I never understood it. I've only "customized" a couple guns in my life, and that was nothing more than making them mine. I have no intention of ever selling them so I did what I wanted. I have added accessories to guns such as optics, night sights, rails, etc. but never tricked anything out to the point of changing the gun altogether...If guys want to do that, more power to them, but they should not expect anyone else to fall in love with their handiwork.
As far as particular tasks go, if you're not in a line of work that demands specialized tools for the task at hand, you're simply wasting your time, money, and many times, your gun. Not entirely, of course, if that's what you want, but if you change your mind and decide to get rid of it, don't expect anyone to pay for it afterwards.
For the most part I don't even want a gun that has been tampered with internally. The work would have to be done by a sure enough pro that I'm familiar with, like Hook Boutin or someone of equal reputation. Otherwise I'm not interested.
