Hand cycling will always feel funny. Just go to the range and see how it does.

To get a really good trigger you will need a competition hammer, CGW sear & for short reset a new Disconnector. 11lb hammer spring & extended firing pin. Then you will need to polish the trigger bar and hammer strut. Do not polish your hammer hooks or sear as they are only surface hardened!

Two post are good. No porting no need for the shield.

P-01 Load data
in CZ
Your 4.1gr load of N320 will be about 128PF - 129PF in your P-01.

Most likely you hammer hooks and sear are wearing out. setting the over travel screw with too little over travel does this. Time for a new hammer and sear.

Thanks for the measurements! Is this for a SP01? Your CZC seems pretty close. CZC has theirs published at 2.475". I'm wondering if they changed lengths at some point and made them a little shorter. If you wouldn't mind posting a picture of of the pin where the block reliefs are cut and the end where the hammer strikes that would be great!
Both of my extended firing pins is from 2013

My CGW extended firing pin measured 2.50" and my CZC extended firing pin measured 2.497"

#1 Your Size and decap Die, set it so it's almost touching the plate. 0.003" -0.007" above the plate!
#2 What bowenbuilt posted! Your seating die is taking the bell out before it seats the bullet all the way

In 7 years of hard use never had any of my mags need tuning, #30,000 + rounds on two mags.

I have one with 30,000+ , one with 20,000+, one with 5,000+ and one with 1,000. The one with 30,000+ has shared dude on a CZ tactical sport .40 and an Sp01 Shadow. Milled into the slides. The key when you get a slide milled, make sure that it is milled with the mounting posts! Two post minimum, all four posts are best.

In a week or two, the new spring will look just like the old spring. You will never need more than two big stick on a stage, most of the time you will need one big stick and one 20 rounder. Send two big sticks to Grams Engineering, they will come back and run flawlessly. I think the cost is $8 each. http://gramsengineering.com/services.php

A few years ago VihtaVuori was going to stop making powder and as they were shutting down their plants Nammo/Lapua stepped in and bought the powder business. when they started making powder again under new management the packaging changed. Some say that the powder is just, slightly different.

And John knows what he's doing. That said, it's not for everybody.
Wonder if that clip is why this thread was started. If so, it would be better to just be up front about it.
No never seen Johns video

A stage with a low port, Shooter lays down on is back with feet towards the port. shooting between his feet that are down range of the muzzle? what you thoughts on this, ok or DQ?

The easiest way is to install a mag block and then remove when you are back in your home state. https://www.magazineblocks.com/magento/

Silhouette is a slow burning powder, try a fast burning powder. I use VV N310 in my Wilson Combat AR9. 147gn Blue Bullet, 2.6gn N310 @ 1.150" 132PF
-
Ok #1 get your barrel reamed so that you can use an OAL of 1.155" Auto-Comp will work start at 6.6gn and work up 7.0 will be 170+pf see what your gun likes. Better powders are VV 3N38, VV N350, they produce more gas for the comp.

I get no leading in my Wilson Combat AR9 With 147gn blue bullets, 2.6gn N310 @ 900fps or in my CZ Czechmate 125gn blue bullets, 8.5gn 3N38 @ 1380 fps
