Interesting topic .
I've been considering putting a better trigger on my older 6920 and
never even considered this issue .
I don't have the block , but there's an extra section of aluminum
that wasn't machined out of the lower . It's also one of the very
last Colts made with the larger trigger pin .
I REALLY wish the ALG ACT was available for large
pin lowers .
