Read up on good old Elmer Keith and Ed McGivern.
Long range handgun shooting has been around along time.
And then go to a IHMSA match and see what can be done off your hind legs with a handgun.
And yes, at 100 yards with my Kimber Gold Match .45 putting all the shots inside a IDPA target, standing, firing two handed, I've done many times. I pack Glocks but I know a accurate 1911 will outdo it as for as accuracy.
