While I am not a big fan of the Glock 19's, when you compare the size, weight, capacity, reliability and simplicity....it is hard to beat for concealed carry, especially when compared with a 686.
I have a 686+ with a 3" barrel that I purchased for possible CCW, but it resides strictly in the safe because of its weight, bulk and cumbersome profile.
I usually conceal carry other pistols, but I would have no reservation carrying my Glock 19 gen 4......
