low-light situations. My test gun came with a green light pipe installed. Nine accessory light pipes are included, three each in green, red, and white, so you don’t have to worry about lost or broken sights since plenty of replacements are provided. Spacers and shims are also provided for adjusting length of pull (LOP) and drop and cast. The LOP on my test gun was set at 13-1/2 inches, which was a little
short for me. I left it, but probably would’ve benefited from adding an additional spacer. Three Briley choke tubes are also included. For those unfamiliar with Briley chokes, they are the choke of choice for serious clay target shooters. Their inclusion with the 940 is a definite plus. As mentioned, a gold accent band adorns the extended portion of each choke. The three constrictions provided are cylinder, improved
cylinder, and modified. During testing, I found the cylinder tube to be a little too open for all but the very closest targets. Modified was a good choice for longer shots, but three-gun competitors will likely use the IC tube most of the time. Test loads included 1-1/8-ounce Remington Gun Club number 7-1/2s at 1,200 feet per second and number 8s at 1,145 fps, and Browning BPT Light 8s at 1,145 fps. Everything cycled and ejected perfectly. In three-gun competitions, 2-3/4-inch target loads with small shot sizes, like 7-1/2s or 8s, are commonly used, although the occasional stage may call for slugs or (rarely) buckshot. I also took the 940 JM Pro to a Ducks Unlimited sporting clays shoot where I ran 100 rounds of Browning BPT Heavy 1-1/8-ounce 7-1/2s at 1,200 fps through the gun. There was only one failure to eject. Since the other 99 shells of the exact same load all functioned properly, I’m inclined to believe there was a problem with that individual shell, not the gun. After the shoot, my shoulder felt just fine, not beat up as it often is from other guns following a 100-target event. Finally, I filled the 940 to capacity with 10 rounds of 1-ounce Winchester Super X Game Load 7-1/2s at 1,290 fps and let her rip. All 10 rounds flew out the gun with ease, and there was minimal muzzle rise or recoil. Sadly, it was all over in an instant, leaving me wanting to repeat the drill over and over. I can attest to the fact that 940 owners may find themselves frequently expending a lot of ammunition, both competitively and recreationally! Those looking for a shotgun that’s out-of-the-box ready for three-gun competition need look no further than Mossberg’s new 940 JM Pro. It has everything you need to get started conveniently rolled-up in one reliable, ready-to-go package.
