Its preference. Most people love the way a flat mainspring (flat backstrap) points. I personally like it because it doesn’t require me to point my wrists as forward. It’s amusing that whenever people build Glocks with aftermarket frames or get heavy into modifications to the frame they often remove the heel bump so it points differently in the hand.
Think of all of the guns besides the Luger and Glock that have such an exaggerated grip angle or grip angle heel hump that have caught on massively…..not many. Meanwhile the Springfield Xd, SW MP pistols, 1911s, Sigs, HKs, high end Berettas like the M9A3, Canik, CZ pistols. Most people when they customize the gun extensively don’t usually choose to have a heel bump. Not saying that’s set in stone but many for a combat handgun don’t prefer it when they modify every part to make the gun tailored exactly as they want it. The heel bump makes the muzzle point more upward than a flat heel. Most people live with it but when they have the opportunity they often prefer to change it. Glock would sell a billion more pistols if they got rid of the heel bump, but they’re slow to catch onto what the market wants, unlike Ruger and Smith and Wesson.
With all that said the bump on the Beretta isn’t bad at all because it doesn’t come out very far. Here is what I’m talking about:
Attached File Attached FileThe Glock comes out back behind the frame and breaks the straight line of the backstrap. The Beretta doesn’t do that, so it won’t point as high as the Glock.
