The Sphinx SDP Compact pistol was on display at the KRISS/Sphinx booth at the 2012 SHOT Show. The SDP is a 9mm pistol that is made in Switzerland.
The SDP Compact uses a traditional double-action/single-action system. The DA trigger pull is rated at 8.16 pounds, while the SA pull is around 3.3 pounds.
The frame is a little more non-traditional, as it has two halves: an upper aluminum and a lower polymer. The upper portion of the frame is hard-anodized aluminum, with full-length guides rails machined into the metal. The rails use Teflon inserts to help reduce wear.
