P320 Compensated Pistols

I used the DPM recoil reducer. There have been great reports from others and I say it is the way to go. It comes with 3 different weight springs to see which one runs the best. I didn’t want to buy multiple springs to tune and then just have extra springs without needing them.

I have the DPM kit as well on a full size 4.7 build with a Armory Craft comp. I am settled on the middle spring and small cap shooting 115 gr. ammo.

I am building a P320 Comp pistol and had a question for those of you who may have done this. What recoil spring did you use in your build? I am going to us the TXG grip from Grayguns, I have a Sig subcompact slide with Romeo 1Pro coming for it and I bought the Parker Mountain Machine dual port comp and barrel. Does anyone know if the the regular factory recoil spring for the subcompact will work with this?

Factory recoil spring will not work with a dual port comp. You will need to get the DPM springs and put in the lightest (shortest spring). Start there.

DPM springs for X-compact (3.6" subcompact): DPM Sig Sauer P320X Mechanical Recoil Rod Reducer Systems MS-SI/25 Gun Make: SIG Sauer, $8.00 Off w/ Free Shipping

If you are still having frequent stovepipes after breaking in with a couple hundred rounds, then refer to this video from SigGuy:
I had to snip some coils to further lighten the spring strength. Now my dual port comp runs great.

Thanks for all the info. everyone I appreciate it. I was hoping I could get away with the regular SIg OEM spring but it doesn't sound like that will work so I'll order a DPM one and go from there.
