RE: Thumb trigger release 4 use w/ a D-loop??
Tru ball makes 2 styles,1 for hunter and 1 for competetion.The hunter is junk imo.As you found out,way too much trigger travel but the others are pretty sweet but they just don't fit my hand like a Carter.
Greg has the same release as mine except mine is a Fits Me Too which is just a smaller version of the Just Cuz and mine has the I.T.S system.
I have made the switch to Bt full timeand that is the way to go imo.It's even a little cheaper.[:-]
