The full-size is almost as long as a government-model 1911, the Centurion is almost as short as a Commander 1911. IMO, the Centurion is proportioned more like other common service pistols such as the USP and P226.
3rd gen DAO trigger pulls probably have more variation than any other gun I have seen. Some of the parts (old, flash-chrome "forged" parts) are unbelievably corn-cob rough, like they were rough blanked and never actually finished. The newest production 5946 I handled was from probably the last run made around 2014, sitting under glass at Cabela's a few years ago. Action parts were MIM, and the press was very smooth.
