Initial Review on Sphinx SDP Compact Alpha

What interested me about the SDP family as opposed to the hand fitted earlier models? First of all, it's the construction: steel slide, aluminum alloy upper frame and plastic lower frame - the trifecta. Other SDP Compact families also feature a steel frame for those who prefer an all-steel pistol, different coating colors, threaded barrel, etc. However they're pretty much the same - still a design influenced by CZ-75. The difference is that the SDP so far only has a decocker similar to the CZ-75BD.
Too bad they didn't go all the way and offer a safety that can act as either decocker or cock & lock. Or offer a cock & lock version.

When it comes to aesthetics and ergonomics, I'm subjective just like most people. Ergo, these are my observations based on my preferences and expectations.

Pros:

Great fit and finish (the physical vapor deposition titanium aluminum nitride finish is about as pretty as an industrial type finish can be made - easily matches the P210 Legend in appearance and consistency), nice smooth DA trigger and crisp SA trigger (after the long take-up but it's a traditional DA/SA pull so it is what it is), clear and easy to acquire sight picture, takes CZ75B full size mags, weird triple material construction of steel, aluminum alloy and plastic, doesn't feel top heavy like many of the plastic framed guns.

Cons:

Slightly hefty (not heavy but not a lightweight either), wider slides & frames than necessary. I understand that the Compact's width is pretty much fixed by the existence of the rail itself, but the upper portion of the slide is quite blocky. I'm sure that if Sphinx were to slim down the slide, they could shave a couple of ounces off. Didn't feel a big difference when replaced the stock medium grip insert with small insert, if anything I would have preferred the small insert to have a flatter back strap instead of the hump on the current insert. Recoil spring and hammer spring are definitely stout. Eat up your Wheaties, boys. Probably not friendly for an average woman who has weak arms. Another weird design is that the rear sight is raised off the slide by probably a millimeter or two. Instead of sitting flat on the slide, you can see day light between the slide and the bottom of the rear iron sight - this happens on both Compact and Subcompact so I don't think that it's bad manufacturing.

The box is a nice plastic box with two grip inserts (Small & Large), a glossy operator's manual, a mag loader that looks like Glock mag loader, a cleaning kit, a bag of dessicant, an extra mag (though there is another slot for a 3rd mag) and a spring clip thingie to help pull the grip insert off the frame.

I'm sure you guys are saying to yourselves, "yeah, yeah, whatever, how does she shoot?"

She shoot good, kinda, sorta.

Mechanically she shoots fine, but I'm having a bit of a learning curve with her when it comes to precision shooting. Me and the sight picture - we no likie each other too much. The rear notch is wider than I would prefer and I find it tough to align the sights for precision shooting. I'm sure that with some more blasting, I'll get used to the wide rear notch. Great trigger pulls. On Mozambique drills, I can't tell which shot is from the DA first shot and which shot is from the SA second shot. SA pull is crisp and clean.

I need to round up some hollowpoints and see how she'd feed them as well.

Note the gaps between the bottom of rear sights and slide tops. Mags have both calibers and models marked on the bodies. Nice touch. Looks like Mec-Gar mags to me. Stamped "made in Italy" and have the smooth black anti-friction finishes that Mec-Gar had been putting on lots of their magazines.

For some reasons, I kept anticipating and threw off the first shots for several of the groups. Also, my sight alignment kept favoring to the left as well. When I pay extra attention to center the front sight on the wide ass rear notch, she'd shoot to point of aim.

I was getting disappointed with my 7-yds groups until I slowed down and paid extra attention for the 4th group. After seeing a decent turnout, I shot a 10-rounds 5th shot group that wasn't too bad. I played with Kentucky windage a bit and got two distinct 5-shots groups with the 10-rounds.

At 10-yds and 15-yds the shot groups really opened up because I'm not keen on the sight picture AND I was pretty darn upset with the Subcompact's malfunction issues - definitely didn't help. But to redeem myself, I borrowed a buddy's Ruger Wiley Clapp GP100 to double check myself.

Mozambique drills at 7-yds and 10-yds aren't too bad but I kept pulling the shots to the left a bit. That's me and not the gun. Nonetheless, with a slightly narrower rear sight notch, I think it would have helped me centering on target more. My buddy who lend me his Ruger really enjoyed the wide rear notch and it shot dead on for him. Different strokes for different folks.

I finally had the chance to take mine out yesterday. LOVE it. I agree that it takes getting used to when you're frequently shooting striker fired, but I have several other hammer guns so I don't think it'll take to long to get the hang of it. I also had some problems with the sight picture, but I believe I will resolve that once some fiber optic options come out. Also, while it's nice and smooth I don't really care for the double action. I have purchased the CGW spring kit for it, and I hope it fixes this for me. Other than that I encountered no issues with the gun and I think I put about 250 rounds through it.

First group in the green at 20 feet. Then I started shooting faster and it's obvious I lost the shot grouping on it.
I already posted a picture in the Latest Handgun thread, but here it is with it's cousin (P07 Duty)

I took mine out yesterday as well and had the same failure in my SDP Compact the OP reported about his Sub-Compact. Round stuck in chamber with the slide locked back, failure to go into battery. Ironically it was on the eighth round just like the OP. Emailed customer service and we will see what they do to fix this issue.

Appreciate the report. One of these caught my eye at a LGS while I was waiting on approval of another pistol I was buying at the time. Have been researching them since. Might be one in my future. Keep us updated.

I know this is reviving the thread, but there is news of some aftermarket sights finally coming our way. A cool company named ZRTactical is going to be selling some fiber optic sights. I'm not sure if they're a full set, or just the front sight. They also have some cool +3 basepads, which work fine for me. Hopeflly we'll get some night sights soon too.
