I've used an Alien Gear Cloak Tuck 3.5 with my previous EDC Beretta PX4 Compact and have been very pleased with its quality and durability.
I can get a free update to a different gun shell by sending in my current PX4 shell and they will send me a shell for my 75 D PCR. I think instead of going with the shell swap, I will just buy a new shell for the CZ so I can switch back to the PX4 whenever I wish to use it.
A new shell only costs $24.88 plus shipping (I hope I can find a free shipping discount code).
I know they offer both IWB and OWB holsters for many different CZ pistols, including one specifically for the 75 Compact. Being new to CZ, I'm not sure if the 75 Compact and 75 D PCR would use the same holster.
