I have handled both the DT10 and the Blaser. Bought the Blaser 32" sporting model. I believe the Blaser to be superior due to the trigger mechanism and the quality of observable workmanship. I have had a number of problems with new Berettas, some addressed by the MD warranty facilty, others ignored.

After shooting the Blaser exclusively, I returned to the Beretta 687. I saw target, thought I have pulled the trigger, but no boom. I really had to slap that Beretta trigger, or so it seemed.
