MPX pin and weld,,,

[texasdawg]

  Was wondering if any one has, say a 5.5 inch barrel with the extension pin and welded to make it a 16.25 legal barrel for USPSA on a Sig MPX?  I have a Taccom 5.5" pin and welded barrel on my ar9 and like the way it balances. I have installed a carbon fiber handguard on the MPX, but it is still end heavy. I was looking at starting with a ILWT 5.5" barrel and going from there,,,

my mpx started life as an 8" pistol and it's pinned and welded with a taccom aluminum extension and it is much less front heavy than the pcc version, for better or worse

Thanks for the input,,,
