From what I have read it appears that you are set on IWB, might I ask why? Good choice on the gun.
I have an issue with IWB for several reasons and it seems people always argue with me. I've had a lot of training over the years and can quite easily stop draws on an IWB quite effectively. I am not saying I am some super bad ass, but I tell you that to tell you this: 90% of the time someone who wants you to be a victim will have the "drop" on you before you even know what's happening--alertness can only go so far. I have rarely been involved in an incident which was over 8 feet away. EVERY second counts and I don't like ripping away at clothing that someone can use to drag me around with. I can draw quickly no matter where I have a weapon mounted, but I always find myself moving my position a lot more to draw IWB than I do ANY other method. Yes, it's deep concealment--what does it matter if you cannot get the gun? I have always said if they know you have a gun they will generally avoid you, or come in a group. Yes, you can also argue that the person attacking you does not suspect the weapon, or does not suspect any resistance and I will agree with that. I can also tell you 5 out 8 times if you are on the ground or injured before you draw, you won't be getting that gun out to defend yourself. A lot of people that CCW **NEVER** think of the ground fight that can ensue if something is mis-calculated. I always think of worst-case scenario, and for me IWB always looked most grim for what I felt was the best way to arm myself. //end that rant.
Aside from that, I just never quite found a IWB holster that I ever did like much but my body type is a bit different than most. I can do SOB IWB, but only do that mirrored on the occasion that I do it.
That's just me though... and I never claimed to know a lot.
I will add to this later, I've been procrastinating a project I must finish.
