Nice-lookin' P229! The only complication I can see with this particular variant is the forward slide serrations may act as barbs with some holsters, hindering a clear, smooth draw.
As one who has toted a P229 concealed most of the time since 2007, much of the time from 2004 to 2007, and having toted 5" all-steel 1911s, heavier sixguns, and such, over the years, I find my various P229 pistols EASY to carry concealed. A P229 fits my hand, and FILLS my hand, perfectly, so I can get to pulling the trigger hard and fast, and still get good hits. Heavy? No, I like a bit of heft in a carry gun, because I may well have to fire, if duty calls.
I cannot tell, by the weight of the weapon, if it is in the holster, so why go lighter? It does not print against my usual cover garments, so why go smaller?
Of course, I use my P229s as duty pistols, so life is simpler if I use them for concealed carry, too, and as I buy my duty firearms, I am also getting better value.
Working and living in an urban area, I must pick my shots, so as not to shoot the wrong people and things, and don't sweat the lesser capacity of a P229 compared to other pistols. I usually have an SP101 or a second P229 with me, anyway.
