Our semi fit barrels are over sized compared to the factory barrel. The reason we do this is so our barrel locks up better and shoots more accurately than the factory barrel. In most cases our barrel will require some minor fitting. We do not make drop in barrels. We feel that you should get a better, more accurate barrel than the factory and you cannot get the higher standard of precision and accuracy from a drop in barrel. The fitting usually is very minor filing of a few areas. This is in our opinion a good thing, as you will get a better fit. If you have questions you can give us a call and we will be happy to help, if we can. We do offer the fitting of our barrels if need be.
