Obviously we don't know about your holster, which makes a lot of difference. I've got holsters that are painful, and holsters where I don't even feel the gun.

But, even with the correct holster for your body, cant can make a WORLD of difference. Before you give up on position, think about different holsters and different cants. The same thing doesn't work for everyone, so I won't preach my go to holster choice to you (Crossbreed). Search the forum for holsters, cant, and your preferred type of holster. There is a lot of information here.
As for 3:00 with summer clothes, wear loose shirts. Nobody will notice the bulge.
