Given that titanium has a lower coefficient of expansion it doesn't seem to make a lot of sense, but I've the same thing in a couple places.Tracker Backer C45 said:The gun testers mail offer subscription, claim that when shooting the new 445TBC Titanium revolver it locked up from over heating.
However, they give a big thumbs up to the regular steel 445 that is $250.00 less in price, weighs only 8 oz. more, and is a great .44 carry gun.
Anyone out there have over heating problems with their 445TBC? I'd sure like to find out if these gun testers are right or not.

A possible explanation might be that titanium's use together with steel hadn't been thoroughly wrung out in guns, based on the fact that the two expand at somewhat different rates. For instance parts made to close tolerances based on the COE of titanium could theoretically be pushed too close together by an adjacent steel part.
