I just bought my first pistol and it's a Glock 17 Gen 4. I've shot countless pistols but I've never tried concealed carrying one. Any recommendations as to good IWB holsters for the 17? I'm about 6'0 and 170 pounds if that helps any. Also, I've seen a lot of people carry on the hip and right below the belly button at about about 12 o'clock, too. I feel like the 12 o'clock position would be uncomfortable with a full size frame, but I've never carried so I don't know. Thoughts on that, too?
