If you're reloading for competition -as in bullseye, IDPA, IPSC and variants thereof- there is no advantage or need of a 'hot load', provided you make minimum Power Factor. A hot load means the gun recoils more, and takes more time recovering to where you can reacquire the sight picture-this slows down your run. If your application is SD, ammo for that is 'hotter' but not 'crazy hot'.
I chronoed some Police 9mm ammo in my Shadow and iirc, it came in at a power factor in the 170s. I don't remember the velocity. There definitely was a stronger recoil impulse.

"Just for curiosity can you tell me if the linkage of the barrel being tight in battery is the case of the Slide Stop Shaft breaking or something else?
Since I recently got the CZ I have never seen one.
So I am just guessing from what my buddy told me and when I remove the slide stop and reinsert it in to the gun having the thumb release pointing down (parallel with the trigger)
It is very tight and I can feel the barrel linkage pushing down on to the Slide Stop Shaft
If that is the design of the gun I can argue but it seems to me to be too tight not snug fitting."
Now I'm no 'specialist' - just new to handguns but not firearms. But I do quickly pick up on things and have been well mentored by others. So please don't take my advice as gospel.
When I insert the slide stop shaft through the frame bosses and the barrel lug, the outside part of the stop is parallel to the frame/slide axis, rather than turned down toward the trigger. The shaft pushes in without a struggle; you'll feel it click into place when it's fully seated.
Notice that the end of the shaft has a bevel and a groove cut into it. Now look at the frame (or at the parts diagram) and you'll see there is a wire spring on the right hand side where the frame has a thick boss. This spring is pushed up a tiny bit by the shaft bevel, then it snaps into the shaft's little keeper groove.
It sounds like you are not inserting your stop properly, you are forcing the non-bevelled end of the shaft against the keeper spring. Try it with the slide stop parallel to the frame/slide axis.
You may want to put a straightedge against the slide stop shaft
to see if it is bent. If that is the case, you've found another reason for this tight fitting problem.
Good luck.
