It seems to me that this is an often overlooked category of research for the newer shooter or first time handgun purchaser. After being at the counter when a new shooter is asking questions of the gun shop employee this never comes up until I mention it and then everyone involved on the conversation suddenly looks at the size of their hands and says "That thought never even crossed my mind".
So I decided to take it upon myself to start a thread, since I could not find one, that would address this issue with a wide range of hand sizes and what you prefer to shoot according to that or what modifications you have made to accommodate your meat hooks.
Since I am starting the thread I will give some parameters to follow. We could break this down to surgical accuracy (finger length vs. palm size)but, I will stick for simplicity's sake to overall hand size measured from the crease below the palm to the tip of the middle finger.
I realize opinions are opinions but, I am willing to bet that hand size has a lot to do with what we settle on being our best and most accurately shot platforms.
I have a 7 7/8" measurement as measured from the parameter above and find that most single stacks move in my hand while firing simply because the grip circumference is too small.
For me this is critical as for years I owned and learned my basic shooting skills using a Sig Sauer P220. This is a fine weapon but, i was not happy with my accuracy initially and it took years of practice and manipulation (and a wrap around Hogue grip) to realize that the gun frame was just too small for my hand.
Shooting anyone else's double stack handgun in almost any manufacturer's platform would instantly change my shot placement and follow up time between shots. this was truly accented when my buddy got a Springfield XDm in .40 and I shot tighter groups the first time I picked it up. He has smaller hands and loved shooting my Sig 220. I have since sold my Sig and have an XDm in every caliber available.
I also have found that I am accurate with almost all double stack platforms and really have to concentrate on grip when I move to single stacks. I look forward to seeing how much this affects the platform you like or if I'm just making a personal observation.
LET THE GAMES BEGIN!
