CZ open 9mm

[GrumpyOne]

Well, these aren't CZ's, but they are clones. They are Springfield Factory Comps in 40 S&W. I've had them for several years now... Far as I can tell, they were made back in '92, '93.

Those are sweet looking guns. I'd like to try that straight trigger once but I don't know anyone in the are who owns one.

The website proudly explains that the Open blaster is part of "the CZ 75 SP- 01 family, from which comes the handgun of the double World Champion in shooting according to the rules of IPSC Production Division, Mr. Adam Tyc." Ah-ha!

The one with the red dot has 1.5 lb trigger, breaks like glass, the other, believe it or not, is bone stock. It breaks around 3.5 lbs. I still shoot them in pin matches.

Someone needs to find George Heuning, and buy him an expensive steak dinner and a lot of booze to try and coerce him back to the gun world.

Where did you get the thumb safeties?

Safeties from Angus Hobdell USA:

The safety on the picture is the original one. The extended safety bought from Angus is placed on the left hand side of the gun.

Oh, FYI: Bevin Grams is making spring/follower kits for the 19rd CZ mags now FKC-11 is the part number you are wanting.

Very interested in seeing some pics of how you've set up the jpoint, any chance you could post some pics of your SP-01

Here they are: CZ SP01 Open 9mm Major

I haven't seen Venry for a while, and I not sure he is working on these conversions. The key element is the compensator, especially if you are using the original SP01 barrel which does not have an extra length over the end of the slide. I think it could be a little easier using a longer barrel. Initially I bought a 6" barrel from CZ think it would be a must to install the compensator, but Venry figured out how to do it with the original barrel.

Compensator by Venry; Single action conversion by my shooting buddy Shay1911, sight mount manufactured by another shooting buddy and installation by Derek (Millennium Custom), big safety and magwell installed by me - it was a long span, multiple hands project - we all are from the same club SFPC

Oh man that is too cool!

Do you have to unscrew the comp to get the barrel out for cleaning?

I have those. I can get 24 rounds with the CZ 19 rounds mag and the Pearce Grip basepad, but they are unreliable. I have tried almost everything I could think of to make it work. They are not reliable with the Tanfoglio mag either, but the 9mm Grams kit works flawless with the big stick made of a CZ-26 mag.

By the way, they are the standard Grams follower made for STI/SVI, roughly shorted to fit a standard 9mm mag.

No I do not. I can clean it with the barrel / compensator in the slide. The compensator is attached to the barrel by threads and thread lock glue (Loctite).

Thats good to know, what is the bullet doing? nose diving? what would you say

is reliable 22rds? how about 23?

[Big Dog Howie]

I have Bevens new FKC-11 and used them this weekend in my CZ 19rnd mags with Angus's + 2 base pads giving me 22 and not one hic up,ran perfect.I think if I mill the indentations at the bottom of the 26 rnd long stick I could probably get 28 or even 29.Will have to see.What do you think Ed.

Not reliable with any number or rounds. I did almost everything I knew trying to fix it - longer loads / shorter loads / cycle springs / cycle mags / file the mag release to make clearance close to the feed ramp. It nose dive before the first 5 shots are fired. In the video I posted I started with the big stick and reload a CZ mag with Grams follower - FTF at the end of the stage.

On the other hand, it works flawless with the big stick. It was built by Venry and I think he tuned it (I never asked). The CZ followers have legs that keep the bullet angle up all the time. When Grams follower is used, the bullets do not keep the same angle - it is lower. On the big stick, the bullet angle is always up, like the CZ follower angle - that is my only clue to go to the root cause of the problem, and why it works fine with the big stick.

I get 22 rounds reloadable and reliable on the CZ mags with the original follower and the Pearce Grip basepad - they are not great, but at the time I bought it they were the only basepads available for CZ SP01 (Angus only had it for the TS). Now, by filling the bottom of the follower longer leg, allowing it get deeper into the mag, I can get 23 rounds instead of 22.

For me, it works on the practice range, it works on some stages, it sometimes works for 3 stages in a row (our weekly matches), but it is not reliable for matches. I never tried the Angus +2 basepad, but my guess is that you should get 22 with the original follower and 24 with the Grams follower.

I do not have any experience with the CZ 26 rounds mag, but my guess is that if the indentations are in the way, removing it will increase capacity. I have seen similar solutions with Beretta mags, and it works. I do have a Tanfoglio 26 rounds mag that has no indentations and with or without Grams follower it is still 26 rounds – loser with Grams follower, but still 26 rounds.

Yep mill it off, key is reliability! build your equiptment

then know what to maintain it, then reload and shoot!!,reload and shoot!

Just got my Grams kit in the mail, but probably won't be able to try it til this weekend. Have both factory and Mec-Gar AFC mags, as well as some different basepads so I plan on doing a little tinkering.

Upon speaking to Bevin on the phone (who I can't say enough good things about, guy is as nice as they come, and really bright), it seems the CZ mags suffer from having fairly loose "tolerances" (for lack of a better term). Specifically, those ridges where the mag goes from a double stack to a single is often mis-shaped, which likely is the root of the nose-diving problem.

Wonder if I beat/pry on those ridges enough with a hammer/screwdriver I can tune my mags into shape?

Hello FFL1911,

From your description of the Grams Follower Kit you are trying to use in your CZ75 mags, you are not using the FKC-11. This new follower kit is designed closer to my Tanfoglio follower not the Grams STI/SV follower. At current production, the follower is marked "TC" in the bottom of the follower. You may be having problems because of this. But, I would also suspect that your 19 round mag tubes are not shaped right, compared to your big stick, since the big stick seems to be working fine (J-Hon touched on this issue in a previous post). I would also assume that you changed to a 13 coil spring for the big stick. I welcome any questions on this, just give me a call.

Beven..so glad to hear you are doing some CZ stuff

is the follower specific to the 19rnd SP01 mag? or would it work in other CZ/MecGar mags?

thanks again.

Part #FKC-11 and FKC-13 will fit mags related to both the "small frame" CZ75/SP01 and "large frame" Tactical Sport" type guns. The 11coil kit is designed for mags that are up to 145mm in length, and the 13 coil kit is for longer mags up to the 171.25mm mark ("length of mag" means tube and base pad combined). These kits will not work in mags that have "dents" or "protrusion" to the inside of the tube, that narrow the inside of the tube smaller then a double stack of ammo. With the large variety of mags available for the CZ line of guns, both factory and aftermarket, it is impossible for me to say specifically which tubes will work properly or if there is a specific issue with one type. I have designed these kits to work with the factory mag tubes I have on hand. As time goes on, I collect more mag tubes, and try to keep up with the changes that materialize. I find that even factory tubes change from manufacturing run to run, and can have a huge influence on the reliability. If someone is using a tube that seem to have an issue, I welcome phone calls to help figure them out.

I am not sure how you could get 24 with the Grams kit,I could get 23 if I push it,but why slam it up against the ejector on a reload and it might not be reliable.22 rnds in mine feed everytime and thats what I am looking for.Whats worse having to reload in a stage because you have 22 or having a hicup with your mag in the middle of the stage because you got 24.Ed has taught me a lot shooting with him,and the biggest thing I have learned is make sure your equipment is reliable and works everytime you use it don't get hung up on more when less will do the job perfectly.

Oh and thanks again Beven
