This is a true two stage trigger system for the Crosman 2240, 2250, 2300S, 2300T, 2300KT, 2400KT, 1377, P1377, 1322, P1322, 2289 and others.

• Technically compatible with 2260 and 362, but you can't use the original stock that comes with the gun.

This is actually the Marauder Pistol Trigger Kit modified for compatibility with the models listed above.

• The kit works on CO₂ and pumper guns.
• The kit works with "normal" and "hidden screw" steel breeches.
• You MUST select the correct kit as the hammer (striker) is different for each.
• The pull test video below shows a pull of 0.50 lbs.

Here are the guidelines you need to follow:

• Pumpers will always take a "normal" pumper hammer. If you have a "hidden screw" pumper, that's a mod you specifically performed yourself and you're aware of the situation.
• The exception to this is the 362 100-Year Heritage Edition which, for the first time that I know of, uses a Hidden Screw Breech on a Pumper gun.
• Guns can ALWAYS take a "Hidden Screw" hammer, but it costs $5 more. This is your safest bet, but it's often not necessary to spend the $5.
• It does allow for more future upgrades though (you may, in the future want to upgrade to a Hidden Screw Breech).
• The guns that REQUIRE "Hidden Screw" hammers because they have "Hidden Screw" breeches are the 2300 series, 2400 series, 2240XL and a few others.
• The guns that TYPICALLY have "normal" breeches are the 2240, 2250, 2260.
• Refer to the photos below to see how you can check which you have.

The trigger is fully adjustable:

• The trigger stop screw is the visible set screw under the trigger. It prevents overtravel.
• There are two tiny set screws up and inside the 1/4" hole under the trigger (behind the guard).
• Those adjust preload, how the trigger rests against the sear.
• Then that brass knob controls the spring pressure to release the sear.

You will receive one trigger frame, as pictured, plus one applicable striker.

These photos show the "hidden screw" breech.
If you have one of these, you need and will receive, a notched hammer.
