My LGS called about a new arrival-a Sig M400 pistol. I generally prefer the cleaner operation of a piston system (SIG 556) over DI (M400) However, the M400 weighs about .8 pounds less than the SIG 556. Any thoughts or experiences with either weapon?
I have the Sig 556 pistol. I like it. Some people hate them. It's not on par with the actual Swiss guns by any means. But it is fun, reliable (at least mine is) and easy to strip and clean. It is fairly heavy.
