An original stock 1911 or 1911A1 was designed to feed ball ammo. Modern commercial guns vary widely in quality; some will feed anything, others not so much.
A good gunsmith can make almost any 1911 hum perfectly with nearly any ammo.
For the home enthusiasts, I wrote an article in 2000 - "1911 Reliability Secrets." A larger version of it appeared in American Gunsmith in that year. These are the tricks that will make a 1911 as close to 100% reliable as possible. Most of these procedures can be done by anyone who is mechanically apt and is willing to devote some time and effort to doing them properly.
