Since I figured out why my Glocks were uncomfortable (very sharp checkering) I think I am going to add to my Glock collection instead of buying the XD. I want to get a .45 and a 9mm. I already have the .40s.
As far as the 9mm goes, would it be better to buy a 19 (compact) and 26 (subcompact) or just buy the 9mm barrel conversion kits for the .40? I may use it as a carry gun, so reliability is of my utmost concern. The advantage of the conversion kits is it is significantly cheaper than a whole new gun and I can get a .45 and a couple of 9mm barrels for the price of two guns. (Think rebate check).
