*Edit* Looked at this again today, and some fo these look a little "off." I think that's because my reference was me holding my TV remote (not shaped like most handgun grips)-then I just kinda "guessed" at what the shapes should be. lol Sorry about that...
Someone asked for a set of close up pictures of hands gripping guns. There are many kinds of guns of course, but handguns seem to be most popular for generic action scenes and stuff, so I focused on that for now.
Regarding the two-hand grips, I kinda just drew what I consider to be a "standard" grip, though I don't think there actually is one. When I shoot handguns I tend to cradle my firing hand with the supporting hand a lot lower than what's shown, but that's probably bad form so I left it out.
More poses, how-to's, etc: [link]
