I took my CZ 75 Compact and tried it out in various holsters from my holster bag. Here is what i found that fits so far:
Uncle Mikes pancake holster size 36 (gun rides high but trigger is covered) - this was set up for an LCR so I have to move the thumb break
Uncle Mikes IWB size 15 fits great, feels good against the skin and is more comfortable than leather - but it does not stay open so a little harder to return the gun to the holster (fortunately, the inside top extends above the outside portion so it helps guide the muzzle) - still much better for all day wear than a leather one
Safariland #2 holster for the S&W 39/59 this is an old leather suede lined thumb break holster
Don Hume IWB holster for the XD-C but the barrel sticks out the bottom
Galco Concealable pancake holster for the XD CON 440B this one is a little large, but holds the gun well when worn. Draw is smooth due to the slightly larger width
Bianchi #126 Cross Draw for the Colt Commander this fits great and the retention strap works well too
Unknown maker IWB for the XD service fit is near perfect
Galco Yaqui slide paddle holster for the S&W M&P 9/40 tight fit but works don't like the way the gun butt sticks out but okay for range use
Don Hume No 99 Askins style holster for S&W M&P fits loose until you put it on, then the gun is secure
Of all these, I use the Don Hume Askins style and the old Safariland are the ones I use the most.
