I have more than a dozen holsters that I have tried in various positions over the last several years. During that time, I have gravitated to appendix carry. I think this is primarily due to some shoulder range of motion limitations making behind the hip almost impossible and even 3:00 uncomfortable if the holster has much forward cant. I am fully aware of the pros and cons on appendix carry.
I have both OWB (Mitch Rosen Upper Limit, G&G 3-slot pancake, Blackhawk Serpa, etc.) and IWB (Comptac MTAC, Crossbreed Supertuck, Bianchi 3S, etc.) that I wear in the appendix carry position. Most of these are straight drop or are adjustable to be straight drop, but don’t allow much rearward cant (except for the Serpa). With a straight drop at appendix carry, the muzzle seems to dig into my leg a little when I sit, even with my G27 (more so with my G23 and forget about trying my G22).
Since my Blackhawk Serpa is adjustable, I have tried it with as much rearward cant as possible and it seems to work pretty well. When I sit down, it puts my leg between the slide and butt (please no comments about where the muzzle is pointing while sitting with the gun in the holster). However, the Serpa is not a great concealment holster.
I have practiced the draw from this position and I am happy with it. I have looked at some crossdraw holsters that seem to have enough cant but before I go spend more money on holsters, has anyone tried rearward cant for appendix carry?
