Kimber UC II Safety

[RaginKajun]

I have just started carying an Ultra Carry in a Crossbreed Supertuck Delux IWB and find that the safety is pretty easily disengaged with regular body movement despite the leather slab between the firearm and the body. Anyone experience this issue or have any suggestions to remediate it?

I have a stainless UC II, and being left handed, I had my local gunsmith install an ambi safety from Brownells like this one, but in stainless. This particular unit rides in a grooved pin on the right side of the frame, instead of riding underneath the right grip panel. The engagement is extremely positive and requires very deliberate pressure on the lever to disengage. A couple of other folks who have tried it out have liked it. My only complaint is that it has left a slight mark on the right side of the grip frame where the it rubs the frame a little as it pivots, and I'm going to have my gunsmith revisit that.

I've attached pictures of mine, with and without the grip panel installed. As you can see from the flaw in the metal on the underside, the part is MIM, or a little poorly cast.
