To remove the cartridge pin from the cartridge stop on a Savage 745B shotgun, first ensure the firearm is unloaded and safe to handle. Use a small punch or a similar tool to gently tap out the retaining pin holding the cartridge stop in place, being careful not to damage the surrounding components. Once the pin is removed, the cartridge stop can be taken out for maintenance or replacement. Always refer to the shotgun's manual for specific instructions and safety precautions.
The 745b was made between 1940 and 1949.
Mfg. 1940-49
The value of a Savage 745b in very good, clean condition is around $300 retail. These are excellent shooters, as I hunt with one every year, and are a close copy of the auto 5 Browning. They don't have much collectability, but are one of the best hunting shotguns you can have, due to their lightweight receiver. Auto 5 parts won't interchange, but you can get replacement parts through Gun Parts Corp.

To disassemble a Springfield 745B, first ensure the firearm is unloaded and the magazine is removed. Next, pull back the slide slightly and locate the slide stop lever; push it out from the left side of the frame. After removing the slide stop, carefully slide the frame forward off the slide, then remove the recoil spring and barrel from the slide. Always refer to the manufacturer's manual for specific instructions and safety precautions.
Depending on the condition of the gun between $275.00-$110.00.
