Your advice, opinions, or derision would be greatly appreciated
Well, this is not the Borg, there are solutions to fit nearly everyone out there.
Which is good in one way--there's a Goldilocks out there for each of us.
It's bad in that you may have to eat a lot of too hot and too cold porridge and sleep in too many too hard and too soft beds to find the phule thang.
Sometime, though, the joy is in the search.
I will admit my bias, though
365X with factory Romeo Zero sight.
It's the XL-length frame, so it uses 12 round mags natively, no need for pinch-causing adapters or the like.
It conceals easily enough for me, although that CrossBreed SuperTuck helps
It's the smallest of the fry in my net right now, and there are a lot of examples that are similar in dimension
(Commander, top center; Officer's right; 365X left; Colt 380 Government, bottom center.
Now, for "easy to rack" that list is a bit different.
That Series 70 380 Gov't is like butter, my new Astra A-70 is also sweet (likely as much to having been used a bit)
Mind my other 'easy' slide is not really an EDC candidate:
A 1903 Colt in 32acp
The real knock to haggle about with the SIG is on mag prices. You are looking at US$40-45 per each (about what Astra or 1903 mags will likely cost me).
But, there are plenty of options for holster and mag carriers with off-the-shelf fit.
This will be true for LCP. helcats, and all the rest, too. I did me; you'll have to do you.
