I have a very nice .40 cal Apexed M&P 1.0 with 4" barrel I'd like to "convert" to 9mm (to get double duty from a good triggered gun).

I understand all I need to do is replace the 40 barrel with a 4" 9mm one and change mags to 9mm.

So...what is a 9mm tube going for these days and who has them?

I see Apex has "semi" something or others (some fitting required?) going for $190ish. Is this the going rate or are there less expensive alternatives. I don't need match or threaded for a suppressor, just a nice working barrel that fits.

thanks.

I bought mine from Midway. About $80.00, as I recall.
