It is my understanding also that short barreled .45s will not produce the velocity necessary for typical hollow point ammo to expand with a few exceptions (the Hornady Critical Defense & Speer Short Barrel). These rounds are specifically engineered to open up at slower velocities. Another alternative when using a shorter barreled .45, is to use a lighter weight round (185 or 200 gr) loaded in +P. In my humble opinion, if you are carrying a .45 with a barrel of 4 inches or less, ammo selection becomes extremely important.
