Greetings, sir. I currently own both CZ75s and Browning HPs and have owned Beretta 92s in the past although the closest thing I have to it now is the Taurus PT92. My favorite handgun is the current Browning MkIII in 9mm.
As others have noted, it is a single-action design and should be carried "cocked and locked." I've done this for years with no problems, but its short trigger press is not as forgiving of mistakes as the CZ or Beretta with their longer double-action pulls. Note that the CZ allows for either double-action pull on the first shot or cocked and locked as its frame-mounted safety works identically
to the 1911 or Hi Power. The HP is simple to detail strip with the CZ being the next easiest to completely break down for repair or cleaning. There are over 70 parts in the Beretta and I've never had the guts to detail one. However, they appear to work. The Beretta is the largest of the three and would be more difficult to carry concealed. Current HPs and CZs are very accurate and the Beretta 92s do quite well also. I'm told that the newer Beretta "Elite" is very accurate. The HP is the easiest to conceal and the current MkIIIs are very reliable with
many types of ammunition as are the other two. It is also the only one with the dreaded magazine safety. While some may wisely counsel against its removal, all of mine are gone. This, in itself, will improve the trigger-pull significantly. The HP and CZ are all steel while the Beretta has an aluminum alloy frame. If you are not used to single-action firearms, you could get "both" in the CZ-75 for reasons noted above. Still,if you are willing to use caution and respect the weapon as you should, I cannot help but recommend the Browning HP. Best.
