The usual answer for that, based on workmsnship, durability, and extreme accuracy, is the SIG P-210. Costs over $2,000 usually, when you find one in the USA.
But is is NOT the most practical. Some can't operate the safety well in a firing grasp, and the magazine release is in the butt. Capacity is just eight shots.
Practically, I'd go with the CZ-75/85 or the Star M-30. The Browning Hi-Power is also good, but wears out sooner if shot a lot with hot ammo.
