For autos, I try for a pocket holster that has a magazine pouch included. My Recluse holster holds my LCP and a reload... and I do have a rarely used double ammo pocket pouch for it. I have the Magguts internal for all of my 6 round magazines... which allows me to carry 15 rounds of .380 in my back pocket.

I have a pocket holster on order for my P938 which is similar... just a cargo pocket holster. I also got a single pocket magazine pouch from the same maker...

For my revolver, I used to carry two speedloaders when it was only in .38. I converted my 642-1 to 9mm, so using moon clips. I usually don't pocket carry it (ankle backup gun), but when I do... I try for three moon clips.
