The Unofficial P64 Resource Forum

It happens either way - putting in a magazine or letting the slide run forward. If the safety is engaged it's like something is rubbing against the slide causing it to not fully return to battery. I usually keep my safety on and if I load a magazine and pull back the slide it always causes a jam.
