Connecticut Shotgun Manufacturing Company is proud to announce our new CSMC Model 21 Over & Under

Manufactured in our facility in New Britain, CT to the highest standard. This is the over and under version of our currently available Model 21 Side by Side. We build this gun using all of the same machining, tooling, techniques, finishes and the original process. The Model 21 Over & Under is a very low profile, shallow frame, very similar in feel to the Side by Side Model 21. They are virtually the same height and weight with the same balance that made the Model 21 famous. We are offering a Standard Grade with a blued receiver, a #6 Pigeon Grade and a Grand American. Initially available in 20ga. only.

This new Model 21 Over & Under is available in 3 Grades:


Frequently Asked Questions

It is an Over & Under version of the time proven Winchester Model 21 Side by Side design. We use the same machines, tooling, methods and finishes as we do on the Side by Sides. It has the same feel, balance and looks, almost identical to a Side by Side Model 21.
The Model 21 Over & Under, as with all Connecticut Shotgun Manufacturing Company guns, are manufactured in its entirety in New Britain , CT. On occasions some smaller parts or initial machining operations will be sub-contracted if we are over capacity, in an effort to deliver products on time. We do not assemble parts that we procure. We machine virtually everything ourselves. They are designed, machined, assembled and finished in our own facility in New Britain, CT, USA. We have nearly 3 acres of manufacturing space on one floor.
YES, in 1996, we purchased the Model 21 division from U.S. Repeating Arms Company, and we received all the tools, fixtures, and processes to build the gun.
This is a trademark process by Connecticut Shotgun Mfg. Co. After the barrel blank is gun drilled and turned, the barrels are put into a very deep freeze. This releases any stress that the metal has endured during the forging. This procedure prevents warping and twisting of the tubes, even after firing multiple shells and reheating the barrels. This is the best method that we have found to make sure the tubes remain perfectly straight.
This is a trademark process by Connecticut Shotgun Mfg. Co. After some of the critical parts are machined they are hardened with Hard Gold™. In this process the parts are gold washed to prevent rust, and a special hardness is added that will significantly increase the life of your Model 21 Over & Under.
This is a trademark process by Connecticut Shotgun Mfg. Co. It is a very hard internal plating, that allows you to shoot any type of shot that we know of without damaging the barrel. We decided to do this because many shooting ranges and hunting areas are restricting the use of lead shot and might eliminate lead completely.
It was founded in 1975 by Antony Galazan who is still the President and CEO. He still operates the business personally, at every level possible. It is a small privately owned company.
We have vast expertise in producing shotguns and we are a small efficient company without bureaucratic layers of personnel.
Yes - in all respects. Just as the side by side Model 21 is a strong well built gun, the Model 21 Over & Under is also.
Engraving and checkering layouts are performed by our proprietary process. The actual drawing layout is very time consuming, by doing this we allow our craftsman to devote their time to the actual work, producing a better end result. The actual finish work is performed by hand. We have a team of people that do the checkering as well as the engraving. That is why they are all slightly different and not exactly as pictured in some cases. It is indistinguishable from a complete hand engraving or checkering.
You can call and ask, but it can not be guaranteed.
Yes, it has great investor value. They’re strong and will provide a lifetime of service. If you were to look at our customer base, you would find many of our customers are the most note-worthy shooters of our time that could use and shoot any gun they wanted to. And you will find that many of them select Connecticut Shotgun guns because of their dimensions, refined handling styles, and they tell us they shoot better and enjoy them more than any other gun.
Winchester had designed a Model 21 Over & Under many years ago, but chose never to build it. It is something we had planned for a long time and felt that it would be well received by our shooters and group of customers.
Yes, it is our trademark Tuff Bore system that allows you to shoot any type of shot through our guns. This is very important when you consider that most double guns are not able to handle double shot and this includes most barrels that are side by side.
When you consider that an older Model 21 in 20 ga. Side by side is currently selling at about the $10,000 level, and you can purchase a Model 21 Over & Under 20 ga, that brand new and built to order for less than $3,000, if you take advantage of the discounts, it is an exceptional value.
It is the original bolstered shape of the outside of the frame the way the Model 21 was originally designed.

