I have been shooting them for over 10 years.
As far as reloading, do not use lead bullets. The barrels are chromed lined and the lead will bind to the barrel, use jacketed bullets. Sounds like your will be a collector and not a shooter.
My current one is a 92fs. I had the frame nickeled. The barrel is bead blaster and hand lapped. The barrel lock has been worked to tighen up the barrel to frame. Polished trigger and sear. Recoil and trigger spring has been replaced to Wolf springs. Rear sight has been changed to a Mec-gar adj. Grips have been changed out to full wraps(big hands). This pistol has seen over 20,000 rounds an is still tight, and a tack driver.
As far as mags, I have used about every after market ones in the pistol without problems. But if you keep them loaded, you will have problems with the slide lock on the last shot.The springs on some take a set too fast.
I should note that I have changed the springs to Wolf extra power, and changed out the floor plates to factory ones. I "free drop" mags on reloads(match), and stack my second and third mag to the top(reworked followers).
P.S. Pull the slide apart every 10,000 rounds and clean the firing pin and extractor. There is a void behind the exstractor, and above firing pin and channel. The fouling won't stop the pistol, just slowes that lock time in regards to firing pin movement.
