Good wheel guns for deep concealment...
I'm not a huge supporter of DA or DA only revolvers for CC over the more practical and concealable DA only semi auto but a few brands/models have merit;
For concealed use, check out the Ruger LCR in .357magnum, the stainless Ruger SP101 .357magnum DA only(my 1st handgun in 1993).
Other decent picks include the S&W model 642, 640, 649, 638.
A larger 686 +P 7 shot .357magnum is a smart choice but the wt may make it seem like a full size sidearm,
.
The S&W K frame 19 & 66 2.5" barrel revolvers with .357magnum or .38spl +P loads worked great for many plainclothes US Govt sworn agents for decades. The US Secret Service, FBI, US Customs, USMS, NCIS(or the NIS up until the mid 1990s) all issued K frame S&W revolvers with few problems.
A CT Lasergrip;
