I carry a G36 as my primary (got 03 of them in fact). My experience with hosters is as follows (FWIW):
Don Hume IWB -- used for three weeks and tossed. Save your money for a better and more durable holster.
DeSantis Summer Comfort IWB -- very nice 'step up' from the Hume. Comfortable, but lost some of its form due to sweat in the TX heat (somewhat of a disappointment).
CrossBreed Super Tuck -- Excellent IWB CC option. The natural horsehide upgrade is well worth the money (I've owned both cowhide and now the horsehide). It is pricier than the DeSantis, but much more comfortable and cooler. The only downside is that it is rather large.
BigPa Texas Tuck (Rockin bull Leatherworks) -- Well, for $50 shipped in TX it's probably my favorite. My elder son (1st LT USArmy) carried his Combat Commander in a TX Tuck, and his younger brother carries a Compact Crusader in a TX Tuck. I've never met Steve FTF, but would buy from him without hesitation. I would put his product on par with the CrossBreed. The only reason I wouldn't rate his work better is that he doesn't offer an upgrade (natural horsehide) on his leather. Nonetheless, the TX Tuck is my everyday carry holster.
Hope this helps...
