I have one in 40. The 9mm is cheaper to feed.
My employer is changing over to this pistol in 2007. I like to own the same as I carry.
Similar to a glock, this is definately not a Sigma. I have only put 300 rounds through mine. I find it easy to shoot, but keep in mind that it is not a target pistol.
At combat distances, it can keep everything in the A-zone easily.
It will not do the same on a 25 yard bullseye range.
If a major police service adopts it, it will take off faster.
Mags are cheap for it right now, and S&W is really pushing the pistol.
