Because of recent health issues (I prev got into it), I can't carry my 2.5-3lb loaded fullsize 92FS IWB right now. Anyway, I REALLY like my M&P Shield. And, pocket carry with it is very convenient. You can put your hand in your pocket anytime you want. Very easy to access the gun if need be.
I'm also very confident in that particular gun, as I've done much 1 handed practice and 1 handed double taps (I have found that on most guns, I do doubletaps better with 1 hand than with 2 (for the placement of the 2nd rapid fire round)
