I just bought a P320 45ACP full size LEO trade in. I'd like to replace all the springs but am having trouble locating a vendor. Would appreciate any suggestions on where I should look.

Have you considered Sig? I’d think they have the parts.

All I've seen on their site is recoil springs.

Not sure exactly which springs you're looking for, but for what SIG identifies as 'small parts' I've used Top Gun Supply, SIG and Midwest Gun Works with much success.

Top Gun Supply --> https://www.topgunsupply.com/g...facturer%5D=6&page=1

SIG --> https://www.sigsauer.com/partpicker/p320-parts-picker

Midwest Gun Works --> https://www.midwestgunworks.co...:brand:Sig$2520Sauer


Keep in mind that with these 'small parts' availability can be hit or miss sometimes, and the shipping cost(s) can add up quickly! I'd put a list together and check all three, and figure out the best source (or sources, if they're not all in one place!) in order to get everything on your list at the lowest 'delivered' cost.

NOBODY has ever complained about the service they get from Top Gun Supply...Just Sayin'

Good Luck

Thank you, nhracecraft. I want to replace all the springs when I clean/disassemble the FCU and slide.

Try calling Sig and asking. They do not list every part available for every gun.
