Crosman Trapmaster 1100

The Crosman Trapmaster 1100 One of the more interesting guns from the venerable firm of Crosman was their Trapmaster 1100 shotgun. Powered by a pair of 12 gram CO2 cartridges and firing a reloadable .38 caliber plastic shotshell filled with #8 shot, the Trapmaster wasn’t a huge commercial success, being made only from 1968 through 1971. It was sold not as a hunting gun, but as part of suburban trapshooting set, using a hand thrower and two-part, snap-together plastic “pigeons.”

Of course since it was made, airgunsmiths have found it to be an excellent platform for customization. 1100s have been converted to bulk fill and re-valved to increase power. Changing the valve spring or making a new, lighter, valve would increase opening time and the the volume of gas released. The guns can also, with no conversion, fire a .375″ lead ball over a couple of wads. One owner, writing in (I think) the now-defunct Airgun News, claimed 100 ft-lbs of muzzle energy for his conversion. A more realistic power level of 42 ft-lbs (465fps with an 80gr ball) is claimed at this web site. Whatever the capabilities, the 1000 was one of the best made, best looking guns Crosman ever produced, with a solid heft that put you in mind of a medium caliber firearm.

I owned two at various times, back when you could buy one for $70-80. These days a good example can command as much as $300, and a complete set with trap, shells, and reloading kit can go as high as $500.

    I just came across your airgun blog. I am incredibly impressed with the quantity and quality of information here. I am conducting research on a particular part of airgun history, and I am hoping you might be of some assistance to me. Could you please contact me at the email above? Thanks, and again… well done!

    I bought mine new in 1970 with all the accessories. I still have the plastic clays and the box but lost the other stuff. It also came with a hunting jacket with shell holders. My gun still works fine. I bought a bunch of shells and wads from a man along with a reloading tool about 15 years ago.

    I recently purchassed a group of guns which had two Trap Master 1100 in them. They both leak pressure. Can you inform me if they are sellable as is and if so what they would be worth. Secondly, could you inform me if anyone carries a seal kit for the guns. If I’m going to repait them I want to do it correctly. Thanks

    Crosman 1100s seem to go for 125-150, depending on condition. More if they’ve been converted to bulk CO2 fill.

    As for repair information- try Lutter Crosman Repair in Indiana. 291-485-8319.

    It takes two 12 gram CO2 Powerlets- the kind Crosman still sells. The first one goes in nozzle first, the second goes in the other way around. For shells you’ll have to hunt around on eBay and airgun sites.

    I have a Crosman 1100 Shotgun and Model 50 Trap kit, with shells, targets, and CO2 Powerlets, that were sold as a two piece Model 80 Set. They’re both new in the box, including the original shipping boxes and all manuals, removed only for pictures recently. I tried to list the set on eBay which pulled them because they don’t meet the “airgun” standard. Where would I best sell the set? Thanks very much!!

    I’d sell on the Yellow Forum:

    And perhaps also the American AIrguns classified section:

    Prices haven’t been that high on 1100s, which is kind of surprising. I’ve seen complete kits, in the box, go for $250-270

    I have a cool reloading tool for the 1100 trapmaster that my grandpa designed and built in 1974. It has a turrett that holds 25 shells. upper and lower wads set at the correct depth automatically. It is really cool and I will try to get a pic. I still shoot the gun regularly mostly killing starlings a bird that attacks our native birds in our area.

    A friend just gave me his old 1100 he’s had since he was a kid. he rarly shot it, its been in his closet. its like new. but because of the economy I need the money more than the 1100 now. How much is it worth? fair price that is. it might have a stuck valve the action wont seem to close. other than that it looks nice. I have no co2 or shot. it would be nice to keep but I can’t
