Got my Sinsinati Pump action 14 inch 12 gauge from Corwin Arms the other day, finally had an opportunity or two to give her a test run and evaluation.

First off, came nicely packaged with two five round mags. I was able to pick up another 10 round mag from a local dealer, and have a few more mags on order. The only thing missing is an instruction manual; don't know how to get this thing apart yet, though it doesn't seem too difficult I don't want to start tearing things down and missing parts without knowing what I'm doing!

The gun seems solid and well built; heavier than I expected it to be but that's a good thing insofar as recoil. The pump action is super smooth. The spring assisted pump action takes a little getting used to, and I know some people don't like it but after trying this out I kind of like it! It required a different manual of arms than say a Remington 870, but I found that holding the gun with pump racked open with one hand while rolling in a tactical reload, then releasing your hold on the forearm resulted in a super fast reload as the action slammed forward a la semi auto. Maybe you can call this a semi-semi auto?

The gun comes choke capable with a breacher style choke installed and two more removable (Beretta Mobilchoke style?) chokes and a wrench. Also has a 3 position collapsible pistol grip stock, a knurled forend cap with sling swivel, a full length picatinny rail on top and more rails on the bottom for flashlights, lasers, etc. Tacticool right out of box!

Then, there's the sights. Ah yes, the sights. These are the same found on most Turkish import AR style guns coming into Canada - rear carry handle with front post. In a nutshell, these are ka-ka and look cheap and flimsy. So off they went, and on went a red dot.

After an initial quick swabbing of the barrel, it was off to the range to try it out with a variety of shells. Loaded up both five round mags and let her rip. Functioning was great and the action was smooth but the trigger was a little stiff and spongy. (It got noticeably better with use though.)

Then it happened; halfway through the second mag, my Tasco Red Dot Red/Green scope fell apart. I didn't bring the open sights with me like an idiot, but luckily enough I had my Mini 14 with a detachable Bushnell .223 Tactical Scope on it so I mounted that on and fired a few rounds.

Here's a pic or the shotgun with the Tasco optical sight mounted on and 10 round magazine:

Fired some slugs at 50 yards with the optic sights; group on the bottom is Winchester 2-3/4 inch 1 ounce, group on the top handloads with Lee 7/8 oz Slug:

If it weren't for the trigger, both would have grouped substantially smaller with the Winchesters shooting into one raggedy hole! The gun certainly likes slugs!!

Fired a variety of other shells, including Winchester AA target loads, Winchester White Box and Remington 00 9 pellet buckshot, and handloads of Lee Rifled Slugs and .690 Lead Round Ball loads. Great functioning and nice patterning with all loads. Here's a pic of 00 Buck at 20 yards:

Gun functioned and fired great. I had a total of three stoppages, one ammunition related (an oversized reload) and two magazine related jams; this is a common problem with any magazine fed gun that uses rimmed cartridges. You have to make sure that when loading, the rim of one shell doesn't ride over the rim of the other, otherwise you get a horrendous jam that required removing the magazine and jiggling the offending shell out. Also, you have to be careful loading high-brass shells as they can catch the rim of the shells going in. If you pay attention to what you're doing, should be as reliable as any other tube fed gun.

While I've heard this gun can handle 3 inch shells, I'm only interested in 2-3/4 inch anyway; the larger capacity mags apparently don't feed a full 10 rounds of 3 inch mags reliably.

All in all, I was extremely pleased and pleasantly surprised with the quality and the functioning of this gun, especially since I got it for under $300!!

I have since replaced the optic sight with flip up AR style sights, and a light/laser combo under the barrel. (Can't post pics cause I'm only allowed three lol)

Great truck gun, range toy and overall fun gun!! (BTW - you can put chokes and get two round mags for hunting if you want)

Here's my list of Pro's and Con's:

Pro's:

(1) Nicely built, solid and compact.
(2) Lots of rails to hang things on.
(3) High round capacity but short overall length
(4) Super smooth action
(5) Reliable with all 2-3/4 inch loads
(6) Telescopic rear stock fits any size shooter

Con's:

(1) No instruction manual
(2) Cheesy factory sights
(3) Spongy and heavy trigger
(4) Bolt will not stay open due to spring

Totally thrilled with this gun, super value, and tons of fun to boot! Highly recommend to anyone!!

