Recently picked up a standard sized Bul Cherokee. It's an older model, sans rail. The pistol is based off of the CZ-75, and while it looks remarkably similar I'm just not certain it has the same dimensions. So my question is (if anyone knows) when looking at holsters, what should I get? No stores around me have any in holsters fitted to a CZ-75, so I can't try it out in store. And I'd rather not drop money on a holster that doesn't fit my firearm.

If anyone can enlighten me on what to look for it would be greatly appreciated. Thank you.
