The 4140 pre-hardened steel barrel with QPQ nitride finish provides corrosion resistance and hardness without adding weight. The aluminum frame with hardcoat anodize is more durable than bare aluminum and lighter than steel. PVD coating on the slide is more wear-resistant than standard bluing. ## Usage Scenarios At 29.06 oz and 7.4 inches overall, the SDP Compact sits in a useful middle ground: compact enough to carry inside the waistband but holding 17 rounds, which matches full-size capacity. It suits duty use, home defense, and range work. For competitive shooting it is less commonly seen due to limited aftermarket support compared to dominant platforms. ## Frequently Asked Questions **Q: What caliber is the Sphinx SDP Compact Duty?** A: It is chambered in 9mm (9x19mm Parabellum). **Q: What brand makes the Sphinx SDP Compact Duty?** A: It is manufactured by Kriss, with the Sphinx SDP Compact Duty Black made in Switzerland. **Q: What is the barrel length of the Sphinx SDP Compact Duty?** A: It has a 3.7-inch barrel. **Q: How many rounds does the Sphinx SDP Compact Duty hold?** A: It has a 17-round capacity. **Q: What type of firearm is the Sphinx SDP Compact Duty?** A: It is a compact DA/SA hammer-fired pistol with an aluminum frame and a PVD-coated steel slide. **Q: Does the Sphinx SDP Compact Duty have an ambidextrous decocker?** A: Yes.

The Swiss manufacturing and the materials specification get direct credit; owners describe it as feeling more precisely assembled than comparable pistols at similar price points. The aluminum frame and coated slide hold up well through regular use. Shooting feel is generally positive. Recoil is mild for a compact 9mm, which the low bore axis from the CZ-derived rail system contributes to. Accuracy at range is cited as a strength. Ergonomics are well-received, particularly the grip insert system, which solves fit for shooters who find most factory grips too large or too small. The most common criticism is availability. The Sphinx brand is not widely distributed in the U.S., which makes finding holsters, magazines, and service options harder than it would be for a Glock, SIG, or HK. Price is the other consistent discussion point: it sits above mainstream alternatives, and while most owners consider it fair for the quality, it narrows the audience. The aftermarket parts ecosystem is thin compared to more popular platforms. ## Pricing **1 offers available** | Vendor | Price | |--------|-------| | Gunbuyer Com | $913.41 | ## Similar Products - [Kriss Sphinx SDP Compact: 9mm Duty Pistol, 17-Rd, Black Finish](https://gunsnation.com/p/kriss-sphinx-sdp-compact-9mm-duty-pistol-17-rd-black-finish/UCEGPPyYp) - [Kriss Sphinx SDP Compact Alpha - 9mm, 15+1, Dual-Action Pistol](https://gunsnation.com/p/kriss-sphinx-sdp-compact-alpha-9mm-15-1-dual-action-pistol/UCEGPPxre) - [Kriss Sphinx SDP Compact Alpha - Precision 9mm Pistol, 15+1 Rounds](https://gunsnation.com/p/kriss-sphinx-sdp-compact-alpha-precision-9mm-pistol-15-1-rounds/UCEGPPyMl) - [Kriss Vector Gen II SDP 9mm Pistol - 17+1 Rounds, Super V Recoil System](https://gunsnation.com/p/kriss-vector-gen-ii-sdp-9mm-pistol-17-1-rounds-super-v-recoil-system/UCEGPPyak) - [FN 509C Compact 9mm Striker-Fired Pistol - Matte Black Precision](https://gunsnation.com/p/fn-509c-compact-9mm-striker-fired-pistol-matte-black-precision/UCEt9uJ8c) - [Kriss Vector SDP Gen II 9mm Tactical Pistol - OD Green/Black 17+1](https://gunsnation.com/p/kriss-vector-sdp-gen-ii-9mm-tactical-pistol-od-green-black-17-1/UCEGPPyay) --- *Data from [GunsNation](https://gunsnation.com)*
