There is very little that one can tell about over pressure in handgun ammo. Kinda like reading tea leaves, Usually the only tell is a major failure!!. You can not read primers. Some revolvers perhaps hard extraction but in a semi, not so much.

Even though you may not be using Accurate powder they tested the same bullet and see what there COL is.

Flat nose or similar HP bullets are going to be shorter than a typical longer nose 9mm bullet, The pointy end of those bullets will fit the barrel better than a short fat profile.
