I've shot both quite a bit, in a lot of different conditions. I currently own four 1911s, no glocks. Glocks may be a bit more reliable out of the box, on average. However, all of my 1911s run flawlessly, are more accurate than the glocks I've shot, mostly due to the trigger. I've even shot my 1911s with 3-400 rounds or more between cleanings, with no issue. I used to have an auto-ordnance that I tried to make quit by not cleaning. I gave up after 1500 rounds of cast bullet loads. (H&G 68 SWC and 5.0 gr. W231 IIRC) I'm pretty sure JMB had my hand in mind when designing the 1911s grip, too. Hard to find a more naturally pointing gun for me. Glocks, not so much. The grip angle is too steep for me. Put me in the 1911 group.
