[Recoil spring set up for subcompact p320 slide]

I got the pmm ultra comp and a sc norrso slide. With a sro mounted the subcompact recoil spring will only cycle with +p ammo. lve hand cycled 200rnds and went through 2 boxes of 124 nato with Jarrods advice with no avail. They should offer some type of reduced recoil spring. The comp takes so much energy away on normal loads and wont cycle light ammo. Im going to attempt to cut the inner coil in the meantime.

Progress:

The bad news is, I don't think a single recoil spring setup is feasible with a P320 SubCompact.  There's barely enough room for a 4" let alone a 3.5".  

I took some measurements on my p320 compact/carry slide.  There's only .866" of space for the spring when fully compressed.  My adapter ring eats up 0.100" and another 0.070" for the base of the guide rod.  That leaves only .696" for the spring at full compression.  My thinnest ISMI 13# G19 spring is .896" fully collapsed.  However, after digging around, I saw that the original 4" P250C used a round wire spring with only 12.5 coils.  It's similar to the springs used in the P225/228/229 series which look very similar to a chopped 1911 recoil spring with much steeper helix angle.  So I ordered a 15# Wolff P228 recoil spring.  In the meantime, I made an adapter plug from some 317 stainless rod.  I based it around the dimensions for 1911 spring plug but I added a chamfer inside the rear to prevent the recoil spring from hanging up as it kinks on the rod.  I'll test the fit of the plug with a Glock spring and guiderod tonight.

That's as far as I am in this plan. PMM 2 port with the Faxon barrel Norso slide (not sure of optics)

 

I was toying with the idea of compact slide  and barrel and letting it stick out to pick up a little barrel length but im not sure

 

Im assuming you need a subcompact guide rod system. PMM may have a recommendation on this.

I am putting together a p320 with a subcompact slide and compensator.   What recoil spring and guide rod setup should I use???  I would like  to be able to run 125pf loads.

I have also preffered light spring setups on my 2011s.

Thanks

Not sure if this has been answered in this thread, but DPMS does make a subcompact guide rod system with 3 different springs. You have to order it from their website, and it's shipped from Greece. It's not available from US third party sellers like their compact and full size systems. I have one and it's great with the PMM dual port comp.

Starting in 2025?  Tongue and cheek but this does at least appear to be a very interesting option

I was thinking the same. Probably vaporware. We may see it by the next presidential election lol
