Dry firing is always good (as long as your technique is correct to begin with).
So you're a graduate student, huh. Good! That means you can, probably, read a book. (You certainly write well enough, though, only in the, 'modern style'.)
I'm going to suggest that you get yourself a set of D.R. Middlebrooks' 'Fist-Fire' DVD's. After more than 50 years of handling pistols (with some success) the, 'Fist-Fire' technique changed my life! I only wish I'd either invented, 'Fist-Fire' myself, or discovered this method a lot sooner in life than I did.
As I continue to age and my body continues to decline I've been (Happily!) able to maintain my pistol shooting ability by a judicious application of Middlebrook's shooting techniques - Techniques which I've, now, studied and practiced in meticulous and intimate detail. For a lot of subtle reasons, 'Fist-Fire' really works, and works very well!
My suggestion is for you to, at least, get the videos; very carefully study Middlebrook's, 'body language'; and apply these techniques to your own personal pistol-handling style. If pistol shooting is something you're really interested in, I think you'll end up wearing these videos out, AND become a much better, 'pistolero' than you, otherwise, might ever have been.
Whatever way you go, good luck to you! (And, you're going to need a larger size pistol.)
ADDED: Beanie-Bean is very correct!
