I had one (sold it), and it was too bulky for concealed carry. If you are in an area where you can open carry, the weight would not be a problem with the proper holster and gun belt, but (for me) it would be too big for concealed carry other than under a heavy coat during winter.
If it is for carry, I'd go for a gun without the light rail. 1) finding holsters are more difficult 2) it adds more bulk 3) you can't conceal carry with a light attached 4) if you just want a laser, get Crimson Trace grips.
IMHO, light rails on a pistol are for home defense guns (even though a shotgun would probably be better than a pistol) or military/police usage.
