In my mind it's going to be a fete to come up with something significantly smaller than a RAMI and not go to a single stack design? Kinda like the Glock 42 and 43, they're true pocket pistols. My personal hot weather rig is a Kimber Micro .380 in a Holster Store Pro HD IWB, again she's a single stack and only 6 rounds at that. If you can get comfortable with condition 1 the little Kimber or the other mini 1911 looking options from Sig, Colt or Springfield are worth a look. I realize these may not offer the fire power most of you are looking for. I like to have something that vanishes for going on walks with my 10 year old daughter in the neighborhood or out dinner in "nicer" areas.
...I do prefer the design of the Rami BD (if I'm wearing more than a T-shirt and can cover her that's what I carry). I'd probably bite on a single stack shrunken version. Decockers are way cool :-)
Clearly, SIG has proven with their P365 and now SA with their Hellcat....
There is a way to get 10+ in a short magazine, overall pistol height around 4" and still keep the overall width around 1 inch,
without sacrificing reliability. I've fed over 3000 rounds of every type of ammo thru my P365 without a single hiccup.
However, the challenge seems to be squeezing a DA/SA works into this neat micro-9 package. Sure, I'd like it to be hammer-fired and all-metal too. I wouldn't be opposed to polymer, but I'd still like the hammer and decocker. The SIG 290rs hammer-fired pictured in Post #19 above IMHO is very close. It's 3.9" high and .91 wide 5.8" OA-length. Or for that matter the S&W CS9 pictured in Post #1
Add a P-365-ish 1-1/2 stack magazine, RAMI-ish decocker, and make it go SA after the 1st round. CZ has some very smart engineers. If there's a will, there's gotta be a way!
