Chris makes a good point but I think elaboration is beneficial.
I doubt anyone would enjoy putting 150-250 rounds through the Rohrbaugh on a single trip to the range, as many would do with a .22 semiauto or full-size steel 1911.
However, every time I have fallen into the "carry a lot, shoot a little" trap, it showed the next trip to the range with that gun. Granted, practice wtih some guns transfers over well to others (practice with my full-size .45 1911 transfers well to my Glock 26 despite differences in size and trigger mechanism), this tends to be less true in the case of pocket pistols (practice with my Kel-Tec P-32 does not transfer over well to my NAA G380 despite the similarities in size and trigger mechanism).
In preparing the written materials for a women's self-defense seminar, a friend who owns a martial arts school included the advice "If you carry a weapon, practice with it once a month or get rid of it." I totally agree with the advice whether we are talking about a gun, knife, pepper spray, Kubotan, etc. I think at least 50 rounds a month is a good idea with a pocket pistol.
