From time to time I'll carry a S&W 310 with 40 S&W/moon clips in a Milt Sparks PMK. Double speedloader pouch made for 357's will allow 2 stacked moon clips of 40's.....that's 6 in the gun, an 24 on the belt. Fairly fast to reload.

Could do the same with 45's in a 6/325. With 357/38's a 6/327 will hold 8 rounds but I don't think you can stack 2 in the pouch due to the longer length....maybe you could with 38's.

Lots of good options. Regardless of what I carried on the belt, I'd probably have jframe/LCR in my front left pocket as well.
