Retired, will mail the mag today USPS. If you are unfamiliar with the R9, there is much good advice available here. There is a thread that details much you need to know, but I can’t find it....someone here will provide. Briefly, take it down and clean it before shooting. If you have no manual with it, pull it up on-line. The “Pup” likes to be well lubricated and clean. The recoil spring needs changing every 200-300 rounds depending on ammo used. Do not use “hot” ammo, +P, etc. Some ammo has hard primers, avoid! It likes a firm grip. The grip screws tend to loosen after 20 to 40 rounds. If the right grip gets loose, the trigger bar doesn’t function....BUT do not over tighten or you will strip the threads. Avoid Loctite, same reason.
This is absolutely the most comfortable carry 9mm piece you will ever experience. Enjoy!
