New SP-01, unusual finish wear?

[capntang]

I bought this pistol in late January of this year, and I've put less than 400 rounds through it.  While cleaning it last, I noticed a spot on the bottom inside lip of the ejection port where the finish appears to be cracking or flaking off.  I can't say I've ever seen a pistol exhibit this kind of wear after less than two months, three trips to the range, and well under 400 rounds.  All the pistol has seen is first-run, brass-cased ammo, so steel cased rounds aren't to blame.

I've attached a photo of the slide below (click for larger view).

Is this normal for a CZ?

Well Cap'n we're at the same point. I have around 300 rounds through my new shadow and see absolutely no wear at that point. Can't offer any insight but only can share similar usage. I'll take a phot if you like

Good to hear.  I've heard from a few other CZ owners on another board, and none of them reported this kind of wear.  Sounds more and more like I may have some sort of defect on my hands.

I fired off an email to the gunsmith at CZ, and his suggestion was to clean it with bore solvent.  He seems to think it's brass marks.  I thought it was clear enough in the picture that the lighter colored spot is actually a recessed section of bare steel.  I responded, so we'll see what comes of it.

How do you like the Shadow?

They're OK I guess.

well as mentioned I'm just into the first week with it but managed to get out 3 times so far. It has great ergos for my tree stump fingers and being a lefty the controls work well for me. I'm certainly very happy with my choice.  -now to just find more shooting time
Keep us posted on the results of your email Cap'n

i have the same wear on mine, maybe even worse. i get bothered by it once in a while when im not shooting. try shooting the gun more often and you'll forget about all the wear and fading in your gun =)

I have the same wear on my low round count SP01 Phantom.  I do not mind the wear so much, but the gun was also consistently ejecting brass (softly) on top of my shooting hat, which was very, very annoying.  If a pistol ejects brass hard towards your head, it can be because the brass is being ejected too vertically.  But in this case the brass was coming back softly.  The markings on the lower inside of the ejection port were a clue that the brass was ejecting too laterally, bouncing off this portion of the ejection port, and then kicking up and back at my head.  The brass was not bouncing off a near wall, as I did testing in an open area too.  I thought of lowering the port like one would on a 1911, but did not want to risk weakening the slide.

I solved the problem by reshaping the tip of the ejector (NOT the extractor).  Note: I did not change the lateral profile of the ejector tip, which slopes down towards the trigger.  After field stripping and covering the small moving parts with paper towels, I gently filed down the left sided point on the ejector so it was more square when viewed from above.  I wanted to change the angle of the ejector tip so the case would be struck less at the far left edge.  This was all I needed to correct the ejection angle and now the brass ejects cleaning off to the right side.  No more annoying brass landing on my hat.  The finish wear on the inside of the port does not bother me and was the major clue to solving the problem.  I may have my gunsmith touch it up with a spot of Duracoat, but it really does not bother me.

The real question is whether or not your brass ejects cleanly or at your head.  If the brass comes back at your head, think about reshaping the ejector tip.

Got the same wear on my Tactical. I know it's not a big deal but it still bothers me a little bit.

WildRice, can you post photos of what you had done as I'm new to this and do not want to mes up my CZ.
Thanks.

After I adjusted the tip of my Phantom's ejector and corrected the too lateral ejection, the brass now ejects cleanly off to the right (clearing the lower right edge of the ejection port) and no longer bounces back at my head.  To refinish the scuffed edge of the ejection port I used a Birchwood Casey Super Black (flat black) touch up pen.  I did this mainly to see if brass would rescuff this part of the ejection port.  Sure enough, after a few boxes of test firing, that area is now scuff free, meaning the brass is no longer hitting it.  Unless you correct the ejection angle, refinishing won't do much good.

I noticed that the right ejection port wall is significantly higher on my Phantom than on my P-01.  That is part of the problem.  I was at first tempted to perform a port lowering job like one would on a 1911.  However, I figured that tuning the ejector tip would be simpler yet still fix the problem.  Turns out that was all it needed.

The black on black photos did not turn out well.  When viewed from above, my stock ejector tip had a forward edge on the left side that was hitting too far on the left rim of the casings and kicking them too laterally to the right.  I filed down this left edge so that the ejector tip is now more square when viewed from above.  I removed a little less than 0.5 mm of metal.  When viewed from the side there is no apparent alteration as the ejector tip's downward slope towards the mag release button was unchanged.
