Fishbreath Shoots: CZ P-09 .40 S&W ‘C-Zed’ Race Gun Build

If you’ve been following us for a while, you may remember my two race gun proposal posts from last year, in which I justified my desire to build a USPSA Limited gun on the cheap.

You may also recall the shootout post, in which I decided that the gun to buy, between the Beretta 96 and the CZ P-09, was the CZ.

Lastly, you may recall the CZ P-09 .40 review from last summer, in which I reviewed the base model gun.

We’re now nearly to the end of the series. In this post, we’ll explore what I did to the P-09 and what supporting equipment I bought, and, at the end, come up with a cost.

Requirements

Beyond the requirements imposed by the USPSA Limited rules, there are a few requirements I gave myself, too.

  1. A decent competition holster, preferably something with drop, offset, and adjustable retention.
  2. At least 60 rounds of ammunition on the belt. That was my setup with the M9, and I didn’t want to go any lower.
  3. A sturdy belt to hold everything.

Internals

The C-Zed’s guts are all Cajun Gun Works all the way. I bought their hammer, with different spur geometry for reduced single-action trigger pull, the short reset kit, which included an extended firing pin, and a number of springs: a main spring, a reduced-strength trigger return spring, reduced springs for the firing pin plunger, and an increased-strength sear spring.

The increased-strength sear spring sounds like it’s the wrong tool for lightening a trigger, pull, doesn’t it? You would be correct. Cajun Gun Works sells them as a tool for adding weight to a dangerously light trigger. I didn’t expect to need it and didn’t use it in the end, but figured that, at $10, it was worth the money just in case.

The other items on the list all work together. The hammer reduces single-action pull, the main spring reduces the work the trigger has to do, the reduced trigger return and firing pin plunger springs reduce the spring weight you’re pulling against. The extended firing pin is necessary for the lighter main springs, because the reduced hammer impulse can cause light strikes.

I haven’t had any trouble with cheap Magtech ammo, though, with the full setup. All my primers are well-punched; none are punctured.

Everything was relatively easy to install except the trigger spring. It’s a coil spring with offset legs. The trigger has two ears and a space in the middle, and a hole for one leg of the trigger spring. You have to get one end of the spring in the hole, one end on a shelf, and the trigger ears and spring coil lined up with the holes in the frame for the pin, all while pushing the pin in. It was a four-handed job at Soapbox World HQ.

In the end, the combination of modifications resulted in a smoother 7lb double-action trigger pull, and a very crisp 2.5lb single-action trigger pull (albeit with the expected double-action takeup). Those are significant improvements over the stock 10lb double-action pull, and the stock 4.5lb single-action pull. There were also improvements in crispness, creep, and reset, thanks to the Cajun parts.

Sights

Cajun Gun Works sells Dawson Precision-made sights in traditional competition configuration: blacked-out rear sights, fiber-optic front. It comes with green and red bits of fiber, so you can pick which one you want.

These were the most annoying parts to install. The Dawson rear sight was tremendously oversized, and took about half an hour of filing before I could punch it into place. The CZ factory front sight had been glued in. Try as I might, I couldn’t even begin to loosen it. I ended up stopping by the Friendly Local Gun Shop, which has a much better heat gun; they got it in a few minutes.

Not to be outdone, the front sight from Dawson took some filing to get installed, too. Precision is not an accurate descriptor of the sights’ fit into the dovetails.

Magazines

Cajun Gun Works’ part in things completed, I turned to CZ Custom for magazines and magazine wells. The C-Zed now mounts the large CZ Custom magazine well, which makes a big difference in ease of magazine insertion.

The P-09’s magazines, with the CZ Custom 140mm base plates and spring-and-follower kits, have a claimed capacity of 21. Parvusimperator suggested I take that with a grain of salt, so I assumed 20. I decided I wanted four magazines rather than just three to give me more flexibility on reloads; at the same time, I was looking to keep the total cost of the project down. I settled on four magazines with the 140mm baseplate, but only three with the spring-and-follower kit.

The end result is three magazines which hold 20 rounds of .40 S&W, and one magazine which holds 17. The latter can be used to get a round into the chamber before loading one of the 20-rounders to start a stage, and serves as my backup.

Belt Etc.

Midway USA makes a cheap two-part belt. I’m not looking for anything super-fancy, but the two-part setup is nice. I can mount all my gear on the outer belt and just velcro it onto the inner belt come match time, without having to undo any buckles. It holds my gear just fine. (That’s 1lb, 14oz of gun for those of you keeping track, plus 77 rounds of .40 and four magazines.)

Cook’s Holsters makes a decent Kydex competition holster starting at $47.95, or $67.95 if they install the TekLok and drop/offset rig for you. I had them do so. The holster is low-cut in the front, and has adjustable retention by means of a pair of screws running through springy rubber washers. The drop and offset are nice, making the draw a good bit easier.

I’ll continue to use my ten-dollar MOLLE-strap canvas Amazon-bought triple pistol mag pouches for magazine carriage. They do the job just fine; the retention straps fold out of the way easily, and on the Midway USA belt, they’re pinned in place by the inner belt.

In Sum

Here’s what I spent.

  • $506: CZ P-09 .40, night sights, 3 magazines
  • $294.60: Cajun Gun Works internals
  • $303.20: CZ Custom magazine well and magazine parts
  • $46.53: Fourth magazine
  • $104.27: Holster and belt

In total, the cost of this race gun project was $1224.60. (Or $1254.60, if you’re buying the magazine pouches too.) Even counting a trigger scale I bought and a case of test ammunition, the project tips the scales at under $1500. Has it reached the magical point of ‘good enough’? Only match experience will tell. Check back toward the end of April for some thoughts with that in mind.
