P10F OR upgrades for competition

Recommended Posts

Posted (edited)

1) I have a US made P10F OR, and it's slide to frame lock up is rather loose (0.04" play L/R with vertical play as well) and rattles like an old 1911 when shaken.  I've put about 300 rnds through it and can't get it to hold a tight group. For example, using the same ammo, I can shoot inside its group by half with my P-09, P-10C, and Shadow 2. 

2) Also, I installed a HB industries Theta Trigger and striker spring and 15lb recoil spring.  Every 2-3 rnds the trigger doesn't reset, although the slide has fully cycled and loaded the next round. I could cause this malfunction during dry-fire by functioning the trigger, pulling up on the slide, and cycling it while pulling up.  

 I've taken the pistol back to stock but I can't replicate the malfunction.  I like how this pistol feels and my P10C functions flawlessly with the same mods above.  It's very frustrating and eroding my confidence with this specific pistol.

 

Edit: PS: I should also add that I originally installed the aluminum CGW trigger before the HBI Theta, it did the same malfunction. 

 

Thoughts?

I could only think something wasn't quite installed right with the trigger...but hard to say without looking at it..

 

Hope someone here with more knowledge can help.

Same thing happened to me. Put an HBI trigger in my P-10C and it works great.  Put one in my P-10F and it won't reset.  Put the OEM trigger back in and works like it should.

did you get the correct HBI kit? The older variations won’t work with the new OR models. HBI has a picture/warning about it in the description..or at least at one point.

I bought the trigger direct from them in Jan 20.  I looked at their website and didn't see anything about a P-10F OR disclaimer.  I'll probably send it in to CZ once they open post plague shutdown.

Then you should be good to go...maybe something else going on

Trying to decide between a p-10f and an m&p9 5” 2.0. I’ve got a 4.25” 1.0 with an apex kit, 6 mags, and a holster so I’d have some crossover. Going to be for carry optics with an SRO on it. Different things I like about each and can’t decide. Anyone else go through this and have opinions?

Anyone else seeing problems with bulged brass from their P-10F? These loads were 145pf- too hot? The chamber on mine is pretty generous, and even this bulged case drops back in. After resizing, it causes this crease/fold on the brass and I toss any like it to be on the safe side. It's a pain when 50% of the cases fired from the CZ have this.

Hey Blake what was your OAL on the 160s? I’m thinking of trying some of those. What brand were they?

Is that bulging or is it necking underneath due to excessive headspace? Does it drop into other 9mm chambers?

 

 

does anyone know of any indications for CZ to make a long(er) slide P-10? If the C and F were the G19/17, then a G34 equivalent?

You'll have to explain the necking- I'm not familiar with the term. 

 

The cases drop into my CZ chamber, but do not with any other pistols.

I was just thinking that if the chamber in the barrel was long and the extractor had some slop in it for the case to be seated off the breechface of the slide, it would stretch back (after expanding to grip the chamber) and that would locally "neck" or reduce the outer diameter of the case. But from the sounds of it not seating in other 9mm chambers it's expanding/bulging instead.

That's what I was afraid of. Maybe once CZ-USA is open again I'll call them and see if I can get a warranty claim on the barrel. I can't imagine it's supposed to allow the brass to expand that much.

Would anyone with the suppressor ready version be able to measure the distance between the front of the rear sight and the breechface? I was hoping to get one and mill for an SRO yet maintain the rear sight if there’s enough room
