PDP Compact - DPM uncaptured adjustable recoil spring

Hello,
Does anyone know if there is an uncaptured/adjustable DPM recoil spring that works for the compact PDP? The uncaptured seems to be marketed for the 4.5" and longer barrel. Thanks.

Interesting. My PDP 4.5” factory recoil spring is the same as the 4.0 and 5.0”. They only use a polymer spacer to take up the gap.

The guide rod/spring is the same between 4, 4.5, and 5"? So, 4" no spacer, 4.5" spacer, and 5" slightly bigger spacer?

Just curious: If the original factory spring is reliable, why do you need to change it at all?

I don't really need to. I'm just tacticool and like tinkering. Wouldn't mind a little more weight out front and seeing if the dpm does anything positive.
