this holster, made by Garrity Gunleather:
Also, while the new clips are longer and more adjustable, I can't think of a situation where I would need to go below the third hole (I've tried). This makes the clips a full inch longer than I would ever need them, and I'm sure I'm not alone. I can cut them down, obviously, but it's still not an advantage for me for them to be longer.
Also, the narrower clip is more prone to tilt on my belt, because it has less surface area. This allows my holster to shfit more than usual, which usually means it ends up further back than I like it. The wider clip has more resistance to the leverage that my holster puts on it, and the result is that the holster shifts less.
I don't doubt that the material is more durable, Kydex is somewhat brittle. It's the choice of holster makers because it's easy to mold, but it's not ideal in every situation.
Retention on the belt has never been a problem for me, the old clips never came undone. Actually, they're almost too tight. It's difficult to move the holster or belt once it's clipped on. When I'm concerned about the clips being visible, I use the Velcro clips.
Are they planning on redesigning all their clips? It seems like the C-clip wouldn't have enough surface are on it to be really effective if you narrowed it that much. And I can't see how they could make the v-clips any smaller and still have enough area for good contact. If they're going to have some clips that are 1" wide and some that are 2/3" wide, I don't see a reason to completely eliminate the old style clips. I'm sure they have a machine that makes the old clips, is there a market for used kydex cutting and bending machines? I don't know.
I don't doubt that the new clip is a "better" design, but I do think there are times when the wider clip is nice. I usually carry with my shirt untucked, so a less visible clip makes no difference to me. Just my opinion.
