Chances of finding Parker Trojan barrels??

[Dean Romig]

You would probably have better luck just finding a Trojan with decent barrels but with other issues that would make it affordable.
Does yours have the rib extension?
You could even buy a set of decent fluid steel barrels from another grade and have them fitted with the Trojan forend lug and the correct rib extension (or remove it to fit a Trojan frame that is not inletted for the rib extension, depending on which style you need) but this could run into more than the gun would be worth.
