Please don't confuse me with one of these experts, but I say accuracy and feel are more important.
Reliability is by far the most important characteristic of a handgun, so if it demonstrates unreliability, it's out the door. Forget sending to the shop to get it tweaked, shaved, polished or whatever. There are way too many guns on the market, probably at a lower price than you paid, that work flawlessly out of the box. Also, if you pay $500-1000+ for a pistol, it should function flawlessly. If it doesn't, and you have to send it to the factory or the gunsmith, you got screwed!!!
At this point, accuracy and feel don't play a role.
Once you're satisfied that your gun is reliable, you can focus on the other two must haves...accuracy and feel.
