A few thoughts. Since you said you like the regular AIWB, there is always the
George model. It has a reduced wedge, so not quite as much girth at the belt. I have one, and it definitely makes a difference to reduce the excess bulk. It never quite goes away, IMO, when you have stuff stacked directly over the trigger guard.
Personally, I've had the best success with the
WC2.5, specifically with PTD loops and wide hole spacing. With the position of the snaps on the loops, it naturally offsets the belt just a bit from the apex of the trigger guard and grip, giving just a bit more clearance to establish grip. This also has the effect of ensuring the claw definitely shouldn't be sticking up above the belt line. With the DCC clips, I know there is a degree of adjustment. I'm just not sure if you can adjust it to a similar level of clearance.
Also, one thing I've found is, I feel like the PTD loops being mounted at the top of the holster body on the WC2.5 adds to the stability. If you think about it, with something like the DCC clips mounted well below the belt line, there is maybe a bit of added potential for movement, versus being mounted directly at the belt line. I might be wrong but, intuitively, it just feels right to me. I've tried the DCC's on the WC2.0 and 2.5 but just couldn't warm up to them.
Those claws (
ModWing) lend themselves well to being modified, and they're cheap to replace. There's enough room you could chop maybe the top 1/3 off of one, still get enough surface on the belt, while ensuring plenty of clearance from your grip.
