I have a new lone wolf g21 barrel and carver 3 port comp in the classifieds that I planned to do exactly this with , and never picked up the g21

I have shot underwood 45 super and some similar hand loads out of the factory barrel and a Kkm in my g41 with no issues

Rabid Creedmoorians ring my doorbell ...
