dont own either caliber and really interested in the federal hydra-shock rather than the normal HP bullets. Keep hearing all the hoopla about mouse guns in 32 and 380 calibers But never hear about hydra shock ammo in small caliber. I have 44mag, 38 specials, 357 mag and 9 mm. Would be nice to add a mouse gun to my collection but golly so many to choose from, and ammo choices, to max out what a little gun can do.
