I followed instruction video from mixup98 on disassembly of early release AMT back up. Not familiar with this model but am mechanically inclined. Attempting to troubleshoot jamming issue, which I have found with research is likely use of hollow point ammo. Anyway bolt is very tight fit in frame, looked much easier in mixup98 video. When bolt did release, ejector, firing pin and springs all came out. Wondering if some light filing should be attempted to ease fit of bolt in frame and if loose retaining pin of ejector should be overlooked, will stay together once reassembled I assume. BTW, magazine is aftermarket, original lost by previous owner who bought.380 back up new around 1979. Guessing on jamming issue that full jacket shells will correct problem ( suggested by mixup98 that AMT discouraged use of hollow point in back up). Any input appreciated. smithrlaw.
