Everything jams
It is a fact of life. Nothing is 100%. Fed quality ammo, most modern pistols have good reliability. 99.9999% is not unheard of, but can not be reasonably expected from an out of the box gun, especially since there is no way of knowing what ammo you are going to be using.
Think about it, manufacturers have to make their pistols work the majority of the time without having any way to control the ammo used, or the shooter's grip, or the environmental condition, the lube in the gun (or lack of it), etc.
Some guns manage very well. Others not so at first, then 'settle in". Some guns never seem to run right with some ammo. Others eat everything.
And the have to deliver this reliability at a rock bottm price, other wise people get on the internet and trash their product. "my expensive gun jams with the cheapest crappy ammo I can get, so it must be a piece of overpriced junk!" 90% of all the whining I read about reliability boils down top somewthing like this. Or, "it won't feed X brand hollowpoints, but works ok with Y brand, and FMJ.... "
I got news for you, no auto pistol designed before the 1950s was intended to feed hollowpoints. Not one. The fact that most do, and some do well is a bonus, but no basis for complaint if the gun doesn't. The 1911A1 got it's reputation for reliability using FMJ (ball) ammo.
Pistols designed later are still at their most reliable with ball ammo, but the designers have taken holliow point use into consideration. Most work, but some still have problems, usually more ammo related than any thing else.
You want a box stock 1911A1 to be reliable right from the get go? Get a milspec gun from a quality maker, and feed it quality ball ammo. It may not run perfect at first, or it may. Odds are it will. it likely won't shoot 2 inch groups, but it will shoot minute of man. If you want more, you have to bargin. Nearly everything done to "accurize" the 1911 also has the effect of reducing the reliability in less than perfect conditions.
If you want a gun that is "broken in" to the point of assured reliability, you can't call it a new gun. And if you expect a factory or custom shop to provide you with a gun like that, expect to pay for it.
The electronics industry has spoiled consumers, led them into thinking all products should work like electronics, either perfect function, or serious failure, right out of the box. Machined products of all kinds require a "break in" period, before reliable operation or consistant failure can be determined. And when you add in the tremendous amount of variables with guns and ammo, it is unrealistic to expect perfection. Be happy when you get it, people get it alot more often than they should, considering everything involved.
