I use h3-H4 for my 9” and 8.3” always suppressed. With your longer barrel I suspect the H3 would be good. But I would test with an H2 if firing supers without a can. Not sure a single buffer weight is optimal for all weight bullets with and without a can.
Correction: My 8.3 has an A5 tube with H3 buffer. Carbine tube with H3 on the 9”.
