I have the polymer, semi-compact .40, and it will be my carry piece when my CHL comes in (hopefully in a couple more weeks). It's a great, and attractive, gun.
Fobus makes a paddle holster for the gun, but you'll have to get it off of Ebay (to be shipped from Israel) as FobusUSA doesn't seem to import them.
I was pleasantly surprised to discover, last week, that Blade-Tech makes two IWB holsters for it. They may make other types of holsters for it, as well. I didn't look.
Trijicon and Meprolight both make night sights for them. I still haven't decided if I'm going to get night sights.
And those are ALL of the accessories I've been able to find. Ah well. lol
