They say the extractor may well break.
I polished the chamber on mine when I was polishing the feed ramp. Did not help with steel case. I well shoot 15-20 steel rds slow fire but it does heat up and chokes. A friend reloads .45 acp on his progressive for me at very reasonably prices.
I want to send mine to Tommygunner for a detachable butt stock, SBR it with improved rear sight and comp. I wish I could afford the full auto but the War department would deport me if I did that.
