Mainspring Housing Flexible Hone – Complete Set

The complete Mainspring Housing Honing set includes both the 400 and 800 grit flexible hones and 2 onces of specialty honing oil.

Honing the spring tunnel of the mainspring housing on a 1911 will significantly improve the overall action of your 1911.  Honing of the spring tunnel removes the machining ridges that are left in the spring tunnel, during the drilling process.  This should be a two step process,  first with a 400 grit hone to cut down the ridges and to overall smoothen out the spring tunnel.  The second step uses the 800 grit hone which completes the final polish of the spring tunnel.  The improved finish will allow for superior and smoother action, faster hammer fall and overall improved cycling.
