Well, I finished the slide, as one of the links above indicates, made it to a range a few times to get the last few bugs worked out and the sight zeroed, and took it to the opening match of the USPSA season at Castlewood Rod and Gun Club, our favored approximately-local destination for low-pressure shooting sports1. How did it go?
The most pressing issue discovered in testing was that the .40 S&W magazine bodies do not actually feed 9mm reliably. They appear to, and work most of the time in testing, but I ran into some issues where the last few rounds would cause trouble. The second-to-last round would sometimes pop up beyond the feed lips to make a stovepipe failure to feed, a very unusual malfunction.
There was also an issue with a wimpy sear spring causing hammer follow, but I took care of that last year at the end of the Limited season.
The first order of business was getting the sight zeroed. This turned out to be much less drama than I had expected. Parvusimperator and I popped over to our local indoor range, and while he did some drills, I set about adjusting things. Between my ballistics calculator app and my surprisingly not-rusty pistol skills, I got to a reasonable 25-yard zero pretty quickly. It shoots about an inch low at the sub-10-yard ranges you find most USPSA targets at, but is much closer to dead on for the 15-25-yard long-range targets, which is where I’d prefer the sight be the most accurate anyway.
On the second trip, in the middle of the week before the Saturday match, I did a bit of zero-refining—the point of impact was a bit to the left of the point of aim—and ran a printed-target drill parvusimperator brought along. This was also when I discovered the magazine issues mentioned above, happily leaving me enough time to pop the followers and baseplates off of the .40 magazines onto my 9mm magazines.
At the end of those two practice sessions, I was feeling fairly confident. Dots are pistol easy mode, and although I felt I had some work to do in picking up the dot on the draw, I was happy with the performance of the gun and my performance with it.
The Match: How I Shot
In short, pretty well! Finding the dot did not prove to be an issue on the clock.
On the first stage of the day, I discovered I had not screwed my battery cover in tightly enough, so the cover and battery popped out mid-stage. It was in one of Castlewood’s small bays, fortuitously, so I was able to point-shoot my way to the end with no misses. Someone found my battery cover in the mud, but not the battery, and since I had neglected to bring extra batteries2, I had to bum one off of someone else.
After that, the drama was limited. I ended up putting in stellar performances on the next two stages, good enough for the Carry Optics stage wins. I dropped some points on the classifier for taking an extra shot, too.
The gun performed perfectly, and having 23 in the magazine makes stage planning even easier than having 20, like I do in Limited configuration. I was able to complete several stages with no reload; Castlewood frequently has short stages mixed in with the long ones, which I appreciate both from a variety perspective and from a costs-less-in-bullets perspective.
The Match: Results
I was 23rd overall out of 60-some shooters, and 2nd out of 6 Carry Optics shooters (within 6% of the leader, too!). I won two stages in Carry Optics, like I said—one a moving-heavy stage with some restrictions on target engagement, one a shooting-heavy stage with a reload.
The classifier for this match happened to be the same one I shot to wrap up last year with Limited, so I can make some direct comparisons. I was a little slower this time out, in part because of penalties, and in part because of some rust on my classifier draw-and-shoot skills. Going by percentage of As shot, I was much more accurate with the Carry Optics gun, and just about as fast. I won’t know for sure until the next match, where I plan to swap the slide to get both divisions in the same day, if I’m faster with Carry Optics or Limited, but it’s definitely close enough to be in question.
I’m entirely satisfied with the outcome. I beat the shooters I was supposed to beat (those in the Lesser Divisions like Production), nearly won my division, and came out ahead of a few Limited shooters who are usually a little better than me. I was the sixth-best non-PCC non-Open shooter at the match, which is the fairest group to compare me to.
All told, the CZ Carry Optics project is an unqualified success.
