For what its worth, and worth exactly what you've paid for it....my list is:
Colt or equivalent 1911 pattern in .45 acp/Super .38/9mm/10mm. I've owned and shot 1 or 2 or 50. They are my go-to after a few years of trying different things. Different brands, all have different characteristics. But they all fit me.
Browning HP in 9mm. Awesome pistol. I've owned a few but currently don't have any. Always got sold to fund a new 1911, and because they just didn't feel as good to grip or shoot (as my 1911). Can't have it all at the same time...
A true blue P.38. I've bought and sold many 9mm pistols over the years, haven't managed to OWN one of these yet. But those I've tried have me sold. I'm still looking for the right one. It fits and points well for me.
A Gen 3 Glock. I've only owned 2, both full size G21 (.45 acp). Great shooters, but again sold because of my fascination with the 1911 platform. Wish I had them both back though.
I would love to try a Beretta 92, for the simple fact that I have a large pile of 9mm, and because Spenser For Hire brought it to my attention. It also has a few parallels to the P.38, ergonomically.
I'm also a big fan of early-mid 20th century firearms, so most of the current offerings leave me cold despite their competence in shooting sports. The exception is the Glock, mostly because of the age-old rivalry between it and the 1911 that the internet has brought to my attention. As for that, I'd call it a draw in my limited experience.
