glocks are ugly, have no soul, and the company owner is a major POS who cheated his own family out of millions. I will never buy a new one, and I won't own a used one for longer than it takes me to trade it.
Good 1911 pistols require no "tweaking" to run correctly. They may, however, need a few hundred rounds to wear in the parts, which I do anyway with any CCW that I buy.
glocks generally don't need this, as they are deliberately made to slack tolerances, similar to AK rifles, which also suck and are ugly.
All that may be true but any stock Glock will have a much less percentage of failures compared to any stock 1911. I would also be willing to bet that a known Glock would fire a lot more rounds without any mishap,than any known,custom or whatever 1911. My little 36 has never in nearly 20 years failed to go bang when I pulled the trigger.
