1911's are combat and competition proven, and as stated by danf_fl, the performance of any firearm depends on care and maintenance. Magazines are a big factor in how a semi-auto performs. Avoid cheap "gun show specials," and stick with major after market brands.
Another factor is ammunition, but most 1911's with quality magazines will feed most ammo.
Once upon a time, the 1911 was king of the hill in competition, and some major league shooters still use them.
