Spectre 9 Is Good
(147g subs) Have ran this can a bit on a 19x and a MP5 clone.. it’s amazing. At 7 ounces with the piston it has a very nice balance on the Glock, and with the trilug adapter it’s practically unnoticeable on the ZF5. Sounds extremely close to the CGS MOD 9 full size which is pretty incredible. No spring tuning necessary to run supers or subs.
