Just enjoy your 586 L Comp.

I have a S&W M19 Carry Comp 3" and a 2 3/4" 66-8. Can't tell any difference in "Flash or Blast". Recoil seems a bit moderated with the Carry Comp.

I've had a 6" Magnaported Freedom Arms .475 Linebaugh and a custom 5" S&W M29. Also had a ported S&W 7 1/2" 629 Stealth Hunter along with the aforementioned S&W 19 Carry Comp. Never found "Blast or Flash" to be an issue. Never had a problem cleaning ports.

On several occasions with different people a side by side comparison of the magnaported FA .475 Linebaugh and an unported S&W M329 .44 mag, both with top end loads - H110 in the 475 and A2400 in the M329 - consensus, the M329 was quite a bit lowder.

FWIW,

Paul
