While nowhere near the same weight, I have a glock23 in .40 and a springfield mil-spec in .45. Just from my experience with those particular two, the .40 is a much quicker, more pronounced flip upwards while the .45 is almost a straight back, much slower push. It's actually MUCH easier to shoot the fullsize 1911 quickly and accurately because of the direction it recoils. The slowness of the recoil may also make it easier for a slightly more novice shooter like myself to manage it and stay on target. I still shoot better with my glock, simply because I've put 2500 rounds through it since it was new and only 200 or so through the 1911, which is my first. I feel that the accuracy and capability in the 1911 will surpass the glock for me in time though. I had a RugerP95 (durable, nothin wrong with it but, man it's got no stlye!) that I just traded for an Arcus 94 (the hi-power clone). The P95 in 9mm was even snappier and harder to re-acquire target after shot than the mil-spec. The P95 is quite heavy as well.
Needless to say, I was pleasently surprised with the way the recoil on a full-size 1911 works. It's actually kind of comfy/nice to me. I'm hooked

I even changed my mind about using the glock in some competition stuff and now will be learning to shoot the 1911 for competition instead.
