I`ve noticed Bar-sto, and other makers, offer pre-fit, and "smithing needed" barrels. I`m planning on buying a Bar-sto for my LW Commander, and having a good smith install it. (along with a trigger job, and new sights) I`m using it for carry, and informal target shooting. (I LOVE accurate .45`s!) Is one better than the other, for my application?-Thanx
