This custom cover is machined from 7075-T6 aluminum, one of the strongest of all commercial aluminum alloys, stronger than many types of mild steel and stainless steels only much lighter. 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 Crosman part number 1322B044. It will not replace the older die-cast metal covers that only have two mounting screws 1322A044.
To fit Marauder Pistol, 1720T and 1701P, especially if using one of our custom brass or aluminum safeties, you will need to do some slight fitting as described below. This is due to the trigger in those PCP models fitting slightly different and not being as nicely finished where it engages the safety.
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.
