My glock mags are the limiting factor for me 1.150 OAL so i load everything to that length. Works great in my 1911, M&P, XDM, and of course Glock. I have also used 1.135 with the same result. Im sure I could fine tune the loads for the guns but I didn't find the need. They all feed reliably, have the level of accuracy I want, and its way easier than having to keep track of what 9mm ammo goes with which gun. The only exception to this is that I try to make my 9mm Major look as different as possible (OAL and I used Hollow Points) to avoid any mishaps.
