They have become very popular because of their presence in the many forms of "action" shooting. Other such accouterments have become popular on shotguns and rifles for the same reason - we see them being used in competitive shooting. But, well, what gives one an advantage in competition, be it shooting, automobile racing, or whatever may very well prove to be a hindrance in "real life".

I call these things in their many guises "range guns". I'm glad to see that HardDrive plans to use it as such. Their many advantages and disadvantages have already been highlighted by others. I've noticed all of the advantages mentioned are only advantages at the range. We need to be careful if we wish to transfer these "range gun" advantages to the field, be that out in the wilderness elk hunting or on the streets prepared to defend ourselves. I've seen way too many things that just don't make that transition. I put optics of any kind on a defensive handgun in that category.
