Welcome
Sorry, i dont have what you are looking at. I got one of the previous versions CZ custom was building...
im not sure how you do things or want to do things.
But when it comes to new guns and if you aren't sure you want to spend ANY money one one, i would do my hardest to find one to feel/touch..ect. Im not sure where you live but even if you have to make a weekend of it to feel/touch/try one, i would do that.
do you have any friends that shoot? coworkers/friends/family? Ask them too.
Look for any gun rental/ranges where you live and again, even if you have to make a weekend trip.
Do you have any gun shows where you live or again where you can visit for a weekend?
from the CZ that i got that predates what you want, i wouldnt have any issues dropping the $$ and getting it. Also since i love the CZs that i have i dont have a problem buying another one. Just like the Colts, S&W, Sigs, brownings, EAAs..ect.
as far as not being a young buck anyone...im 61 y/o to be 62. what if found out and im sure you have too and others, is that if you dont use, you lose. Such as muscle tone..ect. If you end up shooting (more) you will find that eventually, over time you will be able to handle the extra weight. IF not, enjoy it while you can and then sell/trade it. Did you look at the weight?? what do you have in your collection that maybe close in weight? You can see how that fits if you have something. not the shootings but the weight since that is your concerned.
good luck
