I have a couple SA only and SA/DA's, but I recently bought a .45 which will serve as another HD option (in addition to my Glocks and AR's. My choice was a PPQ M2 .45
Great trigger (best striker trigger I've shot), good mag capacity (12 rounds), decent price ($600), metal sights (not night sights though). And a very nice, ergo friendly grip for a guy who (sadly) doesn't have "gorilla paws".
Used to have a G21 and it was just too big and blocky...I do own and shoot the 9MM and .40 Glocks but the G20/21 size is just too big, as is the FNX. Love the HK .45 but $1100...not happening, regardless if it's "worth it".
CZ is a decent gun, as are the Sig's, but I wanted a striker fire as that is what I'm most familiar with and have trained most with...and for HD in the wee hours, I want a familiar platform.
So...all your choices are proven guns as far as I know...just not for me. And that PPQ M2 .45...really does have a nice trigger, albeit my be a bit lighter than you are looking for.
And to be honest, I shoot the dang thing better than almost every gun and every Glock I own...
