I realize that after mastery of the fundamentals, training and practice, most semi auto handguns from a quality manufacturer will provide "adequate" combat accuracy. I also realize that accuracy will vary somewhat with each gun of the same type. But some brands have got to offer more accuracy than others. Lets assume a price ceiling of $2000. While still retaining acceptable reliability, what make, model and caliber pistol would you expect to produce the best practical accuracy? Thanks!
