Well, I am sure it is part 'cult' and mostly habit.... but 'back-in-tha'-day' when 1911s weren't what they are now, there was a huge number of combinations of feed ramp types, recoil spring weights, mag types/brands, mag springs, feed-lip styles/adjustment - plus all the ammo stuff - weight, shape, OAL, etc, etc... if one could find a set-up that would reasonably feed inter-mixed ball, JHP and different brands/bullet shapes, one had a higher level of comfort that such a set-up would tolerate the lesser variations
within a chosen single ammo type. I realize that a lot of this may not be very applicable to the 'pups' and auto pistols in general these days, but habits die hard

- and I certainly don't see any real downside... the fact that
MY single gun doesn't seem to like one particular choice, while three other options work fine in it, is hardly a indictment of the gun or that ammo. It's all good
