I strongly recommend the Sig P-226.
I bought one in .357 Sig about a year ago and immediately upgraded it with a Bar-Sto .40 S&W fitted barrel. Changing the caliber is as simple as inserting the desired barrel; everything else -- including Sig's magazines -- is interchangeable between the .40 S&W and the .357 Sig.
The P-226 is extremely accurate, reliable, durable, and designed/manufactured to the highest quality standards. With over 2000 rounds of all sorts of factory new ammunition though it, I have had zero jams, failures to fire, or any other type of problem.
The full-size P-226 has excellent ergonomics and is suitable for concealed carry, for home defense, for general plinking, and for competitive target shooting.
I rate the Sig P-226 as significantly better (principally accuracy) than my Glock 23C (in .40 S&W). Sig produces outstanding firearms. You will be happy with the P-226.
