I carried Speer Gold Dots in it and had 5 spares on a Bianchi speed strip. Really though even with practice, it's a lot of fiddling and fairly slow to use the speed strip. Now I carry a Makarov PM. I've got 4 extra rounds of what is essentially .38 special +P power and effectiveness, in a package that is much faster to reload and has proven to be utterly unfailing in THOUSANDS of rounds fired out of it. The lil J got sold. The Mak is on my hip now.
