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!
