Shadow won't hold single action ####.

[skookumchuck]

A friend of mine has a Shadow he bought second hand that won't hold the hammer in single action even when manually cocked. We thought the disconnector looked like it had been messed with and replaced it with a new one but the problem remains.
Any advice?

Could the previous owner have replaced the hammer with the wrong type for that gun?
A hammer which fits CZ 75 DA/SA and SA only pistols, when used with SA only guns, should not use the DA parts.
When a hammer is replaced, the safety, or sear should be fitted by someone competent. There are a variety of different hammer notch widths too. A hammer meant for Shadow 2 won’t work with decocker CZs, Omegas, P07, P09.
Hard to assess online. As much as you’d like to solve the issue yourselves, you should take the gun to a competent smith.
Best of luck solving this.

Yep, the long and short of it is she's dickered bud. Keep it and ammo away from each other until you get it fixed.

Does the hammer fall back to half ####, or does it go all the way down?

If it stops at half ####, the hammer might have damaged hooks that are used for SA. If the hammer goes all the way down, look at your sear. It might be damaged and won’t hold with either set of hammer hooks.

I just edited this as I realized your talking about a Shadow vs Shadow 2. I deleted the Shadow 2 hammer pics. Everything below relates to both.
The discon doesn’t affect single action. Just took some pics of my stock Shadow 2 sear and hammer hooks. Bit hard to see as it’s wet with oil:

You can see the 2 vertical hammer hooks on the horizontal flat sear with the hammer in full ####:



In this picture I’m holding the hammer fully back and you can see the hammer hooks are back from the sear face:



Here’s another ‘cleaner’ pic just for reference. This is my other Shadow 2 with a Cajun sear and Cajun hammer right after the install before any lube. You can see the hammer hooks just barely holding on to the sear in full ####:

I'm not sure about the CZ Shadow line but there are some handguns that have DA only versions of their hammer guns. Is it possible this is one of those?

The new disconnector was different than the one we removed, however for the first two range trips the gun worked as expected.

It stops at half ####.

These pics will be very helpful. Thanks DSG03

If it worked correctly after initial installation (at least for a while) then something has changed / let go internally.

Might be worth stripping it and fitting the original hammer (that is assuming you have the original hammer - not sure that is the case from your original post) to see if that rectifies the problem, in an ideal world you will find the issue in the process.

So you replaced the sear as stated in your opening post and you replaced the hammer as well according to your recent post. Are the trigger screws set correctly using locktite so they don’t move?
What about the trigger bar? Might not be engaging the sear properly causing the hammer to follow.
I’m getting the feeling someone might have messed with the fire components trying to improve the trigger and went too far.
Also, do you have the proper weight hammer spring?
Timing is everything with any semi-auto pistol.

We only replaced the disconnector, not the hammer nor the sear. I mistakenly referred to the discon as hammer in my second post. Someone definitely messed with it previously.

She's dickered...bring it back to spec with OEM parts and call it good.

You're welcome. I'd likewise take the opportunity to thank you for your use of infantile sarcasm, but it isn't appreciated so I'll pass. {ignore list}

Add me too while you're at it, guys is asking for advice, and all you can do is say it's dickered, really insightful.

As to the OP, does it have adjustable trigger screws? If the pre travel screw is set too far in it will engage the the sear before it can be reset.

overtravel screw - take it out and throw away
disco may need to be fitted if it is one of those short reset units from CGW/Eemann/CZUB preB

Done! And if you cared to read, I said the gun need to be put back to spec. Bubba's been in there "tinkering".

The overtravel screw is gone. I've had a chance to compare it closely to my unaltered gun and the hammer hooks have been at least polished and maybe had material removed. They barely engage the sear. It's also what the seller referred to as a competition hammer.
