Does anyone know of any info about converting inerta triggers to mechanical so one can shoot 12 and 410 in the same gun using tubes? (Yes I know only a gunsmith should do the work but good ones are far and few)

The two big tube makers...Briley & Kolar could do it but that doesn't help you "downunder"..you might ask them how to do it. On my Perazzi, which is inertial, my gunsmith just installed a bigger inertial block rather than try and convert them to pure mechanical. Works great.

ok Thanks for the reply DB
