I bought a pretty good P 1 from AOA. I opened the top to look her over and spied a small spring lying between the compression tube and the frame. It was lying there loose and no indication from whence it came. The rear sight looks like it could be for upward pressure but it works fine. Up- down, side to side there is pressure. It is smaller diameter than an ink pen spring and about one third the length. All seems to be in order and shoots nice. Cocking is smooth with both settings being obvious. Safety works. ? ¿ ? Perhaps someone was working on it and lost the spring when it launched. Or the original owner wanted me to have a spare? Any Ideas from guys that have repaired a P 1? Be Well Brothers, B.
