TSO .40SW conversion to 9mm

[M4rc310]

Yup can use .40 in 9mm mags but not 9mm in .40.

Exactly - I already proved this by trying to load some 9mm rounds on the 40SW mag.   The leaps are not narrow enough and the rounds will slip through.  I will need new mags for sure.

Just an update here: the barrel fitting was a success!  The TSO is a happy dual caliber (40SW and 9mm) beast now!!!!

I searched on this topic before posting the question and found some comments towards confirmation of this - but would like a definitive answer before I pull the trigger and buy a 9mm TS barrel.

Can I have a confirmation here that a TS 9mm barrel (PN 047004940706) can be fitted to a TSO chambered in 40SW?  And that all I need is the barrel and a gunsmith to do the fitting to me?  And no other part...

Thank you guys!

I have been wondering what to do with my TSO 9mm now that I have A01-LD. I also have a TSO .40 to shoot major. I may have to look into getting a 9mm TS barrel. I haven't decided yet if I want to sell the TSO 9mm yet and put that money towards something else. Besides plinking, I wouldn't use it for any matches since the A01-LD had been approved for the production class.

Have you had any issues yet after fitting the 9mm barrel to the .40 slide?

Any suggestions on what to look for in a gunsmith to ensure this gets done correctly? What is a reasonable cost for this?Thanks

I sent mine to CZC.

I have read that some conversions require a 9 mm extractor to run reliably, and some don’t.  Probably depends on tolerance stacking.

I got a message but can't reply for some reason concerning the 9mm barrel. Anyone know why I can't reply?

When you want CZC to do the modification, all you have to do is send the slide. I would call CZC first to see if the have a barrel in stock. There is a work order form you need to send out along with the slide. I sent my slide via the USPS because it got there faster and was cheaper than UPS.
