Maybe,but anybody who is serious about shooting needs to reload,and not all autoloaders feed wadcutters real well. This isn't a problem with a revolver,and a wadcutter is a MUCH more effective bullet than the RN acp load. Yeah,I know about hollowpoints,but my theory is start with a big enough bullet,and then put it where you want it.
The above said lets face it not everyone not even a majority of those who carry for self defense will be reloaders. Reloaded ammunition is great for practice but God help the person in an anti-gun state with an anti-gun prosecutor who uses hand loads in a self defense situation. "Ladies and gentlemen of the jury. Not only did this person shoot this poor disadvantaged youth but he was not satisfied shooting him with the deadly ammunition available over the counter he had to make up his own even more harmful ammunition....."
Now, a factory hollow point has the advantage that it can be argued to the jury. "The defendant was responsible enough to pick ammunition that would not over penetrate and even went to the trouble of getting the same ammunition used by _______ police department." Is a .44 spl wad cutter a better stopper than a .45acp hollow point? I personally would be satisfied with either. It a Charter Bulldog pug a good self defense sidearm? Most certainly. Is a model 1911 .45acp a good self defense sidearm? Again most certainly. Is the ammount of practice one gets with a sidearm more important than caliber choice? IMHO again most certainly.
My usual choice of sidearm is a .45acp semi auto pistol with a ten round magazine. Is this for everyone? Certainly not.
