Are you asking which one to go with?
There are hundreds of people out there selling insert kits or even inserts, singlely. So you can build a kit with what you want/use or have them all to cover any possibilities. Either the SP original ones, the SP stainless ones and then the Empire inserts.
There have been many insert type barrels made, from the original OTP G-1 Dream series, that used sized collars at the beginning(at the breech) of the barrel, to Scepter, Freak, CCM, SM1, i think Bob Long did one and probably a couple others. The only one that has been "universally" accepted has been the SP freak. So the others are more kit specific, where any freak barrel will take any freak insert.