Model 21 Over & Under Specs

  • Bluing: All Model 21 Over & Under barrels are blued in the traditional method of rust and caustic bluing.  We use the original Winchester process of Du-Lite bluing solution and we polish using the same methods and techniques.
  • Wood:  We use American black walnut, which is the traditional Model 21 wood.  On the higher grade pieces, you get more of a feather crotch, and we cut it with a more traditional Winchester layout where the feather runs from the comb to the toe.  You can request other wood like California English walnut, and we will quote that.  Our company buys more high grade wood than any other company; therefore we have a large selection.  We store wood and dry it here and even have some original Winchester stock blanks that we use occasionally.   
  • Checkering: The checkering is performed by hand with mechanical layout.  24 lines per inch, 3.1 ratio.  The Standard Grade comes with traditional Model 21 multiple point checkering. See Picture.  The #6 comes standard with A-carved checkering. See Picture.  The Grand American comes standard with B-carved checkering.  This is very complex and time consuming.  You can mix or match the checkering styles with any grade, and we will quote it.

  • Checkered Butt: We are offering the option of a checkered butt for an additional $450.00(this price may increase in the future).
  • Engraving:The Standard Grade does not have any engraving although it is beautifully polished. The Model 21-6 Pigeon Grade engraving features traditional Model 21 scroll, and has dogs engraved in the panel on the right and left side.  There are two pheasants on the bottom.  The #6 is basically a Grand American without the gold inlays.  The Grand American is engraved with traditional Model 21 scroll, and all the dogs and pheasants are inlaid in gold.  Please keep in mind that these are inlaid and engraved by hand so there are slight variations in the engraving.  If you need specific dogs or birds, you must request that and have that on your order sheet.  Any other special engravings can be quoted. 
  • Stock dimensions:The stock dimensions of this gun are 14 3/8” LOP, 1 3/8” drop at comb, 2 ½” drop at heel.
  • Ejectors:  There are selective automatic ejectors.
  • Steel: Both the barrel steel and the receiver come from Steel Mills in the US.  The receivers are a special pre-hardened forging as all Model 21 receivers were made. 
  • Regulation:  All barrels are regulated at 40 yards to shoot flat.
  • Ejector blades:  They are made from forged blanks.
  • Trigger guard:  Pistol grip or straight grip both have long tangs and are shaped in the traditional Model 21 fashion. 
  • Recoil pad: The Model 21 Over & Under comes with a Winchester Patent Date pad.
  • Choke tubes:  Each gun comes with 5 choke tubes, they are steel shot compatible. Skeet, Improved Cylinder, Modified, Improved Modified and Full.  This makes the gun very useful especially considering the fact that you need to use steel shot in many situations.
  • Springs: The Model 21 uses coil springs exclusively. 
  • Chamber Length:  All Model 21 Over & Under’s have 3” chambers.
  • Forends:  This is a specially designed forend for the Model 21. 
  • Pistol grip:  Pistol grip stocks have a traditional Model 21 metal grip cap that is blued and has one screw.
  • Single trigger:  It is a single selective trigger. The trigger pulls are approximately 4 to 5lbs.
  • SST setup: It operates on an inertia system and the gun needs the recoil of the first shot to set up the second barrel.
  • Weight and balance: The gun with 28” barrels is approx. 6 lb 5 oz.
  • Wood finish:  We use the traditional Model 21 wood finish and coloring that has been traditionally used on the Model 21 helping preserve the legacy of the gun.
  • Fit and Finish:  The Model 21 maintains the same high standard as the Model 21 originally did from its inception in 1930.
  • Wood drying:  Connecticut Shotgun Mfg. Co. has a lot of experience in buying and handling the very best wood the world has to offer. We find the old growth Black American walnut trees for the exemplary Model 21 Over & Under stocks. We dry all of our own wood here in our own facility.
  • Experience:  Our first gun, which we still produce, was our ultra high quality A. Galazan O/U. We started making them in 1993 and it has gained acclamation from all over the world as being one of the world's finest shotguns. Additionally Connecticut Shotgun Mfg. Co. has many years of experience building double guns.  We are currently the only manufacturer in the USA of high quality double barrel shotguns.  We also manufacture a full line of tools and accessories for shotguns, and we trade many high grade new and used shotguns, allowing us to study and compare many other types of guns. We also build the Parker shotgun for Remington and the Wayne LaPierre RBL for the NRA. We have become the custom shop for the Winchester 21 as well as building the gun in its entirety. We have had many awards bestowed upon us by our peers.
  • Warranties:  The Model 21 Over & Under carries a five year limited warranty on manufacturer defects.
  • Safety: Standard guns come with automatic safety.
  • Gold trigger:  All Model 21s are gold plated unless specified otherwise, just as the Custom Shop did.
