Custom 360 brass safety for Crosman 2240, 2250, 2300KT, 2400KT, PC77, 1377, 1322, 1300KT, 2289G Backpacker and related models with the same single-stage pistol trigger group. It will also fit the Crosman and Benjamin PCP pistol models 1701P, 1720T and Marauder Pistol but the trigger may need to be deburred and polished on the top where the safety engages, this is shown in photo 5 and explained in more detail in the next paragraph. It's dimensions are slightly different to fit and function better than the original plastic safety. In some cases you may need to remove burrs or excess paint from inside the hole in the trigger frame, otherwise it may fit too tight to engage with the trigger, this is almost always required for the PCP pistols mentioned above. This process is shown in photos 3 and 4, more info on this in the next paragraph.

 For the PCP pistol models mentioned above there's generally two things that need to be done for the safety to fit and work smoothly, especially if using our custom aluminum trigger cover. First, the safety hole in the trigger-frame needs to be deburred and smoothed-out. We use a 2" x 2" square of wet/dry 300-600 grit sandpaper rolled into a very tight tube, sometimes it needs to be made from a smaller square depending on the thickness of the sandpaper. You generally only need to spin the sandpaper tube, as shown in photo 3, a half-dozen times in each direction, let it expand to fill the hole snugly, keep it straight and use light pressure. You just want to reduce any high spots and burrs, not enlarge the hole. The hole in photo 4 looks well-reamed but very little material was actually removed, it had very little paint in it to begin with, just a slight burr near the outer edge of the hole. Second, use the same tube of sandpaper to round-over the sharp edges and flat spot on top of the trigger where the safety engages it, this is shown in photo 5. The trigger and safety if installed correctly will fit snug together, work smooth and when the safety's engaged there's absolutely no trigger movement front to back, slight movement is ok also but there shouldn't be a lot of slop. Do a minimal amount of fitting in these two areas, then try the parts for function before working the frame and trigger more. The parts will generally work fine if they fit a little loose but most prefer they fit snug with no excess trigger movement when the safety is engaged. If severely over-worked the safety may not work reliably.
