Thanks!

 

I'm no expert, but I'm pretty sure you want one that matches the Carry model.

FWIW, I have a Carry, and I installed the DPM Systems kit. You can select which strength you use.

ETA: Beat by Bobo.

 

I also have the DPM Systems kit in my P320 Spectre Comp and love it.

 

Not to hijack, but what round count does sig recommend changing recoil springs on the m18? I've got a long way to go on mine.

 

5000 rounds for a compact/carry sized assembly, 10000 for a full-sized, if I remember correctly. A lot of folks will err on the conservative side and change at 2500 rounds.

 

You need a recoil spring assembly for a 3.9” barrel, what you showed us is for a 5” barrel.

 

Thank you, Commander!
