Cs9
The CS9 has been my primary carry gun for the past 10 years or so. It isn't fancy or particularly "fun to shoot". The grip fits my hand well and it feels very solid. The steel slide gives it enough heft to settle down quickly after the draw and after recoil. The smallish sights aren't adjustable for elevation, but it shoots where the front sight points.
I can carry it for months without cleaning, and it will fire with reliability with lint, dead skin, and what have you coating the recoil spring, guide and other innards.
Its edges and hammer are rounded and bobbed to prevent snagging on a garment during IWB carry with a tucked shirt.
It likes Corbon 115gr +P ammo as well as anything and manages 1250fps 15 ft in front of the muzzle.
I have other guns that give me more pleasure to shoot and fiddle with. I don't even handload for the CS9 like I do for my beloved .41s. But day in and day out, it is the CS9 that is with me more often then not. It is a reliable tool, nothing more.
