Id suggest the biggest negative to 10mm as a PD gun is the recoil. The FBI saw scores drop when switching from 357 to 10, making qualification difficult with "small statured agents" (read that as females)
Actually , IF the comparison was .357 Silvertip 145 from 3 inch K Frame vs M1076 w/ FBI spec 10mm , recoil would have. Been non issue . But alas , the standard issue load was .38 +P , and actual .357 was case by case supervisor approval , for specific operations.
At Least as much as recoil , the issues were with the Physical Size of the M1076 . Both hand size vs grip girth , and bulky enough to spoil the lines on their Brooks Brothers suits .