Kudos to Corwin Arms for a great product and great service!

I'm thinking you can remove the pump return spring without affecting function. Same as with the Asil Bulldog pump guns.

That was my thought..... unless it is like an SAP6 and doesnt actually lock closed and relies on that spring to keep it in battery.

Contrary to popular belief, these guns DO lock closed irrespective of the pump action spring. (So does the SAP 6). The locking lug is on the upper part of the bolt/barrel much like a Remington 870. If it wasn't there, you would be kinda dead as the bolt can't stay closed on spring pressure alone! The only thing it doesn't utilize is a bolt release ala Rem 870. Whether the gun has been fired or not, you can open the action of the Sinsinati by moving the pump back. (If you want to see for yourself, make sure the gun is safe and completely unloaded and put a 12 gauge cleaning rod down the bore and try to push the action open; you won't be able to because it's locked into the barrel until you manually pump the action back and unlock it.)

In looking at the design of the gun, I would say that the spring's primary function is to put just enough pressure on the fore end to keep it from moving, thus doing away with the need to have a manual bolt release.

I suppose you can remove the spring if you like and it would be quite safe, but in all honesty I kinda really liked it once I started to get used to it! Super fast for tactical reloads, and really smooth to boot.

Did you try the original sights to see how accurate they were? Also if you have seen/ operated an as46 how do they compare, quality/operationally! Thanks.
I have one coming soon, glad to hear they are good. I just received 2 10 round mags from Lockhart and they were good once I oiled them up and ran 10 rounds down them a few times. Also do we have to buy another 2 round mag or can we block one of the five rounders down to 2. Cheers, Bob.

I bought the 10 round magazine at Wolf's Den near Barrie. The Mag was actually for the AS-46. They had some in stock (the AS-46) and I handled one-practically identical to the Sinsinati. Any magazine for the AS-46 will work in the Sinsinati. I believe Trigger Wholesale in Ontario is the distributor for the AS-46 and spare magazines.

You can plug a 5 rounder yourself for hunting, and it doesn't have to be a permanent modification either to be legal.

And yes, these shotguns were on sale at Corwin Arms for $297

Thanks, yea mine should be here next week, shipped last Friday, I ordered my 10 round mags through Lockhart tactical but they were shipped from Trigger, so they either direct shipped or Lockhats is A subsidiary of trigger! Looking forward to running this rig.
You cant have a loaded shotgun in your home, this is the next best thing for speed of loading.

Ahh, Im picking up what youre putting down. Interesting. Didnt know that. Will test it would when I see one next.
 
Just got mine, so far, yep it is heavy, sturdy though too, I don't think the sights will work for me, stock is cool but comb drops off too much for my liking! I oiled the 5 round mags and they smoothed up like the 10 rounders I got from Lockhart. The mags insert and lock up well. The 10 round as46 mags are a tiny bit sloppier than the 5 rounders that came with the gun. The trigger is really bad on mine, I didn't find it spongy but very heavy and gritty, however I haven't taken it apart and cleaned/ polished it either. The forearm needs more grip ( at least for me) with the return spring, the forearm wants to slip out of my hand a bit, that can be fixed!
The breaker style choke is nice/ subtle and the other chokes look good, I will be stripping it down in the next week to clean and polish/smooth things out, then to the range! This is a staunch shotgun, I like it so far and hope it feeds well at the range!
 
Martin at Corwin Arms is a really nice guy and great to deal with, I'm fortunate to live close to Kamloops :)
 
Mine arrived and it's a beauty. Decent trigger and cycles fantastic with flawless ejection.. on full weight dummy rounds. Hoping to get out today to shoot it. I also didn't much like the factory sights and slapped on some flip up ones i had laying around.
 
Got one as well, quality looks pretty good. Unfortunately I got more bad news from my doctor the day this arrived. Anyone looking for one check EE, mine will be going up with 4 AS46 mags.
 
Took mine out today. Shot a mix of 2, 4, 7.5, 00 and slugs. Gun fired every time only issue I had was mag related. Not broke in yet or oiled etc. But had a couple double feed issues and while cycling the action it would slide the top round over the lip of the one below and lock open the action.. I think once I get the mags dialed in it will be a awesome shooter. Will also try and find some uzkon mags
