To add one more even though i kind of think what the heck for ... Sprinpfield is offering a 1911 in 45 gap now so it will have a small grip all the way around that the 45 acp might also be something you might be intersted in if you dont mind using a Ego Round

Oh that's right...we should soon be seeing even more firearms hitting the gun shops chambered for the .45 GAP.
That should bring the front to rear grip size down quite a bit while still keeping a .45 punch.

According to springfield 1/8 smaller grip

That is a good choice
