Purchased the Galco Miami Classic II (MCII224) which fits the Glock 19, 23 etc.
Fit's like a glove, retention and comfort-ability is excellent. Galco can be tough to break in, place the P-01 in a couple of plastic bags, place it in holster and tighten retention screw. After a few days loosen retention screw and the P-01 will be easy to draw. To make it easier and or faster to break in wrap gun in wax paper and draw and reholster a couple of times.
I have Moprolight NS's on my P-01, you may want to remove a small amount of leather around the sights if this bothers you, otherwise it will break in on it's own and has no negative effect or draw or reholstering.
Not much needs to be done for the magazine carrier since the Glock mags are thicker than the CZ's. Just place mags in the carrier and tighten retention screw, works great!
