I have the SPD DUTY. It's the all alloy frame, 17rd magazine. It's been absolutely flawless. From what I was recently told, the Swiss made guns will no longer be imported. So for anyone who's reading this, if you want one, I wouldn't put it off too much longer. The new models will
be manufactured here. Out of the box, everything on my Sphinx was tight. The slide was tight, the decocker, slide release, hell, even the magazine catch. For the most part, and after about 800 rounds, and several cleanings, the controls are much easier now. The finish is outstanding, and
the gun still looks brand new. I've owned multiple CZ's over the years, along with pretty much everything else like a lot of you, and I have to say, my Sphinx has become one my top favorites. I love owning this gun, and I'm seriously considering purchasing another. I haven't read too
many negative things about the SDP, just "I heard this, or I read that" but very little information. I cannot comment on the CS at KRISS, as I've had no reason to contact them. Someone mentioned the barrels, and from what I know about them, they are
very similar to the Glock. Hammer forged, polygonal, even though Glock is going away from that on the GEN 5 guns.
