Mine had all the CGW bits and I've done a bit of polishing. With the cgw guide rod and 13 lb recoil spring, it doubles. With the stock recoil spring assembly, it doesn't. Go figure. I like the gun quite a bit and prefer it to the sp 07 I had and gave to my son. But, I have to admit, I like my M&P 2.0 full size 4.25" barrel more. The smith fits my hand better, shoots softer, and has a better stock trigger. I shoot it better. I'm looking forward to installing an apex kit. Also, it reportedly fits in the IDPA box with slim base pads.
However, the steel CZs kick both of their asses IMO. There is something about a nicely tuned steel CZ, and I've got a bunch of them.
