This thread has been a plethora (have waited all week to use that word) of GOOD information. The single BEST post is advice from Brennan 16-
Ultimately, make sure that whatever you get will feed and fire correctly in your carry gun.
Hydra-Shoks, Gold Dots, Golden Sabers, Black Talons, Zombie Slayers- all of the major makers of defense/ duty ammo make good stuff. But if it does not feed in YOUR gun 100.00000% of the time....you are left holding a poorly shaped club. ABSOLUTE reliability in YOUR gun must be the first consideration. Come to think of it, it's probably the 2nd, 3rd and 4th as well.
It drives me nuts to see someone drop $700-$1000 on a carry gun, $100 for a good holster, and they are too damned cheap to run a couple of boxes of their selected carry ammo thru that gun.
