I don't like having to load mags, either. A fun, relaxing day for me at the range doesn't involve spending half my time stuffing mags. Spending $50 in some cases for one mag doesn't sit right with me either.
I also don't like worrying about mag springs, recoil springs, slide stops, etc. Relying on a 10 cent spring to push the rounds up and having to worry about fatigue on the springs is something I don't like to worry about.
I can shoot my S&W and Ruger revolvers forever and never have to worry about anything.
Some makers of auto pistols brag about 100,000 round service life for an autoloader, but this round count wouldn't even affect something like a 28,686,or Ruger GP100 if you fire mostly .38's.
