If I spread my hand on a flat surface it's 8" from the tip of my thumb to the tip of my little finger. My "standard" 5" 1911s feel perfect. My Glock 19 is great but my little finger doesn't get a good brip on the base of the magazine. OTOH, my Springfield XD-9 fits perfect, too. K-frame Smiths feel great, bu there are so many different stock options on those I ain't even gonna go there. So what's the scoop, guys? Is there a ref somewhere that I can peruse to get a grip on my grip?
