Favorite Concealable 9mms, eh?
Very good question, as I love the 9mm round.
It depends on what you mean by "concealable".... 4 categories:
1. If you mean "smart carry/ankle holster/pocket carry", when thin-ness AND small-ness are paramount, the answer (for me) is the Kahr MK9 (9093 BOX). $389 new retail if you look - much less than other Kahrs. Or, better yet, the Rohrbaugh R9 would be the ultimate if you can afford it. Also good would be the Kimber "Ultra RCP" or Para-Ordnance "Covert Black Carry" 1911s, *IF* you could get them to make one for you in 9x19 (possible but not likely without a lot of $$). The latter choices in .45 acp are nice however.

2. If you mean "tuckable IWB/other IWB/Deep concealment", then the answer could be those from category #1, or you could also add larger but thin guns like the Sig 225, 3.5" and 4" 1911s in 9mm such as the STI "BLS9", other Kahrs such as the K9, or HK P7M8 or P7PSP - these would be excellent slimline choices, and perfect for tuckable IWB ("deep concealment"). Of course, YMMV since many carry 2-stacks IWB - I find that way too uncomfortable and requiring a different wardrobe of pants & belts.

3. If you mean "belly band/fanny pack/purse (man-purse?) carry", where you can go thicker without printing and thus get more capacity, but need small overall dimensions, then the answer is the CZ 2075 Rami, Springfield XD subcompact (or its more expensive yet inferior cousin, the Glock 26), Walther P99 subcompact, or compact 5-shot 9mm 2" revolver, if ultimate reliability is your premium.

4. If you mean "standard/primary/strong side or cross-draw/OWB (paddle or BS) holster - with covering garment", the are a thousand choices (and a hundred *good* choices) in this and the full-sized categories, but I like the CZ 75 compact PCR, or CZ P01. Or for a little more, maybe a Sig 228/229 (preferably the 228). Or the Bersa Thunder 9 if you're on a real budget (real good gun value).

However, I should point out that in category 4, with proper clothing, *many* people find that a full-sized gun is no harder to conceal than a compact such as those mentioned, and of course you'd add sight radius and so forth. BUT, my personal thoughts on this subject is that *IF* you do run with full-sized for primary, you're better off with a single stack like a 1911 or some such, because I find that a full-sized AND 2-stack gun prints too much in the bottom-of-grip area into your covering garment (for me to be comfortable carrying with same out in public). So I like a compact 2-stack like the CZ P01, OR a full-sized 1-stack, but prefer the former, due to capacity reasons and available offerings, and I have no printing issues with proper jacket or sweatshirt.
So, IMO, the choice all comes down to EXACTLY HOW you are going to carry, and are you going to carry in only 1, or 2, or 3, or all 4 of the above carry modes, and depending on the answer to that, how many guns (budget) can you get to fill the 1, 2, 3, or 4 roles? If the budget only allows 1 gun, AND you want to carry in all 4 modes that dictate dimensions, then you'd best get a gun in category 1. If you're going to carry in all but category 1 (2, 3, and 4), then something in category 2 will best fit your needs. If you're going to carry in categories 3 and 4, but not 1 or 2, then something in category 3 will fit your needs best. If you're going to carry only in cat 4, then something from cat 4 will be best. If you have the budget for 4 or more handguns, then it doesn't matter, you can get 1 or more for each category (size range), or better yet, 1 for each specific carry mode, if you're willing to train enough so that you know how to use the different manuals of arms if/when you need to use the gun.
I have cat 1 covered, with the Kahr MK 9093 BOX, and cat 4 covered, with the CZ 75 Compact PCR. Both have the same *essential* manual of arms (just point and click - no manual safety). If I ever get a pistol to dedicate to category 2 (tuckable deep concealment), then it will be an HK P7 (also point and click). If I ever get a pistol to dedicate cat 3 carry, then it will probably be the CZ 2075 RAMI pistol, although I dunno, since it's got no decocker - may have to run with the Walther or XD instead. As it stands, the Kahr covers cats 1, 2, and 3. I know, I know, over-analyzed, but hey...
