OP - I feel your pain and have dealt with this issue for about 15-20 years. I've finally arrived at a G17.5 in a Galco Ultimate Second Amendment horse hide rig at 12 noon for the most comfort and least amount of printing, even with a t-shirt, because the gun rides deep. Absolutely counterintuitive I know, but I've been trying to make a G27 and/or a G26 work at about 12:30 and while the printing issue is practically nonexistent, even under a white or gray t-shirt (the acid test IMHO), sitting down for any stretch of time resulted in, first: femoral nerve pain, and second: a numb right leg.
Following the advice of GT members, I moved the latest 26 to high noon and that solved some of the problems, but when I asked about larger guns being more comfortable in a GT thread, I got a lot of positive responses, so I bought a G17.5 and it feels better while sitting. Standing and walking has never been a problem with the 26s or 27s, but now I think I can sit for longer periods of time with the barrel/slide directly on the center line.
I haven't tried it through an entire restaurant meal or movie (haven't been to one in a few years), so I might have to eat some crow, but for now I think the bigger gun is MY answer. I understand the idea of G19 in the summer for less grip printing, but I'd worry about the femoral nerve/artery thing again. The belt post was an excellent idea and one I might have to pursue because who cares if your belt buckle is right on the gig line when it's under a shirt anyway?
PS - I also tried a G34 with my Galco holster but it poked out a bit too far and I felt like a porn star for a while as I conducted the test. Although the LGS owners didn't make a big deal out of my big deal because they knew what it was ... just a gun barrel.
