Best upgrades for CZ75 SP01 Shadow ???

Ive put about 2000 rounds through my shadow and my upgrades so far are the recoil spring, main spring and firing pin springs. They are cheap and easy upgrades that improve the gun. Lighter trigger pull on both da and SA. I also changed the hammer to a competition version. It is supposed to further ease da pull. Not sure I noticed it though. Jury is out on whether the steel guide rod makes a difference or not. I did change from rubber to alu grips cause I have small hands and found I had an easier reach to the trigger. It's still a touch long on the da pull but works with a little reach. DLask arms, select shooting supply are the ones I shop at for cz parts.
 
I also prefer the stock grips over the Aluminum...but the aluminum ones look AWESOME! I'll be swapping out the main spring, recoil spring and SS guide rod with buffer as soon as the parts arrive. The gun shoots awesome stock, but it can get even better. I'll have the opportunity to directly compare stock vs lightly modded SP-01 shadows.
 
No mention of a pre-B disconnector? This along with the competition hammer has really improved my trigger reset.

11lb recoil spring on a stainless guide rod from Dlask, with a shockbuff, also from Dlask. 11.5 mainspring unless using really hard primers. lighter firing pin spring, aluminum grips, skateboard tape on front and back straps, thinner front sight with 1mm rod, and most importantly FLUSH SAFETIES.

This guy pretty much nailed it.
I was using hard primers and went 13# mainspring
Don't know for you, but 147gr ammo got my groouping high, and to heighten front sight to 6.0mm. (Factory 5.5mm)
 
thanks to the poster who said Pre B disco, missed that in my haste, and competition hammer
 
I put a single action trigger in mine, just for a bit more LoP.

You guys running lighter springs - do you shoot lower power target loads? I'm wondering about the extra battering the gun would take with standard loads.

Or is this the reason for the guide rod + shock buffs upgrade?

I personally don't care about the stock guide rod one way or the other, so have no plans to replace it.

So what upgrades are suggested to the SP-01 Shadow to remain legal in the IPSC Production Division?

I would say: 13 lb main spring, 11 lb recoil spring, pre-B disconnector, competition hammer, steel guide rod, (maybe small safety) and grips of your choice...and some "advanced wear" on all contact surfaces.

Parts need to be real CZ parts and DA pull has to be above the minimum (4.5 lbs?)
 
Thanks guys for all the replies !
Very interesting information.
Continue to share your mods with us.

Pictures are also welcome :redface:

Flush safeties, really ?

Is there a version of the CZ that has most of these mods done at the factory such as the SP-01 Shadowline?

An CZ expert will have to chime in...
 
Other than the 13 lb mainspring there's precious little to modify. The recoil spring isn't something you do "just because I want to mod it". The recoil spring power is set by the ammo you shoot. Otherwise you risk the gun battering itself to failure or suffering from poor ejection behavior.

A trigger job is a lot more in a Shadow than just the sear to hammer hooks. In fact those are just about the last parts which need attention. Most of the improvements come from fitting and polishing and working the trigger area, the trigger bow and disconnector parts and the foot that runs on the ramp in the slide which controls the DA release point. The trigger is going to improve more from detailing those points than from the sear and hammer. The sear and hammer hooks start off a touch gritty but quickly burnish themselves from use. By the time you shoot a couple of hundred rounds or dry fire a few hundred times the surfaces are as good as they can be on the hooks.

Now if you just dive in and attack these parts with a Dremel expect to ruin your gun. The points along the path of parts between the trigger and the actual sear need to be dealt with using the proper tools and techniques. They can't just be polished with a rotary tool until the shine and expect to work any more. You'll alter the shapes and critical angles enough to ruin them if you try. The tools and methods are detailed in the various sites that discuss the trigger jobs that can be found from a google search using "cz trigger job" for the search keywords.

The hammer is already a competition hammer so there's no advantage there. And for my shooting the competitions I like don't allow me to replace the guide rod with a metal one.

I've got fairly big hands so I found that the stock grips fit me best. And on top of that the rubbery feel really helps with my gripping the gun during hot summer day matches when I'm sweating up a storm. So no aluminium or shiny varnished wood grips for me. Oil finished wood might work well but with the sweat and grit they wouldn't look good for very long.
 
The Shadowmate has all the whiz bang stuff done to it, except the lighter hammer spring. They say they ship them with a selection of them, but I have yet to test one and find even a 13lb in the pack.
