The GLS xxx-683-yyy (Long) or xxx-450-yyy (Wide Long) models (Safariland fitment guide pdf) would work. For RHT I believe they're found under "CZ Level 2 Holsters".

Eric Grauffel's site and Sebo Weapons have them in stock. I've orderered from both to the states without issue.

Safariland GLS fits my Stock 2's pretty well with the 1911 shim in place. Should fit a limited and stock master as well. GLS holsters dont allow lights if that's a concern.

Is this just a personal observation? 2021 USPSA Open Nationals equipment survey doesn't even have CZ listed. Limited had CZ at 7%. Personally I only see a few other Czechmates around local matches. I predominantly see 2011's. That said, more mag options would be nice.

I shoot Stock 2's in Carry Optics and a Czechmate (TS frame) in Open with brass palm swells on all of them. Both feel about the same in hand (perfect fit for me). I would also consider the Defiant Stock Master (large frame). It's a blend between the Stock 2 and 3.

DAA standalone magnet centerline + magnet on side of first Racer. More consistent mag placement and holds big sticks better. I haven't tried the smaller standalone magnet pouches that have indexing guides.

CR-Speed Compact Race Holster. I found I had to use a zip-tie head as a shim to get the muzzle support to stay at the length I wanted. After that haven't had issues.

To help with sorting for this I've found the technique of using a .40sw ammo tray to do 100 at a time useful. Lets you easily put them all case head down to look inside for stepped brass. Also helps spot .380 and 9mm Mak. So far Czechmate hasn't had issues with range brass.
