I frequently run errands, and I carry everywhere it is legal. Sam1911 hit the nail on the head:

Good belt, good holster, move the gun to a position where it is most comfortable when you're doing most of whatever it is you do. If that's sitting, move the gun to where it is comfortable when sitting.
For most of us that's at the 3:30-5:00 position at/behind the strong-side hip.

. . . .There's no way I can wear anything like this Remora OWB at 10 or 11 o'clock while sitting down. What really Is nice is that I jogged with it for 30 min. the other night and the Makarov didn't budge one bit.
I've got a bit of "Dunlap's Disease," (where my belly done lapped over my belt . . . ), so I can't imagine carrying at 10 or 11 o'clock. I carry at about 4 o'clock. That means that when I'm in the car, I'm leaning back on my pistol, rather than having it poke me in the gut. My most frequently-carried gun is my G19. Most of the time, I carry it in a CBST, which is
ridiculously comfortable. However, I do have a variety of other holsters, and I use the one that meets my needs best at the time (CBST or leather OWB for suit-and-tie occasions, Kydex for the woods, etc.). I've amassed 4-5 holsters for my G19 over about 2.5 years, picking them up here and there. I've definitely gone through some trial and error in holster selection.
I recognize that handling an unholstered firearm carries some increased risk of an ND. Nonetheless, I am one of those folks that actually does unholster the pistol when I remove it to go in to some gun-unfriendly location, like a courthouse. However, most of my holsters have belt loops that make it difficult to take off in the car. And I'm not interested in standing outside of my car, fiddling to get my belt back on in broad daylight. The gun comes out of the holster and goes into a small safe while I'm away.
I'm going to suggest that you try moving the gun around back. Somewhere between 3 and 5 o'clock if you're right handed, 7-9 if left. If shifting to a new carry spot doesn't solve the problem, you might have to go with a different holster. (None of your complaints seem to revolve around the belt, so I'm guessing that you have a decent gunbelt. Yes?) I have to admit, as well, that the Remora really doesn't look that comfortable.
