Think on it for a moment. This handy rifle, at only around eight pounds, offered one of the very first semi-auto capabilities to law enforcement and at ballistics that topped virtually any small carbine-sized rifle at the time, most of which were lever actions like the Winchester Model '92 in pistol calibers. Even today, this round will punch through a modern vehicle's sheet metal like butter, probably penetrate most soft body armor, and change any miscreant's channel permanently. And it's almost 100 years old.
The general ergonomics quickly make themselves apparent when you handle the rifle. It's reminiscent of the G.I. .30 Carbine, only much more accurate and hitting much harder. Although a bit heavy by modern standards, the extra weight calmed the recoil down to almost non-existent levels and made rapid, accurate fire easy for anyone in need of a problem-solver.
The unique bolt-operating feature of the 1907 deserves note. This ground-breaking semi-auto was developed in the very earliest days of the concept. As such, things were being tried that we may think of today as being quaint, but in actuality worked extremely well for the intended role.
Being a straight blowback, the bolt is connected to a weight that runs inside of the walnut fore-end. The collective mass of both parts slows the recoil impulse of the powerful round and makes operation possible. Otherwise, a locked breech would be necessary along with corresponding complications in operating systems. No gas tubes, no locking bolts, just simplicity itself. Perhaps there's something to be learned there?
The cocking rod protrudes from the front of the fore-end, and, while it seems awkward at first, you soon get used to it, and it feels quite natural, since your hand's there anyway. Is the bolt operating rod on an AR platform any less weird, I wonder? The safety on the 1907 is naturally placed under the trigger finger, like a Remington 870, and I'd hazard a guess it would take minimal training to transition a modern cop to this rifle.
