I would also consider Brad @ https://bahnhofmachine.com , he does amazing work , very reliable, he learned or honed his skills under Mike @TSC .
also Got Uzi in OH does some amazing work .
Mike has a Beretta 92 Barrel of mine been like 2 years, never heard back . Went the Mk Tactical route, where Mike still works and they passed the message, but no barrel.
I concur Morgan @ class 3 machining in TX . Do not under any circumstances send to Tornado Tech in OR , you will never receive communication , your gun or money back.
