Both of mine ran/run subsonic out of the box with the reduced spring installed. Remington and Aguila.
You might try purchasing a replacement light spring and heating it with a torch to red hot. Allow to cool, oil, then see if it will cycle. If not, clip a coil, and retry.
I could make a list of a bunch of guns i have, or "have", or wish I had. Why would one feel compelled to provide that infornation freely? Do you feel the need to show off? Is it some immature game of oneupsmanship?
Why do you feel it necessary to list your guns?
