A 34 is a full size. 9mm glock subcompact?
This one is about the size of my hand as well, which I imagine will translate to a big kick off the .40.
I'm DYING to shoot it.
For reference, the wife has a 9mm Smith and Wesson SW9VE and I have a Mossberg 500 with custom front and rear grips, folding stock and a full 8rds of slugs loaded up.
