Got my EVO last year and had lots of fun with it, even as just a "pistol".
Then got a brace, and my enjoyment went up dramatically, along with accuracy. It became really obvious why you need the stabilization. Although the brace worked OK, it just didn't look right; it didn't fold; and didn't fit in the EVO case.
So I got on the waiting list for the first SBR kits, which took months to arrive. But not as long as my tax stamp, which took 10 months, including the "correction" that I was asked to make..
Put that all together, and am VERY satisfied because it all looks and acts right, as CZ intended, and fits perfectly in its case. Yes, I paid more than some might have (and EVO prices have come down a lot recently), and the difficulties of taking it out of state make it more complicated, but I've gotten amazingly fast turn around from ATF on those forms via e-mailing them in.
It's a 2-stamp affair, but I haven't yet had time to try out one of my suppressors with it yet. I am expecting the fun to go up another notch when that happens.
