I put the CZ 75 Compact RUBBER grips on all my metal framed CZs that didn't come from the factory with them. Nice and "grippy."
I put night sights on a couple of them (I think I bought the ones CGW sells). Put a DP Pro on another one.
I carry my CZs cocked and locked (all of them are either safety model CZ75s or Omegas with the safeties installed).
Not sure if any of them have "rattily" magazines but I noticed awhile back that my FNS .40 rattles rounds in the mag. as I walk back and forth to the garage or the shed with it in the holster. Evidently FN can't design a quiet fully loaded magazine either.
Don't notice the weight.
I like the 16 round (full sized mags) with the bottom on them that makes them fit flush on the bottom of the frame. Some of the P01 Omegas come from the factory with those mags. I liked them on mine and ended up ordering a combination of magazines and bottoms (to convert some extra 16 round mags. I already had) so I'd have a few for each Compact/Omega P01. And then, of course, CZ comes out with new 15 round magazines to replace the older 14 round Compact magazines.
I carried my first one enough I wore the finish off the front of the slide, the slide release levers, safeties, etc. I'm thinking of getting it refinished with that hard black finish (nitride??) and maybe carrying it again some.
And, no issues. Neat little pistol.
