suggestions he has a post on GTA.
 
I'm not a trigger sob. I can get familiar with most triggers. The Lelya trigger seemed good enough for me not to even think about adjusting. Nice light first stage, clear second stage. Maybe a little creep in the second, but as I push it it lets off a little right before the break. I figured out how to balance it right there as I line up on a shot. From there it is like a half ounce (or something crazy small) to break. I'm not going to change the trigger.
