I really want to get a new pistol but i am at a crossroads. The two top contenders are the HK USP and the Sig Sauer P226, now either way they both come in 40S&W which is what cal. I want. Now if i get the Full USP tactical it is supposed to have better sights and a threaded barrel but on the Sig is about 3 to 4 hundred cheaper. What do you think?
