I was looking seriously at the HK 45 for myself a while back. The deal breaker for me was that it had such a low capacity for a full-size gun. But since you live in California, the capacity would be fine for you.
I personally would not buy a Taurus I've just heard too many complaints.
Full-size Ruger autos fell like bricks in my hands, though I love their .22s and revolvers.
I love my Glocks, so the G21 would be on my list.
I don't like the high bore axis on Sigs that's strictly a personal preference. It looks like the Storm might have the same issue, though I've never handled, much less shot one.
I like the M&Ps I have shot, though I've never shot any in .45.
I've never even handled any of the other three, though I do know in general how a 1911 feels, and I like it. I've never fired an LDA 1911, though.
I have fired XD45s, and they are sweet.
Happy shopping, and happy shooting!
