Because a G21 is a fat gun and I am a slim man, 5'10" at 145 lbs. I don't need anything (leather or kydex) making the weapon any thicker.

I must have tried 20 IWB holsters at the local gun shop, and the ones here in Utah are well stock with quality gear, and none concealed it better than the gun shoved inside my pants without a holster.

I understand the benefits of a quality holster, but they just aren't cutting it with this size of this handgun on my frame. I am determined to not sacrifice the caliber, barrel length or mag capacity to fix this, so I am looking at alternative routes.

The clip seemed like a good idea to add to the shoved down my pants method, but was lacking in the trigger coverage. The Zack Holster or MIC Holster (they are the same thing) is a solution to this.

As for comfort, I have carried my Glock all day, in condition 3, without any issues with it shoved down my pants.
