I have up to four Sig 320 fire control units without manual safeties that I would like to swap for manual safety-equipped fire control units (aka Massachusetts compliant versions).

My FCU's are "upgraded" (they have been to Sig for the voluntary upgrafe), originally came in 9mm compact and full size 320's, and are stock. I have not done any kind of trigger work to them. These units are all low round count (300 or fewer rounds) and have not had any issues.

I am looking for stock FCU's that have been "upgraded" by Sig and fit 9mm/40S&W frames, though I would certainly consider FCU's with professional trigger work done.

I'd be happy to pay a small fee to facilitate a trade - $40 per FCU and we each cover our own shipping. If you have medium size grip modules that accommodate the safety, I would also like to trade grip modules or buy yours if you have no need for a trade.

Thanks for looking and let me know what you have.
