Expensive. More than three times a Mika's.
You can also choose a holster for the P88 compact. Warn you, it will not be a snug fit. The P88 compact is slightly longer and somewhat wider. But it will do with a thumbstrap. Fwiw, I carry mine in a Mika's pocket holster IWB. My body type makes it stay put.
If it were a Paul Evers, I'd have the speed sheath.
