I would say check it yourself. Twist rates can vary even in the same model and same caliber, and barrel length has zip to do with twist rate.

To find the twist rate, pull or push a cleaning rod with a tight cleaning patch in the barrel. Either add a tape flag to the rod or make a mark on the rod. Stop pushing the rod when the tape or mark is straight up. Put a yardstick next to the rod with the end at the mark. Start pulling the rod again until the tape or mark has made one complete revolution and note the number of inches the rod traveled. That is your twist rate. For example, if the rod turned one revolution in 12", you have a 1:12 twist rate.
