I still own two Model 1907s - one original with delexe wood and another that I had made up into a rifle that was actually used by the likes of Baby Face Nelson and John Dillinger during the 1930s. The Lebman 1907 has a metal forearm with a Thompson vertical grip. Several of these were recovered from the Dillinger gang when they were captured in Tucson Arizona. In fact, the original style rifle was extremely popular with both the good and bad guys in the 1920s and 30s. If you look at the gun caches recovered after bad guy shootouts in the 1930s there will always be one model 1907 or more. Apparently the round out performs its paper ballistics punching though the heavy car doors of the time (45s from Thompsons would sometimes bounce off!!) and even through bullet proof vests. Having a 10-round magazine, legal, from the factory was a big deal as well.
Cowboy interest wise, the 351 Winchesters were used by the Texas Rangers - who had to buy them with their own money - that's how much they thought of them.
If you are going to shoot them you should reload - I haven't set up for this caliber yet, but I will. I was able to accumulate over 300 original rounds and shoot them on occasion keeping the brass for the future. I also was able to get 6 of the 10-round mags - built like a tank and have never misfed. I don't think they have much of a kick but the trigger pull does take some getting used to.
The 1907 Winchester is a very important historic weapon from before WWII that nobody remembers.
By the way, the Model 8 Remington is great too - "Ride the High Country" is a terrific movie that does indeed have Warren Oates using one. I have one in 30 Rem caliber and she's a honey too.
