My Springfeild will feed anything you shove in it, including many flavors of hollowpoints.
My Dad had a 1911 (not A1) that, with some tweaking, would hand cycle through a magazine of caseings.
I will say the only real fault we've had with our 1911 has been banged up magazines. And keeping the feed lips from getting bent up isn't exactly a real challenge.
When the question is "quick, here's a NIB 1911A1 and a NIB Glock, pick one and shoot!" I'll grab the Glock. (unless it's gen 4
)
But if it's "Quick, here's your Glock 17 and here's your 1911, pick one and shoot!" You bet I'll be grabbing my 1911.
The fact that a 1911 may require more induvidial attention from out of the box too daily carry does not negate it's overall practicality for SD.
