Thanks much for the EXCELLENT link.
I looked around a bit and found the ammo in question on that link. From the data, it seems that 24,000 psi is the maximum pressure for the 9mm Mak cartridge. (I also found this in some other research.) The test results for this load are under 20,000psi. As such, I don't think it is really "+P" at all.
As for the CZ82 in particular, yes, it is a used pistol, but from the looks of it I'll bet my deer rifle has seen more ammo down the tube than this thing has in its lifetime. I may look into replacement springs down the road, but I think I'm going to fire it as-is and see what happens. At worst, I'll make a $210 mistake and ruin it. But honestly I think it will be fine. Trust me, I'm generally of the very paranoid mindset on things like this but I'm willing to roll the dice on this one.
Besides, getting a new spring would prevent me from firing it as soon as the ammo arrives, hopefully on Friday. I already have one new pistol, a Sistema .45, that I've fired a total of seven times because of my desire to replace springs before I use it. I can't put another new toy in that category without risking a brain seizure.
I'll let everyone know what happens when the ammo arrives.
I guess I'll also break out the chronograph too.
Now as for the holster, I kind of like it myself. It is 100% ambidextrous, just like the pistol. As a lefty, that gets big points with me.
