What BlackHawk Serpa or Sportster holster will fit SR45....

Hello There, I just recently bought a SR45 (Awesome pistol by the way, Luv it) and I'm wanting to get a Blackhawk Serpa or Sportster holster for it, I have this holster for my Glock 19 and my 1911 and they work great. I'm having trouble finding the right size that fits the SR45? Can anyone help me with this or maybe know what BH holster would fit? I'm almost positive it'll be the same holster as the SR9 and SR40 but I can't find them on BH website either...... Help please!

Allride..... Thanks buddy!

No, it won't. Just tried and the retention device is to short to engage the trigger guard.
