When it comes to shooting you will love your 75. If by "carrying" you mean you'll tote your gun concealed for more than an hour or two you may well be inclined to add another weapon for the sole role of a CCW. I have several 75C guns that to me and my worn out back get real heavy after about three hours. I hate to say it but I had to purchase an additional polymer-framed small compact gun that carries so much better. It has become a tool just like my pocketknife. I like nothing about it better than my 75s OTHER than it's light weight and concealability.
I actually contacted CZ to see if they were going to produce a more compact version of the PO7 and was told no. USA sales of the PO7 have not been what they hoped so far. Funny, they can't build enough steel and aluminum framed compacts to meet demand right now. You'll love your 75 but don't be somewhat disappointed if it does not lend itself to CCW use. It shines in so may other ways. I want a full sized 75 just to keep in my truck at all times.
