Milt Sparks VM2 and a quality gun belt. It works very well with the G27 but I have one for G29 and a Smith 1006 as well. It's the most comfortable rig ever (why I own THREE of 'em despite the damn near year long wait there used to be to get one!). Conceals extremely well. Cost is on par with Galco, quality is on par with Alessi (maybe a little less attention to detail but only where it doesn't matter). By far the best rig for the price.
Trust me, you won't regret it. I'm not the only one that feels this way, they have a following. It's imperative you get a good gun belt for it (they make a good one) and I'd recommend whatever you carry, that the thinner weapons conceal better. A good rig like the VM2 will allow for full size pistols, length ain't so much an issue as width and weight.
If you carry a 1911, just go on and quadrulple the option because Milt Sparks sorta caters to the 1911 crowd. But VM2 and others fit damn near anything.
For Smith 1006. Hosehide with leather belt loops. You can tell the pistol sorta sits recessed behind the loops... It sits like this on your hip too and the belt goes over the tucked in holster and it all just becomes part of your hip, no movement with these, one hand reholster thanks to the metal reinforced lip. There is no better fit and there is no way to adjust these, they don't need it. Been using one for fifteen years now and it works like new still. Did I mention they were comfortable too, for like all day wear? This is important for CC, if it ain't comfortable, you'll quit wearing it. Remember we wear these things ALL DAY and if everything goes GOOD, well, we NEVER use 'em, so just keep that in mind.
(I'm actually selling the 1006 and all the gear pictured, but it's the only one I have of a pistol and mags in one of the rigs so I figured I'd post it for you so you could see how they sit). Note the tab in the back that protects you from the safety, etc. digging into your side.
