UPDATE:



I had purchased a holster from Swap Rig Holsters a few weeks ago.  It's made for cargo pockets, but I didn't like carrying it there, as I prefer regular front pocket carry, for which the SwapRig was just too long at the base.
I pulled it out of my box-o-stuff, and sure enough it covered the safety selector, and is made of stiff leather, so it should protect against pesky mag disconnect problems as well.
I ended up cutting a couple inches off the base and repositioning three of the tensioning screws.
Works like a charm.  Yeah, I might get some muzzle wear at the bottom of my pocket, but we'll see.
Here are the before/after pics:


 





 

Nice use of existing resources.



The 9 isn't too much for your pockets? I was concerned the size would make drawing a bit more difficult.
