Speed loaders will work with the hogue bantam grips. I have them on my 342 AirLite Titanium and 642. I've gone from speed loaders to speed strips as ime they're easier to carry.

I posted this elsewhere, but generally speaking, worrying about how your grips look will limit the amount of training / shooting you do, which will hamper your proficiency and you'll probably shoot less, or let your gun sit in the safe. From my experience, nice looking grips, usually there's nice wood involved, are a pita to actually shoot. They vibrate the round explosion directly to your hand. The hogues on the oth are more comfortable and are better at absorbing some of the shock of said explosion. Hottest load I shoot is gold dot +P .38 spl though the 642 or 342. Nowadays I just carry and train with 148 gr wadcutters, either the Winchester X38SMRP or Federal GM38A.

The hogues also slip securely on the j-frame with no screw. If you carry alot in the summer, you'll appreciate the lack of metal screw and subsequent rust.

Compared to shooting semi-auto, I also use a completely different grip when shooting j-frames. Check out the sixth panel down:
