Anyone know of any type of indoor benchrest pistol matches.

I guess first off would be do define what makes a "Benchrest pistol". when I was shooting center fire we had LRPs, long range pistols, like the xp-100... they typically had longer barrels but shot in the bags like a Benchrest rifle without a rear butt stock...

My Thomas rifle sets in the bags like a pistol would, because it has no butt.  but it's not typically referred to as a pistol.

@pbike If it is Thomas carbine minus the Butt pad and cheek rest it's a legal AFFTA pistol.
