Witness Match 38Super rechambered to 9x23 Winchester

I have a current model Witness Match 38 Super (large frame ) and a Factory 9mm slide kit that shoots great off the 38S frame. Since i have other 9mm guns, my thought was to have the 9mm barrel rechambered to 9x23 and fit to the 38S frame. There are now a good selection of Hardened parts from both EGW and Henning that are available for this frame if nessesary.

Could anybody recommend a reliable gunsmith to do this work??

I sent 9mm conversion kit to Jim Milks at Innovative Custom Guns in PA. Jim trained under George at EGW for 17 years and has been on his own for an additional 10 years.His phone number is 814-766-3004 after 1pm.

He reamed the barrel to 9x23 Winchester using factory brass and 9x23 JSP ammo. Ammo is fully supported in the the new barrel. It fits better in the barell than if you put a 38Super cartridge in behind as a test. Jim only had the upper to work with, no frame!

Put the ex-9mm, now 9x23 on the 38Super frame, loaded the new Mec-Gar/ Tangfolio 38Super mags with 18+1 Winchester Q4304 JSP 9x23 ammo (124gr, 1460fps & 587ft lbs).

Equal ballistics to a 357 Mag but 1/2 the recoil. Gun weighs 49 ozs. loaded. Very loud but very easy to live with. 40 MAJOR shoots harder than this load.

So now i have a proprietary 9x23 upper for my 38S Match. All iffy safety issues of "can i fire 9x23 thru my 38Super" are off the table. As close to factory spec, as if they did make it! Jim also tighted the ejector and very slight Throating. Ten day turn-around,easy to deal with and fairly priced.

This gun has morphed into one Bad Ass carry gun! + it's dead nuts accurate at 25yds!
