Tight Safety on SP-01
« on: May 22, 2020, 10:23:50 PM »
Had my SP-01 for several months and I don’t think I’ve ever messed with the safety. Tried it out tonight and it wouldn’t budge. My Shadow 2’s safety is very smooth and easy to engage.

So, are some CZ safeties tight and need to wear in with some lube?

It varies from pistol to pistol. It should wear in over time. If it is not wearing in fast enough for you some minor fitting may remedy the situation.

Will work for CZ pics! (including but not limited to all CZ clones)

Must be just a tight finish. Finally got it to engage. Goes back to fire easily but is still a bit tight to push it up.

Is the hammer fully cocked back? In factory configuration the safety should only engage with the hammer fully cocked.

One of mine (not sure now if it was the P09 .40 or a different CZ) was really tight.  I put some oil in the right spots and started working the safety on/off (unloaded of course) with my right thumb, then my left thumb, and finally with a finger.  Back and forth for a good while when I was watching TV.  Finally worked it looser and no issues since.

As Tok36 said, some are just tighter than others.  They will wear in.
I stopped carrying the SIG 556R.  SIG changed models and couple/three times and stopped supporting it with parts.  So, I stopped supporting SIG.  Back to the tried/true AR15 Carbine.

It is not stock. Has the Villain trigger package from CJ Maven. DA and SA much improved after the work.

Update: as mentioned earlier, I did get it to engage. And I worked it over and over until it smoothed out. Ran it cocked and locked on several stages of an IDPA match yesterday. When I clean the pistol, I’ll add some oil and work it in some more.

With a new hammer the position of the sear, in relation to the safety usually changes.  The sear will not rotate as far (clockwise if looking at it from the left side of the frame) as it does with the factory hammers with deeper full cock notches.  That can result in the can on the left side safety shaft not freely (or at all) rotating (clockwise again) as you put it on safe.  That cam has to move under the forward arm of the sear to lock the sear so that it can't move and release the hammer.

First time I changed a hammer getting that safety cam modified "just right" was  bear as you have to remove it from the frame, remove some small amount of metal, reinstall and try and then repeat if it doesn't work.

After that, I just ordered a CGW adjustable sear every time I replaced a hammer on the CZ75 series pistols.

Did you put the parts in or have it done at a shop?  Either way, taking the time to get that cam modified correctly (or installing a CGW adjustable sear) would have saved you some wonder/worry.

Green arrow points to the forward arm of the sear that the cam on the safety shaft rotates under to keep it from moving (firing).  Red arrow points to the cam on the safety shaft.  Some people remove metal from the cam, others from the sear.  Or buy the CGW adjustable sear.



There's also a spring/detent in the frame on the left side that locks the safety into the frame but usually, the complaint on those is that they are too loose/easy and allow movement of the safety without enough effort to satisfy people.  That usually doesn't get changed with installing "upgraded" parts or doing smoothing/trigger work so it probably has nothing to do with your issue.
I stopped carrying the SIG 556R.  SIG changed models and couple/three times and stopped supporting it with parts.  So, I stopped supporting SIG.  Back to the tried/true AR15 Carbine.
