New P-07 Trigger Pull

[Joe L]

I made you guys a video of what the hammer travel SHOULD look like, this is from my absolutely perfect P-07.  I put a CGW hammer in it, but the stock hammer fit the same as this one.

Joe L - Thanks for doing the video, looks like mine is going back to it's creator (see my video on Page 1). It's had the moving left then back sense I got it new.

Looks like they machined some loose fitting hammers on some of these guns. Mine comes back perfectly straight with the stock hammer and the CGW unit I replaced it with.

Yeah she is all packed up and going back to the mothership in KC. Hopefully it's a quick turn around as I want to use it for a class I'm taking in a few weeks. Thanks for all your guys input. A buddy of mine stopped by today who is basically a gun smith and said that it would most likely wear uneven and would make an inconstant trigger pull so based on that I packed her up and slapped the sticker on that CZ sent me. We shall see.

All that being said, I will caution you that you may not want to expect perfection here. This is a poly service pistol and there are tolerances and clearances and some do seem to vary a bit.

I might use the AK47 reference, however not exact.

But, the design of the Omega system does impose a side loading on the hammer in DA, this is just fact. Now the holes and pins come into play. I an not sure just how consistent they are, but you may just have a pivot pin a little loose as example.

Just saying, I am sure they may well establish some acceptable limits here on this issue. Throw it in the mud and it still works!

I tend to agree but I also think all these companies across the board have increased tolerance standards as to what they accept as useable parts so when we see these issues it's because a part or group of parts that are at the low/loose end of spec end up installed in a gun and we see sloppy function like this. You want to see some real sad sloppy workmanship go handle some new revolvers. I'm sad too see some of the junk S&W and Ruger are shipping these days and Taurus is worse than ever.

Yep.  It's like they took a batch of 50 hammers that were too narrow and had an oversized pin hole and didn't check them and they made it through the firing check and in to the plastic box for sale.  If CZ will fix them in a hurry now, and check them more closely in the future, maybe it only affected a few owners and they can clear this up quickly. 

On the 75 and 97 frames, the opposite is what I've seen.  The frame width is just a little narrow with the hammer cocked, it will almost hold the hammer back due to the rub.  This will make the double action pull high as well.  I've had to polish the sides of the hammers and the frame slot on two guns because it was tight, not because it was loose.  Easy to check.  Remove the hammer spring and move the hammer through its travel range and feel for any tightness or resistance.  Take it apart and fix it if you do.   Usually just a surface blemish on the coating or a rough edge on the frame or hammer.

I believe you're correct on the "oversized pin hole". When I removed the pin that holds the hammer and hammer strut together, it came out without any resistance. I was very surprised because I read in other posts how hard that pin is to remove, but mine just slide in and out, no tool (Roll Pin Punch) required.

I like doing stuff myself but I'm very tempted to send mine off to CGW and have them install the parts and smooth out the rest. After watching a couple videos of amazing trigger actions after sending them off I'm leaning towards the extra expense. I'm in a little better position personally because I picked up my Gen 2 P07 from a dealers personal stash for $350, so after the cgw I'll only be about 7 in it.

The P series hammer strug pins are not very tight.  Mine have all been just snug, not tight like the 75 and 97 guns.  May have something to do with whether the strut pin is captured for the entire stroke of the hammer or not.  Don't believe it is in the earlier guns, so a pin that moves would jam the gun. 

It would have to be loose fit on the hammer pivot pin that the hammer rotates on that would allow the wobble we are seeing, plus the hammer being too narrow.

I recently re-bought a P07 Duty and noticed it had a really rough DA and SA pull. I took the frame and trigger components totally down and did a thorough cleaning. I put some super secret grease on the contact points on everything, and it really helped smooth the pull out. There were also a few metal shavings inside which I'm sure didn't help anything.

It's still no sig or 1911, but it's perfectly useable for a pistol I only paid $390 out the door for.

Just recently had to send my brand new 07 with crooked jacked-up hammer back to CZ and they had it returned to me in 8 working days. Works great now and no complaints. Send them back if your hammer is squirrelly.

deadduck357 - What did they replace to correct the issue (hammer, hammer strut, pin, all)?

The Warranty Repair stated "Replaced hammer, test fired good". No more crooked hammer and it doesn't first move to the left before it starts to come back. All good now.

deadduck357 -  Thanks for the update.......
