>>63990775 (OP)Between the options presented, the A300 is best. Mossberg tries, but their 940 series is getting increasingly expensive while continually lagging behind Beretta and Benelli.
The A300 is a US made budget version of the 1301, which is very good, arguably the best semi auto combat shotgun available. Unlike the 1301's rotating bolt head, the A300 has a more conventional locking block that pops up out of the bolt to lock into a barrel extension so it isn't as smooth shooting and the A300 also has a less advanced gas system that doesn't cycle as quickly. Neither of these things are deal breakers or really necessary for an HD shotgun, but nice to have if you plan to actually shoot a lot and have fun with the shotgun.
If you are trying to keep things VERY budget friendly, especially considering that there's a non-zero chance of an HD gun disappearing in an evidence locker for God only knows how long if it is ever actually used, then Mossberg's pump shotguns are worth considering. They are a fraction of the price of any non-Turkish semi-auto and absolutely dead nuts reliable. In practical terms, the rate of fire difference is insignificant and the risk of short stroking is overstated so long as you practice with the gun at all. Mossberg 500, 590, maybe a Maverick 88 but that is getting really cheap.
If you do want to roll the dice on Turkshit, get a MAC 1014. It is a 1:1 parts interchangeable copy of the Benelli M4, but you do need to shoot it a lot to make sure you didn't get a lemon and send it in for warranty service at the first hint of trouble. I don't really recommend it because you have a budget for non Turk shotguns, but I have one and it runs great.
