I am looking for a holster for my GP100 for Hunting and general outdoor carry. I would like a holster with a flap. I see Simply Rugged has these two models with a slight difference. The Flap Jack looks to have the flap attached on two snaps, and can be removed. It would still have a hammer strap for retention, but the flap is supposed to allow a draw without having to open it. The concerns I have with the Flap Jack is the flap either coming off, or more importantly, does it get in the way under clothing. I have no intentions of wearing it IWB, but in the winter it will be under a jacket or inside Bibs. Under clothing like this, can the flap still pivot out of the way to draw? On the All american, the flap would serve as the retention, and I am leaning towards this holster. The thing that draws me to the Flap Jack is the ability to remove the flap, which may or may not be any use to me. What are your opinions on each?
