Rock Island Armory 4.25in railed 10mm model 51994 OWB holster HELP!

[lopez.texan]

So, I've checked online everywhere for an OWB Serpa level 2 Kydex Holster for my new RIA 2011 Tactical VZ 4.25in railed 10mm. Even chatted online with an Armscor rep, and all they do is point me in the direction of holster makers like BladeTech,  Alien Gear, Safariland and so forth.  Nothing concrete on whether the holsters will fit EXACTLY or not though. Do any of y'all carry this weapon or even know of some direct links to the type of holster I'm looking for? I'm getting frustrated and it shouldn't be this hard to find one that meets my needs. Can y'all please help? Thanks!
