I picked up an EFK barrel for my Browning Hi-Power. (Somehow, the factory barrel was damaged -- lands damaged near the crown -- and a factory replacement barrel was very expensive.)
I found that the EFK shoots as least as well as the factory barrel did before it was damaged. That EFK barrel is really nicely finished -- a gorgeous barrel -- and in my case, it was a straight drop in, which is not always the case with some of the after-market barrels.
