The crimp on an auto pistol round does nothing more than remove the bell that you put in case to allow the bullet to be seated,nothing more.. Your sizing die,if correct,places enough
case tension to hold the bullet in place for correct function..
A heavy crimp,taper,will generally cause a loose bullet and create a dangerous situation..Bullet set back on chambering..This can and will raise pressures to dangerous levels..Just asking for a
KABOOM..
