People will have wildly different advice for you on which of those guns is best. They have very different ergonomics and triggers.

If you haven't fired a 1911 and a Glock before, you need to go to the range and rent a 1911 and Glock. I guarantee you'll know which you prefer after shooting both, and might like both for different reasons.

If you The DW will have much tighter / precise tolerances and a lighter, super glassy 1911 trigger. That means it will feel tighter, will be more accurate (triggers matter, a LOT), but will be less reliable if you get it dirty, and won't run as long (closer metal tolerances and less forgiving when dirty).

The Glock is looser, less accurate (although you have to be a good shot for it to matter), will have a heavier, very different trigger with an integrated safety, but will be more reliable and always go off. I mean like swim through a swamp and fire it after being underwater after a few seconds and fire another thousand rounds without cleaning it always go off. Glocks are indestructible plastic workhorses. Really great work guns.

I'm a huge Sig fan. I think metal Sigs are a good compromise between 1911's and Glocks. Still, I'm also into double stack pistols.

I'm holding out and hoping Sig puts 2+2 together and releases the P227 in 10mm, hopefully with an extended mag, suppressor sights, and a threaded 6" barrel. That gun would sell like snowcones in hell.
