COMPLETE GROUPS CAN'T BE SHIPPED OUTSIDE THE US, THE OTHER PARTS CAN
The COMPLETE CUSTOM TRIGGER-GROUP is listed in two versions, one with a light trigger spring and one with a Crosman Custom Shop adjustable trigger spring. The light spring version has a trigger pull of around 8 oz. The adjustable version from 1-6 lbs. Those pull estimates are of the unmounted trigger groups, not including extra pull produced by the striker pushing against the sear when installed. That varies a lot with striker-spring tension, the total pull once installed will be anywhere from 8 oz to 7 lbs. Both groups include a custom-installed overtravel adjustment screw under the trigger. This is a brass-tipped stainless steel screw that is shorter than the ones on Crosman Custom Shop models and installed at a more natural angle. Unnecessary forward movement of the trigger is completely eliminated by the trigger design. The overtravel screw is adjustable to control how far the trigger can continue to move after the hammer releases. The groups are adjusted to around 3/64" (.046") of trigger travel. Further adjustment to shorten or lengthen travel may be desired. Too short of travel will prevent the gun from firing when the trigger is pulled. This creates a dangerous situation where the hammer is partially released, it could fire unexpectedly in this condition. To correct this safely, fully cock the gun and engage the safety. Then adjust the screw away from the trigger until it will fire correctly.
The CUSTOM TRIGGER COVER is machined from 6061-T6 aluminum. It's listed in two versions, plain aluminum or anodized black. It fits the current Crosman & Benjamin pistol trigger frames that have three mounting screws for the cover. This includes models 1377C, 1322C, PC77, P1377, P1322, 2289G Backpacker, 2240, 2250, 2300T, 2300S, 2300KT, 2400KT, 1701P, 1720T, Marauder Pistol and all other models that use the same trigger frame cover MPN 1322B044. It will not replace the older die-cast metal covers that only have two mounting screws MPN 1322A044.
The CUSTOM PISTOL TRIGGERS are listed in 360 brass, 6061-T6 aluminum or black anodized 6061-T6 aluminum. They are ultra-thin, extra-wide, extremely comfortable, smooth working, make the trigger pull feel lighter and improve accuracy. They fit perfectly to eliminate unnecessary wobble, no shims or spring washers are needed. The thin trigger blade leaves a lot more room inside the trigger guard which greatly improves comfort, especially for adult sized fingers. Unnecessary forward movement of the trigger is completely eliminated by the trigger design. No other trigger in the industry comes even close to this level of comfort and performance. It's extremely durable and will easily last the life of your gun. It will work great with a standard sear but for the best performance we suggest our custom sear. These fit current and older Crosman models 1377C, 1322C, PC77, P1377, P1322, 2289G Backpacker, 2240, 2250, 2300T, 2300S, 2300KT, 2400KT, 1300KT, SSP250 and may fit other models that use the same type of trigger frame. These triggers do not work with the two-stage groups on 1701P, 1720T and Marauder Pistol. If your model isn't mentioned contact me to find out if these will fit your gun.
The CUSTOM SAFETY is listed in two versions, one machined from 360 brass, one from 6061-T6 aluminum. It's slightly larger diameter to fit the frame and cover better than the original plastic version. In rare cases you may need to remove burrs or excess paint from inside the hole the safety slides through in the frame. Otherwise the safety won't slide into the safe position. A small piece of 300-600 grit wet/dry sandpaper can be rolled into a small tube and inserted/twisted into the hole to remove the excess material. This should be done with all of the parts removed from the frame and it should be cleaned thoroughly before assembly.
The MAGNUM SEAR is a new version released on 6/29/18 made of heat-treated 410 stainless steel. It's more rounded and polished than the older version for the smoothest possible function. It's harder, more durable and works smoother than custom sears made by most others and will wear far better than a standard sear. It's wider than standard to eliminate unnecessary wobble. Just like our custom triggers, no shims or spring washers are needed, it leaves only enough clearance to work smoothly and allow the hammer to seat correctly. It produces a lighter, smoother trigger pull and a cleaner release of the hammer. It fits Crosman models 1377C, 1322C, PC77, P1377, P1322, 2289G Backpacker, 2240, 2250, 2300T, 2300S, 2300KT, 2400KT, 1300KT and similar models that have the same type of trigger frame. It's too wide to fit the plastic trigger group on 2260, Discovery, Maximus and Fortitude models, It does fit the custom aluminum trigger casings we list for those rifles.
The LIGHT TRIGGER SPRING is 0.8 mm wire diameter, 7.1 mm OD, 5.5 mm ID and 33 mm long. If installed as shown it stays in place on the sear, doesn't touch the trigger frame or cover and works very smooth. It took us a long time to find just the right spring for this purpose. Instead of extra-thin wire ( which tends to be unreliable, unstable, inconsistent and unsafe ) it has more coils closer together to reduce compression force. This allows it to produce a very light, stable, consistent trigger pull and reliably return the sear all the way to the top for full engagement with the hammer. Trigger pull will vary by hammer spring tension and how smooth your hammer and sear function. With standard factory models you should be able to get a pull of 1-2 lbs. 1/2 - 1 Lb with models like the 2300S that have a very light hammer spring. Heavier hammer spring tension increases trigger pull because added force on the striker holds the sear in place tighter. For the best accuracy, striker force should be reduced to the minimum needed to produce the desired FPS. The power adjusters I have listed are designed for this purpose, they can reduce or increase the hammer spring tension. The sixth photo shows this spring compared to a standard spring. The third photo shows how this spring should be positioned against the sear with the end of the spring wire gently touching the right side of the sear.
The ADJUSTABLE TRIGGER SPRING is a genuine Crosman Custom Shop part made of solid brass with a steel spring. It's adjustable from about 1-6 lbs of trigger pull in addition to how much pull it takes to release the hammer in your particular airgun. With standard factory models you should be able to get a trigger pull as light as 2-3 lbs. 1-2 Lbs with models like the 2300S and 2300T that have a very light hammer springs. Hammer spring tension has a lot of affect on trigger pull. Heavier hammer spring tension increases trigger pull because added force on the striker holds the sear in place tighter. For the best accuracy, striker force should be reduced to the minimum needed to produce the desired FPS.
The TRIGGER and SEAR PINS are sold as a pair. They are made of hardened alloy steel, much smoother, harder and more durable than a standard pin. They are also a full .125" diameter (Crosman's are .124") so they fit better reducing unnecessary wobble. They fit all 1377, 1322, 1300KT, PC77, 2289, 2240, 2250, 2300T, 2300S, 2300KT, 2400KT, 1701P, 1720T, Marauder Pistol, 1720T, 1701P and similar models with the same type of trigger frame.
