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 used to have a full page add of these in an old popular mechanics magazine at the time. it also had a oicture of a foot operated launcher for indoor skeet shooting mini pigeons called ‘Mosquitoes” that could be bought for basement skeet shooting etc. looked like an old 8mm movie projector with a stack loaded feed and an air powered foot release on hose like camer shutter remote pump release

    I just recently acquired a Crosman Trap Master 1100 CO2 air shotgun. I need to find some 80 grain lead roundballs (.38 caliber). Also the skeet shells. I believe they are plastic. Not sure about the wads ; if I can use something else in it’s place or not. Any ideas? Steve

    The shells are out there on eBay and elsewhere. For wads, just use a piece of heavy cardboard.

    Are there any Crosman 1100 barrels available? How about reasonably priced resealing kits?
