Does a match barrel improve accuracy much in a HP? Or is it simply to improve the shootablility of more types of ammo? I've heard that fitting a match barrel doesn't improve accuracy dramatically like it does in a 1911. True?
hoser, It really depends on the accuracy of your factory barrel, and there is some difference in the factory barrels. I had one not too long ago that didn't want to shoot, and it slugged at .359 - not too conducive to good groups. Bar-Sto's add says their barrels will cut your group size in half, but I think that's kind of a rule of thumb.
