A friend of mine recently bought one of the CZ-75 Compact PCR models. This is a decocker model with an aluminum frame. It is a few ounces lighter than the standard all-steel compact. I like it a lot (I recommended it to him, and I'll probably get one myself one of these days).
We tried it with the standard size magazines and they worked fine in it (although they do stick out maybe 1/2"). I bought a couple of the compact high-cap magazines from CDNN (per Tecolote's recommendation) before the ban here in California, along with several of the cheaper full-sized magazines. I plan to carry the pistol with a compact magazine in place, and with a couple of full-sized magazines for extra ammo. The full-sized magazine doesn't matter when you are shooting (might even give a little better grip), the only disadvantage is that it makes the pistol larger to carry.
