I picked up a Bobcat 89SP yesterday for what I consider to be a smoking deal. I read up here first and understood that these have been known to have issues. When i loaded it and fired, it didnt pick up the next round in the magazine. This happened 5 times out of a box of 50. It has no problems vacating the chamber after it fires from what I can tell. when I got home, I cleaned the whole weapon (which seemed as if it may have still had the factory lube on it) and began to order parts based off of what I have read. I ordered a 9mm hammer spring, extractor spring, buffer spring, and a factory mag. I intend to replace the trigger group possibly, and get more mags before I am done. I'm curious if there may be any other recommendations of possible parts to replace while I am at it, and any suggestions on how to fine tune this weapon.
