Each link opens the video at the moment quoted.* > Feel much of a difference between the bird shot and the buck shot and that was full power double up Buckshot and The Recoil is very similar to the low brass bird shot. > > — [1ShotTV](https://www.youtube.com/watch?v=qoKaU9vgGgQ&t=143s) > Boy that trigger can really go I did not expect it to go that fast and it kind of surprised me to be honest. > > — [1ShotTV](https://www.youtube.com/watch?v=qoKaU9vgGgQ&t=245s) > Like a Mossberg and I think Mossberg makes great shotguns especially for the money so it's no belli M4 but I would say this is probably the best semi-auto shotgun I have ever tried. > > — [1ShotTV](https://www.youtube.com/watch?v=qoKaU9vgGgQ&t=401s) > The price on these is what makes them so appealing I love it it ran perfectly and I would definitely recommend. > > — [1ShotTV](https://www.youtube.com/watch?v=qoKaU9vgGgQ&t=599s) ## What Customers Say *AI-generated insights from customer reviews* Competition shooters who use the 940 JM Pro consistently note the high round capacity and smooth gas-operated cycling as the gun's main strengths. The 9+1 capacity is specifically called out as a differentiator for 3-gun stages where magazine tube extensions would otherwise be needed. The Briley chokes are appreciated as a meaningful factory upgrade. The Hiviz sights draw positive mentions for visibility. The adjustable LOP is valued by shooters who want a precise fit for fast mounts. Ease of cleaning comes up regularly as a positive. The gas system is designed for simpler disassembly than older semi-auto platforms. Recoil management is generally noted as good for heavy competition loads. Price relative to competitors is discussed, with most buyers concluding the competition-specific features justify the cost for serious 3-gun use. Owners who want it for hunting or defense sometimes note that lighter or more compact options might suit those roles better. ## Pricing **17 offers available** | Vendor | Price | |--------|-------| | Guns Com | $649.99 | | Buds Gun Shop | $969.99 | | Grabagun Com | $969.99 | | RK Guns | $979.99 | | Shootingsurplus Com | $1001.10 | | Gritrsports Com | $1002.99 | | Primaryarms Com | $1009.99 | | Impactguns Com | $1012.79 | | Kygunco Com | $1017.32 | | Centerfiresystems Com | $1017.99 | *...and 7 more offers* ## Similar Products - [Mossberg 940 JM Pro Semi-Auto Shotgun 12GA - Tungsten Gray](https://gunsnation.com/p/mossberg-940-jm-pro-semi-auto-shotgun-12ga-tungsten-gray/UCHGDJDV) - [Mossberg 940 JM Pro: 12GA Semi-Auto Shotgun - Black MultiCam](https://gunsnation.com/p/mossberg-940-jm-pro-12ga-semi-auto-shotgun-black-multicam/UCHGDJ58) - [Mossberg 940 JM Pro: Elite 12Ga Semi-Auto Shotgun - Black/Tungsten](https://gunsnation.com/p/mossberg-940-jm-pro-elite-12ga-semi-auto-shotgun-black-tungsten/UCHGDJ4k) - [Mossberg 940 Pro Tactical 12GA Semi-Auto Shotgun - Optic Ready Black](https://gunsnation.com/p/mossberg-940-pro-tactical-12ga-semi-auto-shotgun-optic-ready-black/UCHGDJBP) - [Mossberg 940 Pro JM 12GA Semi-Auto Shotgun, Matte Blued Finish](https://gunsnation.com/p/mossberg-940-pro-jm-12ga-semi-auto-shotgun-matte-blued-finish/UCHGDJ9v) - [Mossberg 940 Pro Turkey Semi-Auto 12GA Camo Shotgun](https://gunsnation.com/p/mossberg-940-pro-turkey-semi-auto-12ga-camo-shotgun/UCHGDJE7) --- *Data from [GunsNation](https://gunsnation.com)*
