SR9 manual safety assy

Small gripe with the SR9 series Thumb Safety: It's too damn small and slippery. Anybody know if there's a better after market replacement? P/N: VS15000 in the SR manual.

none that I am familiar with. mine stays disengaged anyway, so I don't care. all the aftermarket parts I have used on my SR's have come from Galloway Precision, and that is not something I have seen offered.
