A note about 1911's. They originally had flat a MSH. During WW-1 many complained about the gun not pointing well and shooting low. Extensive military testing found that most felt the gun pointed more naturally and shot more accurately with the arched MSH. The military changed to arched in the 1920's and left them that way until they were replaced in 1985. A 1911 with the arched MSH has a grip angle very similar to the Glock and with the hump. Glock actually copied the grip of a 1911 with the proven arched MSH.
Using a flat MSH is a fairly modern change which helps make the gun point a little better for slow fire accuracy shooting. The Glock and arched MSH 1911's point and shoot better for rapid fire combat shooting.
