There are nearly two million Ithaca Model 37s already in the field, and many of their owners would like to outfit them with a new barrel. Just how that aim is achieved depends on the serial number of your gun.
Model 37® firearms with a serial number below 855,000 have barrels that are fixed and non-interchangeable. If your M37 was made before the 855,000 mark (which occurred in 1963), we will be able to furnish you with a replacement barrel for it, but you must send your gun to us for the barrel to be fitted. The process includes machine removal of existing threads, insertion of adapter and re-threading of receiver and re-bluing. Please note that once this is completed you will not be able to reuse your old barrel. Cost for this process is $180.00 for the adapter, plus cost of barrel. Includes re-bluing at no charge.
Model 37s® with a serial number above 855,000 have interchangeable barrels (except for some Deerslayers), but often still require some custom fitting by our gunsmiths.
The thread pattern that we utilize on our interchangeable barrel field guns is the same pattern that was used by Ithaca in New York after 1963. However, Ithaca in New York used manufacturing methods that created differences between their firearms that made their barrels less than truly interchangeable. So, while some of our barrels may fit post-1963 guns off the shelf, others will require at least minor modifications to fit correctly. You may send your gun to us for the barrel head spacing to be checked and tested, and there is no additional charge for this service, or have your local gunsmith perform this fitting.
