Thanks applesmasher. My CZ52s are strictly range/target guns. I have one in 7.62x25 and one in 9mm Luger. Both have been modified by Novak Sights, who custom installed their LoMount White Dots. They also have new barrels (threaded with a muzzle brake on the 9. Overkill I know.), hardened steel firing pins & rollers, new recoil springs and a new extractor for the 9mm conversion. Some would say "that's a waste on some old mil-surp pistols" and maybe it is but I love shooting my 52s. They could be used for SD/HD in an emergency. I do have some Appalachian Ammo Emancipator 7.62x25 90gn XTP-HPs & Prvi Partizan 7.62x25 85gn JHPs among others which would very effective but I worry about over penetration with any of the 7.62x25 rounds. I have newer safer weapons for SD/HD. As far as safe queens I don't really believe in them. If they never get shot then its time to move on. I don't do collectibles. I used to - bad habit.
Again, Thanks for the welcome and have a Happy New Year!
