With so many choices on the market, do you choose a particular brand. Do you simply choose by price or what is available. Also do you run a quantity thru your SD weapon to be sure it feeds and runs reliably. I have had good luck with Remington golden saber sd in both 9mm & 40s&w. I run a box thru my weapon and if its perfect, I trust it and that's what I stick with. These days supply is limited, so at the range I shoot whatever fmj ammo I can get, and hold back at least 2 mags of my carry sd ammo.
