Our experience was similar with some our our Deputies expressing an interest in the lighter recoiling of the 9mm. Complaining about the snappy recoil of the 40 cal. We, range instructors proposed taking a portion of our consistently lowest shooters and allowing them to carry 9mms. The management denied our request under the notion that in a gunfire there could be ammo compatibility issues with the different calibers. We countered with "hits win gun fights" and we do not practice sharing magazines or the transfer of magazines while shooting and were again denied. once the admin saw other agencies switching back to the 9mm then they decided and found the funding to switch. Nothing more then a newer, shinier can opener! Then it was a great idea.
