For all of the reasons the previous posters said, I have a G29 SF. Packing the max number of 10 mm rounds in a firearm as small as the short frame is, to me, the ultimate SD weapon of choice. My preference is shooting wadcutters through a 4" Lone Wolf ported barrel. The only other change I made was an exchanging the original slide lock for extended slide lock for easier dis-assembly.
This is my first Glock so I'm still getting used to it, but I would feel comfortable carrying it concealed. It is also my weapon of choice as a backup for hunting.
