^^^ just keep your eye out for a fa carrier...if the opportunity to acquire one cheaply pops up I'd buy it and install it if I were you. Two reasons...
1. most buyers of that gun in the future would want a fa carrier so plug n play sear host as God intended.
2. You'll find yourself at the range or around hk guys or dealers at some point and Im sure someone will lend you a pack to shoot in it.
carrier isnt too expensive in the scheme of things. I'd say sell/trade the semi carrier and buy a FA carrier. Or better yet...keep the German semi carrier and buy/install an inexpensive RCM FA carrier. Boom. Done.
