AJ, there's darn few shotguns I haven't shot someplace and time. 40 years of shotgunning means lots of neat toys. My experience with the 1300 has been limited to shooting those some private students brouhgt to the range, and was positive. The 1300s did what I wanted them to.No glitches.
Md DOC tried the 1200s, and later some 1300s. They didn't hold up as well as the 870s did. Neither did the S&W 3000 series.They didn't even try the Mossy. In fact no shotgun could stand up to the neglect, abuse and misuse common to prisons like the 870.
6 million 870 owners didn't get that way because of good marketing. Remington set out to make a pumpgun as durable, reliable and smooth as their model 31, or Winchester's Model 12, without all the expensive machining those excellent designs entailed.They built a better, cheaper mousetrap and the world beat a path to Ilion....
Besides durability and reliability, the 870 is quite easily operator maintained. The list of addon and aftermarket parts is amazing.
Name one model of shotgun introduced since 1950 that has aftermarket parts to match, from new bbls to trigger groups.
Also, I've shot trap with a fair amount of folks savvy about shotguns lately. Bet I've not seen three 1300s out there in the last 6 months.
However, IMO, the 1300 is a decent shotgun fully capable of more than most operators can get from it. ENjoy....
