One of the reasons I retired in very early 2018, rather than the planned end-of-2018-or-later, was being required to patrol in the tiny new Ford MBUVs. (Make-Believe Utility Vehicle.) A partial short-term work-around was was to switch to smaller G19 duty pistol, from the preferred 1911 or G17, which meant a reduction in accuracy potential. Another concern was there being no clear path to exit quickly with the long gun, or to maneuver and fire the long gun from within the vehicle.
All I really wanted was to be able to keep driving a Tahoe, on patrol. (It was not that I had gotten big; I was wearing Blauer duty trousers with a 34” waist, and was still able to get into 32” VertX cargo pants. I am 6” tall, with long legs/arms.) My division commander would not honor the long tradition of letting high-seniority officers keep driving our older vehicles.
Getting my hand properly onto the grip of a handgun, in a Safariland 070 or 6360 duty holsters, at 0300, was never a problem, even when seated in the micro-Fords. The clearance problem, in the micro-Fords, was maneuvering room, especially when I was seated on the right side.
