My next gun purchase will be a XD-S but there are none to be had in my area except at the gun shows and all priced at least $200 above the MSRP.
My first hand gun was an XDm 4.5 in .45, My second was an XDs in .45. As Call Maker put it, nothing but the best for those that deserve it.
Hmmm ... I respect the .45's mass and energy, but I have significant accuracy issues with a .45 ... But I assure you that two 0.63" projectiles (from my 9mm Service XD) rattling around inside a skull will - not might or could, but WILL - create sufficient damage to instantly stop an errant bad guy.
9mm is .34 inches unless you were talking length but that is 18mm .68 inches I stand corrected as I looked at the mushroom chart, after hitting solid and expanding out .62/.63 inches it is!
