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* The Mossberg 940 Pro JM gets consistently positive marks from owners, particularly those who use it in competitive shooting. Reliable cycling is the most common positive. The semi-auto action handles varied loads cleanly and maintains its rhythm under extended use. Reduced felt recoil is a regular mention, which helps during long competition days. Build quality and ergonomics draw favorable comments. The matte blued finish holds up to handling, and the adjustable stock is appreciated for accommodating different shooters. The competition-focused features (loading port, oversized charging handle, pinch-free elevator) are noticed and appreciated by shooters who have used other platforms. Weight is the most common criticism. At 7.75 lbs it is on the heavier end of competition shotguns, which some shooters feel during extended matches or carry. Price is occasionally flagged as high, though most owners accept it as appropriate for a purpose-built competition gun. Overall the 940 Pro JM has a strong reputation in its category. ## Pricing **5 offers available** | Vendor | Price | |--------|-------| | Gritrsports Com | $849.99 | | Buds Gun Shop | $887.49 | | Kygunco Com | $918.99 | | Gunbuyer Com | $949.93 | | Guns Com | $978.99 | ## Similar Products - [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 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 Semi-Auto Shotgun | Digital Camo 12GA](https://gunsnation.com/p/mossberg-940-jm-pro-semi-auto-shotgun-digital-camo-12ga/UCHGDJDc) - [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 930 JM Pro - 12 Gauge Semi-Auto Shotgun, Matte Blued Finish](https://gunsnation.com/p/mossberg-930-jm-pro-12-gauge-semi-auto-shotgun-matte-blued-finish/UCHGDJ5r) - [Mossberg 940 JM Pro 12 Gauge Shotgun - Tungsten Grey Finish](https://gunsnation.com/p/mossberg-940-jm-pro-12-gauge-shotgun-tungsten-grey-finish/UCHGDJA2) --- *Data from [GunsNation](https://gunsnation.com)*
