How easy is it to detail strip a CZ 75?

I never really touched the Glock's frame internals bar switching mag releases, but the slide was a doddle.

I look at the CZ's frame and slide, with their roll-pins and nooks and crannies and I am afraid to even try.

I'd like, on the one hand, to go around the slide internals and clean them up after almost 1000rds of shooting (not one malfunction!! :D). Beyond that I am very tempted to try the DIY trigger job I found on the "czfirearms" forum.

They make it look doable, but I don't know if I need to be ready with a replacement for each and every roll-pin and frankly it looks busy in there.

I've found a couple of videos, including a short but very effective animation, but any first accounts of what can go wrong would be a great warning.

Not hard but IMHO harder than most. Go over to the CZ forum or poke aroudn youtube and can find a lot of step by step guides. It is a "buys" firearm IMHO but with enough patients you can do it.

Also I do not think after 1000 detail stripping the gun is necessary. YMMV
 
I managed to do it despite being a completely new to home gunsmithing, but I won't lie: it's not easy. Especially if you have a decocker model like I do. The single most difficult thing is the decocker sear assembly, and the FPB lifter spring in particular. Once you get used to it, it's not especially difficult to break down and reassemble, but it took me five very frustrated hours to get it right the first time I tried it.

Since then, I can do it in a matter of minutes - once you understand the mechanics of it, it makes sense. It's still difficult on account of the tiny springs (particularly the l-spring I'd previously mentioned - do yourself a favor and buy a few spares if you're going to work on it - but it's not terrible once you figure it out.

The simplest upgrade is just to change out the FP and mainspring to reduce the DA trigger weight. I can do that in 10 minutes, and it doesn't require mucking about the sear cage assembly. I do plan on doing the full upgrade, though, once I have the time and money.

The gunsmithing section on the CZ forums is fantastic.
 
Field stripping is all that is required to keep a gun running

Spray solvents and an air hose will save you a lot of frustration if you feel it needs more cleaning

Another alternative is a long soak in a container of diesel fuel, with an air pump providing some circulation
 
But its hard to tweak the trigger without taking it apart...

If you are good at taking apart and reassembling things with small parts... Say an old carburetor from a car... Then you will probably be able to detail strip a cz without problems.

The risk is always on you though. And with your location and difficulty getting parts and gunsmith work, you need to be cautious not to loose parts.
 
The only thing I found difficult was getting the rear frame pin out, the one at the beavertail, it was really in there. Also I put the weird trigger doing in wrong the first time, and the little detent on the sping next to the sear. On second thought, I guess it was a little hard. You tube helped a lot though
 
Thanks for the pointers and analogies. I think this is well within my skills in terms of difficulty. It is just the medium that is new.

Parts, on the plus side, are available. CZ and Glock are the two brands that seem well catered for in terms of OEM parts.
 
Simply polishing all the parts will help a lot on smoothing things out and will lighten the pull a little.

To lower the pull weight more... Get a 18 or 19 lb hammer spring. 18lb is concidered the lowest you can go and still get reliable ignition of the primer without changing other parts as well.

I am running a 19lb myself, mostly because the 18 was out of stock... Between the spring and the tweaks to the trigger I did, my trigger is around 10lb double action, and 4.5-5lb single.
 
I'd like to smooth things out first and go from there. If the trigger pull is suitable then great. Beyond that I will have to see. I may be able to get hold of a new spring, but I can't be sure that they will provide different weights. So for that reason it is not my first route.

I can't face doing the foreign lingo investigation until I know that I need it!!
 
CGW's decocker slave pin is a godsend. Unfortunately, I plan to buff the internals which requires disassembling the decocker, so it's a moot point. In the future, though, I expect it to be very helpful.
 
I've done my 97b a few times. It's sketchy the first couple tear downs but if you pay attention to the various videos on YouTube, not that hard.

As pointed out though, just use some PowderBlast or similar firearm cleaner to get the internal junk out. Take any plastic parts off first as the stock grips turned white on my 75bd. Now I know better.
