I've never seen anything that guy can't pick up and ring gongs with at distance. He's a machine...
I found one for my Glock 42, so I may pick it up as well. The Serpa served us all well in Iraq and continues to do so here.
I use Serpas as well. When the weather is cooler I carry my Smithy 042 crossdraw a lot for a BUG and I feel that if I am going to carry it in a manner conducive to a gun grab, I will at least have a Level II holster on for that.

Red clay here too and a few other kinds.....so you know what I am talking about.No, I have not tried the Safariland.
I can see where getting the holster packed full of mud would be a possibility. I ride 4 wheelers on trails a lot and some get pretty soupy, depending on the time of year. We have a lot of the red clay as well.
