Tom I'll shoot you an email tomorrow. I found a screw that works for now but would obviously like the right one. A testament to the design that I don't know how long its been missing and I haven't noticed any difference in retention with just the one screw in.
I'm looking at adding some kind of bump to stop the claw wiggle but I'm not sure if I'll find a workable solution for it. Same kind of idea with the clip and adding something to the top to close that gap up. Its probably only a 16th of an inch or two but its just enough to let it slide too low on my belt. Still love the holsters as they are by far my favorite way to carry.
