I have two 1911’s and I have never had one jam, with tens of thousands of rounds run through them. Buy good ammo - not the cheap crap. Federal makes good ammo. The same goes for magazines, which also need to be cleaned after use. Apply oil, then remove any excess. Don’t load and unload mags unnecessarily - the cycles of compression and uncompression will weaken springs over time. Store them loaded. Periodically, though: unload the mags and reload them in a different sequence. Finally, keep your guns clean and well-lubricated, stored in a cool, low-humidity location.
Wilson Combat mags are top of of the line.I use them in my 45s.
