Perazzi barrel fitting question MX TM HiTech

Do all Perazzi barrels interchange with the same model? Will MX3 barrels all interchange with other MX3's? Also TM's etc?

I don't need gunsmith names. Just need the answer. TIA

 

Some do and some don’t. You won’t know until you try but I would have it fitted anyway.

 

TM barrels will go on TM they are single barrel guns
MX guns type 3 round body mx 3 early mx8 will fit each other
Type 4 MX guns will fit each other all will require fitting

 

Type 3 isn’t a round mono block, it’s a square monoblock with different forend iron/lug

the round monoblock guns are a different animal
