WIN SXP Barrels for FN P-12

[Clarke123]

I have an FN P-12 which (supposedly) has barrels that interchange with the SXP 5 shot combo.
I am looking to get a 26-28" barrel for my FN, and Winchester still carries the barrel, BUT
I would like to know that they really do interchange B4 buying one!

BTW: My interest is that I cannot use the FN P-12 with its 18.5" barrel at Etowah Sporting Clays without a barrel that is at least 21 Inches. Another option would be to have a extended choke tube crafted,,, but that would be my last resort!

Here are some links of interest
