Well you now have the best all around handgun there is. I see you're making a point again though to bring up your use of srp's. You likely will have no issue firing them as long as that gun remains in it's stock form but if you start reducing power on the hammer spring you may well experience light strikes as you posted about in another thread. As to the variation in magazines without a picture it's hard to say what's going on there. I've owned many CZ's and always gotten a pair of identical mags with them.
Only spring I may change out is the trigger return spring along with the floating trigger pin. After I get a few more rounds thru it, I’ll order a set of night sights for it.
The DA trigger pull is shorter on my PCR than on my PO1, which is a plus for me. I tried them side by side.
A very pleasant DA pull and it will only get better. I hope the SA pull stays at 3.75# on the PCR and not get lighter. The PO1’s SA pull is 3# which in my opinion is a shade light for a carry gun.
Also, I noticed not only the hammer is narrow on the PCR, the ears rear of the slide is narrower.
After wife and I went to eat, I moved the rear sight to the center and cleaned and relubed it. Hopefully that will center my groups. I mentioned previously that I was hitting slightly to the left and then noticed the rear sight was left of center. I’ll try it out again tomorrow if the rain holds off.
I hate that my reply is within the quote. Forgive me for not paying attention.
