    So I am going to be getting a new tac/hd shotgun and have narrowed it down to a Mossberg 590A1 with a heavy barrel or a Mossberg 590 with a heat shield. All other aspects of the sg are the same as far as I can see. So which one do you prefer and why. The price difference doesn’t matter to me.

    I went with the 590A1, twice. Since they are both home defense guns, they don't get shot to the point where a heat shield is really necessary.

    The heavier barrel of the 590A1 seems to balance better than the thin barrel with the heat shield attached. YMMV.

    How much does the 590A1 weigh? Do you know about the 590 wt?

    My favorite shotgun I currently own is my Mossberg 590 20" 9 shot with the heat shield. It feels great in my hands and the action is very smooth with about 3K rounds through it. It balances well for me but I am pretty good size. Having said that I am waiting on a Mossberg 590A1 18" 6 shot with the ghost ring sites. I plan to replace the barrel with a 14" barrel as a SBS for something different. I should have the 590A1 with the 18" barrel next week and can comment further but I doubt it will take over my favorite spot.

    I also have a 500 Mariner. I am not sure what is different with that other then the coating but it sure feels heavier.

    Mossberg site shows the weight it depends slightly on the model but beed sight 9 shot 590 and 590A1 both show 7 1/4 lb.

    I shot a mil spec 590A1 when I was in the military and I owned a civilian 590 special purpose w/ bayonet lug.

    My opinion is that I actually liked the 590SP better. Why? Well the thin barrel actually felt lighter to me. (maybe it was in my head though?) I also liked the blued finnish vs the parkerized. It just looked nicer. The fact that it had a plastic trigger guard and plastic safety selector didnt bother me and probably perpetuated the assumption that it made it lighter? lol.

    The bottom line is, I am not going to throw it in the back of a Hummer and use it to do CQB fighting in Afghanistan. Both go bang reliably and both take a bayonet for zombie CQB. I only paid $300 for the SP but I guess if I had the choice to get a mil spec A1 I would probably like to have it just for kicks & giggles if I had a few extra bucks?

    My 18" 590A1 w/5+1 capacity is already muzzle-heavy. I can see the 20" w/extended mag being even more so. I think the lighter barrel on the 590 would make balance feel better, but I guess that would be a matter of preference.

    The Navy requested the heavier barrel to make it more resistant to dents when doing cqb work. My shotgun is for cqb work, so I chose to follow their lead.

    Besides, what's the purpose of a heat shield on a shotgun? Is the heat mirage going to interfere with your aim at 15 feet? Not likely. You gonna grab the barrel for some reason? Me neither. I understand why a thicker walled barrel would be nice, but I don't see the point of the heat shield.

    Protects the barrel, keeps you from being burned by a hot barrel during weapon retention or other handling (ie: placing back in a scabbard when switching to carbine, etc).
    I have a 590 with standard bead sight and the heat shield. I ordered it with the SpeedFeed stock, and have been very happy. However, the SpeedFeed stock seemed to make the shotgun too long overall to easily use in close quarters, so it has been replaced with a Knoxx Breachers Grip pistol grip. I kept the full stock in case I want to switch back, but I love how my 590 handles with the Knoxx grip on it.

    I have the standard 590 with factory heat shield and factory ghost rings. I shoot it a lot at the range and I like the heat shield.

    Heat shields were placed on shotguns that might be used w/ bayonet for up close poking on or in enemy personnel. Rarely used in HD but one never wants to cut ones SD options... sides that, you want to scratch your barrel taking it off and putting it back on, right?

    Usually, Less is More (unless you're tricking out your civilian AR-15/M4). A light, a sling (maybe) a few extra shells on it. GTG

    Bayonet? :whistling:

    Maybe. Why not? They seem to upset certain politicians (or maybe it's just the bayonet lug... ya think?)

    The bayonet lug can also allow you to quickly add a picatinny rail for a flashlight. Im currently trying to find one such adapter, but the ones I have seen so far seemed unsatisfactory.

    The heat shield in addition to protecting your hand from burns during a bayonet fight after a bout of sustained fire also actually works quite well for preventing impact dents to the barrel during rough use.
    Consider it a bit of added security.

    I think the real benefit of the heat shield is the same as that of a ventilated rib. It keeps your sight plane free of heat waves coming off of the barrel that could obstruct your vision when aiming.

    About 15yrs ago I had a 590SP. It was a great shotgun and should have kept it. But I plan on getting an A1 next time. I like the heavy barrel over heatshield.

    So I ordered the 590A1 last night. I’ll keep everyone posted on the results when I get it.

    I hope it works well. Mine should be in any day now. I already have a 590 20" with heat shield so I am covering my bases. I ordered the A1 through Bud's and had to send the first one back.

    Just another ball of mud.
    Government experts have determined that the heat shield prevents skin cancer.

    On that one shoulder anyway.:whistling::whistling:

    I could never get my 590 to heat up enough to actually burn my hands. I tried. But the heatshield did provide durable protection under heavy rough handling. Not needed in my opinion. Does look cool though.
