I would like to know if all Semi-auto DA/SA pistols operation the same. As you insert the magazine does a cartridge auto load into the chamber? I know it may sound stupid, I have aCZ85 and it does not load a cartridge upon inserting the mag., do others as well? Of course I must cock slide to insert cartridge. I see it as a safety feature. The safety only works when in single action mode. Thank, please be kind.
