feel is relative, fit is not. Fit refers to the grip size and not the grip angle/feel of the gun.
Grips angles and controls are things you CAN learn to shoot and get used to, between different guns, but a grip that is too big for your hands is TOO big, hence, you are handicapping yourself.
Grab the gun and see where you index finger falls and how it wraps around the trigger, this might feel OK for everygun for the first 10 shots, but when you shoot 100 in a row you will feel every bit of awkwardness if the fit is wrong.
Slide releases, hammer, magazine release, those are thing you anyone can adjust while breaking your grip (re-adjusting you grip means that at that point you cannot shoot, something that in a combat situation might cost your life).
So, FIT is not BS, fit is real. Buy the one you like for looks, but you will be a better shooter if your hands wrap around the grip naturally, why fighting the beast when there are so many others already domesticated...
Cheers.
