Where can you get a manual for American arms inc px 25?

Sorry, do not think you will get one. If my references are correct, just over 1,000 were made in 1990, 10 yrs later, they closed. The pistol SHOULD field strip much like the Walther pp. Remove magazine, clear the pistol by drawing back slide. Let slide go forward, pull down on front of trigger guard. Hold guard down. draw slide back, tilt, lift slide off the frame.
