My new CZ - a couple questions

I bought my first CZ - a SP01 Shadow 91154 I bought at Oak Hills Guns.

Took it shooting yesterday after cleaning and lubing it first and wow is she a SWEET shooter and what a nice trigger out of the box. :D

A couple questions.

Are there grips available that are larger then the factory runner grips?? CZ Custom shows that the rubber grips are the largest they have available at 1.44 inch total grip width. I would not mind trying some larger grips though shooting with rubber grips has not shown to be a problem other than I have a tendency to shoot it a bit to the right and I am a right handed shooter.

Also does any one know what hammer spring is installed in the Shadow I bought? Reason I ask is I am thinking of getting the Kadet .22 LR kit but that ideally at least the 15 LB hammer spring should be in place for the Kadet .22 LR adapter to function reliably.

Finally what are you using to lube your steel frame CZ with? I used Slide Glide medium grease lightly on the fame and slide rails and on the barrel locking lug area and rest of exterior of the barrel. I have been using that on my alloy frame SIGs. Only about 100 rounds through my new SP01 yesterday but no issues as expected. Owners manual did not go into much detail about lubing.

Thanks for any help and info.

Very nice.

I use a grease on my rails and barrel as well. It works well, and there is little wear after over 1500rds at minimum.


The rubber grips are some of the biggest grips that I know of.


I think the factory springs are 22lb, but not sure if the Shadow is the same as other CZs.


As far as weight for a Kadet kit... If I am remembering correctly, they recommend no lower than 17lb for the Kadet to work reliably, and 15lb for centerfire reliability.


Wolff springs has a good selection of hammer springs. They list the OEM weight on their site usually.

The Kadet Kit has it's own recoil spring, integral to the unit that is a different type of spring. When installing the Kadet Kit, you remove entire 9mm or .40 slide assembly, including it's recoil spring, before installing the Kadet Kit. I've never heard of a Kadet Kit recoil spring needing replacement and, as far as I know, you can only get Kadet Kit recoil springs from CZ-USA.

As for GRIPS: If larger grips are needed, a person can probably have some made to your spec from Omega Grips: http://www.czgrips.us/ .. This guy does beautiful work and can do just about anything you might want.
 
Nice group! I want the Target version. Talked to my LGS owner, who said to forget ordering one. Guess I'll wait around and see if one shows up on the web. Meanwhile, I've got the CZ75 Tactical Sport to keep my hand in.

Thanks for the info marine6680. Glad to hear you are on the grease reimine too and it works well for you.

Thanks Walt.

I had read that the hammer spring needs to be a certain minimum weight, 18LBs I believe though 15 may work with occasional failure to ignite. Not sure what the Shadow has installed from factory though. CZ Custom website shows this info on the Shadow model 91154 I have:

Lighter recoil and main springs originating from original CZ 75 Specifications help to create a smoother more consistent action.

From link below on Kadet 22LR kit:

When used in competition-oriented or modified 75 series pistols like the Shadow, a factory-weight 75 mainspring may be required to provide proper primer ignition.

Thanks rt1002003.

Kind of close range though - 10 rounds at 7 yards.

Oak Hills Guns may have what you are looking for. NICE on having the CZ75 Tactical Sport . :cool:

I was referring to the hammer spring Walt... I don't mess with recoil springs.


But I trust you on spring suggestions... as you re the CZ guru.


So whatever hammer spring Walt suggests, I would go with sigarms228.

I misread/misinterpreted the response to which I replied -- and thought it was the recoil springs being addressed. DUH! Sorry all (including marine6680 whose response makes sense to ME, now -- as it probably did to those who read it right all along.)

I've used a bunch of 16 lb. hammer springs (main springs) over the years without problems. I think I might have a small parts drawer FULL of various weight springs, still. I honestly don't remember just WHICH weight is installed in my CZ-85 Combat today -- and that's the only CZ pattern gun I now own that will accept the Kadet Kit; I'm sure it's not a stock spring. I don't remember having problems with the Kadet Kit on any of those guns -- but you have to remember to change the firing pin spring, too -- as the firing pin springs that come from Wolff are supposedly calibrated to match the hammer springs in the same pack. I haven't always changed the firing pin spring, and if others did NOT do it, too, that MIGHT account for some of the light strikes. (A heavier [original] firing pin spring and a lighter hammer spring won't allow as much force to be transferred...)

I don't know that people appreciate the fact that the Kadet Kit is a true blowback design -- with the slide-like upper assembly, the barrel and the sights all working as a single unit. Only a small part of that assembly -- the bolt/slide actually moves. Even if the Kadet Kit isn't tightly fitted to the frame, if you use the sights, you can still have a tack driver -- as the sights and the barrel are fixed and locked together.

Don't quote me on this, but I believe the stock Shadow's come with the 15 lb hammer spring. The Kadet Kit works with the 15 lb spring until it gets dirty and then you might get some light strikes. This is assuming you are using higher quality 22lr ammo (aka NOT anything from Remington).

But, if the OP really wants to spruce up that new Shadow put a 13 or 11.5 lb hammer spring in there. An extended firing pin is often recommended going that low, but on the Shadow's or Pre-B's isn't a must like the B models. I have a beat up surplus Pre-B I put a CGW reduced power trigger return spring and a 11.5 lb hammer spring and it has been flawless. Its easy and quick to swap hammer springs if you wanted to swap between the lighter for 9mm and the stocker for the Kadet Kit.

And, the factory rubber (or plastic) are the fattest grips I know of for a CZ. CZ Custom has a handy Grip chart on their website. They don't list all available grips, but its a good list. Some missing ones are the VZ grips are 1.2" wide, DAA wide aluminum are 1.26", and the Scales grips are 1.330 at the base and 1.110 at the mag release.
 
Thanks Walt and bigmatt.

I think at some point I will pick up a Kadet kit to try out.It sounds like it will work as is with my new Shadow but possibly expecting a small percentage of failures to ignite with .22 LR.

I will also have to order some different hammer springs and firing pin springs to try out.
 
Nice catch as proven by the nice group!

I have the SP-01 also, but I think mine is the Tactical (?). It just reads SP-01 on the side. No other give-aways apart from being all steel, rubber grips and tritium sights.

I had toyed with the idea of replacing it a while back but having taken it out to the range twice in the last two weeks, I have comprehensively fallen back in love with it!! Double alphas at 3, 5 and 9 yds shooting quickly for me. Amazing how controllable the CZ feels after shooting a dozen full-house 300gn .44 Mags!! :D

I should try to do that before every match... Will the RO's let me, I wonder...

Finally what are you using to lube your steel frame CZ with?
Click to expand...

I use Forrest synthetic gun lube: same as on the barrel. No signs of wear that I can see so far.

I also drenched the slide internals, trigger, sear and hammer assemblies in dry lube a while back and that still feels smooth.
 
Where do you want the extra width - at the palm swells, or higher up near your thumbs? I ask because the CZ branded cocobolo grips are the same thickness at the palms, but significantly thicker up top near the thumbs.

I sold mine because I found them uncofortably thick up there, which was a shame because they're really, really, really, ridiculously good-looking.
 
I am thinking I want to try some extra width at palm swell but again no big deal as I am going to work with it as is for now. I have been spoiled by my poly pistols, especially HK P30/VP9, with changeable palm inserts and backs traps. But the marvelous trigger on my SP01 Shadow is spoiling me too, even more so. :cool:

I think I am going to have to get some Nill's grips just because they look so good for dress up days. :D
