I have some local trainer friends who teach a well-regarded shotgun class. I decided to take it to learn some things about how to use a scattergun, which of course meant that I needed a shotgun. My choice was a cop trade-in Remington 870 Police pump-action shotgun. At first, this might seem like a very un-Parvusimperator choice, so let’s review the reasoning.
- It was cheap. I picked this thing up for less than half the MSRP of a brand-new 870P. So I’m getting to class on the cheap, which is nice when I’ve burned through my training budget and am saving for a fancy USPSA Open pistol.
- It’s quality. The 870P is made with better parts than a regular 870, and this one is old enough to date from back before the “freedom group” axed Remington’s QC department in search of greater profits. So I have a cheap, reliable gun that I won’t have to worry about going wrong mechanically in class.
- I like the idea of taking an old, beat up shotgun and making it mine. Sort of like adopting a pet, but for guns.
- If I ended up disliking it, I could probably get all my money back selling it, given that I bought the gun used and that it’s a desirable Police model 870.
Upon unboxing, I discovered my shotgun was as expected. Date codes on the barrel told me the shotgun was built in 1995. In the meantime, the synthetic furniture on it had been beaten to hell and back. Someone had gouged “VAULT” in the stock. The ‘brass bead’ sight no longer had any finish resembling brass. The receiver was well-patinaed, and had a good bit of rust.
On the plus side, all of the metal is sound, and the action is very smooth. Running it is a joy, and brings a smile to my face. Also, I have no complaints about the trigger. It’s not something superfancy, but it also has no glaring problems.
I didn’t have a ton of time to get the shotgun ready for class. Clearly, I wouldn’t be able to get it cerakoted or anything, and I was expecting class in the rain. I did have time to make a couple changes in preparation. Did you really think I would not? I added a Magpul SGA-870 stock and a Wilson Combat +2 extension.
I’ve talked about the Magpul stock before. But it bears talking through again. Magpul put a lot of thought into this stock. It’s the best stock out there for shotguns. It’s super comfortable and is easily adjustable for length of pull. I’m not a tall guy, and I don’t have gorilla arms, so I normally get very annoyed at the very long length of pull on factory stocks on shotguns. They’re probably “tradition” or some nonsense. Anyway, problem solved, problem staying solved. It also comes with a nice rubber recoil pad. Replacing the old rubber recoil pad is something that should be done on general principle given the age of the shotgun and how much abuse the old stock had gone through. As a bonus, the stock came with some sling attachment points.
Lots of people make magazine tube extensions. I picked the Wilson one because the price was reasonable, the quality is good, and it came with all of the other extras I wanted, namely a new high-visibility follower, a new magazine spring, and a front sling attachment point. The high-visibility follower is very helpful in a class environment for administratively verifying that the weapon is unloaded. Even if I didn’t get the magazine tube extension, I would have wanted to replace the magazine spring because I don’t know the age of it.
On to class! How did the shotgun do? What did I learn about the parts? And what is coming for our rescued shotgun?
My shotgun ran great in class. Several others had shit break on their guns. One guy had the handguard become detached from the loading forks. Another had a screw come loose inside his receiver and jam things up. People switched to backup guns. But my old 870 Police Magnum gave me no trouble at all. Despite being old and unproven (to me), I had a great time with my shotgun, and my small initial investment paid off.
My existing mods were also good choices. My instructor friends are also huge fans of the Magpul stocks. I found that it did everything I asked. I got the length of pull adjusted to suit my preferences, and that helped. The stock even made supporting and firing the gun one-handed reasonable.
I also had no complaints about the extension. More ammo is better. Duh. The spring worked great. No jams. Plus, the high visibility follower was in fact very visible.
What I did find unsatisfactory was the two-point sling. I rigged this up like I would rig up one of my carbines, using a VTAC sling. This wasn’t my best build plan ever. Having a sling mounted in front of the handguard on a pump shotgun ended up being super annoying, because it seemed like it was always getting in the way. Plus, the shotgun always felt askew when it was hanging on the sling. On a carbine, I’d just move the sling adapters, but I can’t do that here. This will take some more thought.
The ‘formerly-brass’ bead sight on the shotgun was a reasonable sighting system. It wasn’t great. For most “indoors” distances, it will work fine if you’re using something with a pattern like non-flite-control buckshot or birdshot. I found that at distances, the lack of a good second reference made headshots with slugs harder to achieve than I would like. I will probably end up getting the shotgun drilled and tapped for a picatinny rail so I can mount a small red dot. Because I freaking love red dots, and I love the target-focused shooting paradigm that they get you into.
While the gun worked great, there are things that need changing. I’ve talked sights, even if those are “wants” more than needs. A bigger priority is the finish. The one on the gun is toast. When I asked gunsmiths in the class about getting the rust off, they told me not to worry about killing the finish, because it’s already crap. Not that 870s are known for their good factory finishes. This is going to get redone in…something. I don’t know what yet. Stay tuned.
