And I truly believe thatch ever does custom work or has customer work done (LIKE ME) really care about the factory warrantee.
WE do these things to make the guns OURS and in MOST cases better.
Improve performance and you better bet, that Pro-shooters that work for the LOGO Companies, are running custom insides in their guns.
They might be great shooters, but they are not shooting those times with 6.5# triggers.
Even JM has said that he works with Magna Port to cut ports in his Revos and even some of his early M&P's
Go figure.........
