Springfield 5" Prodigy: proper recoil spring weight and replacement interval?

Bye_Felicia Joined Apr 2003 Posts 18916 EE 100% (187) MO, USA	Posted: 12/2/2023 11:40:03 PM EDT My google-fu must be weak these days. Needing help with which weight recoil spring I should pick up for my 5" Prodigy. I just want one on hand as a spare. I'm up to almost 2000 rounds and know that I'll likely need to replace it eventually if I start noticing problems. I mostly shoot 115gr at 1200fps. (Fiocchi factory loading)

I’ve actually dropped to a 9 lb in mine for ~200 rounds out of the 1k I have through it. I will say though that the factory 10 lb spring is shorter OAL than a Wolff or WC springs I have on hand (12, 10, 9 lbs).

I was having issues with mine, and the issue turned out to be heavy duracoat on the rails and the disconnector dragging.
Before I figured that out I bought all the recoil springs, 9 to 14 lbs.
I think with all these springs I will find a perfect balance of function and control with a given load.
Mine just runs like a scalded ass ape with the 12 lb, I’m going to try the 11 and 10 next time out.

I have have two 1911 9mm pistols.

The first is a Ruger lightweight commander that came with a 10 pound recoil spring. It would barely pass over the disconnector. It ran very well with a 12 pound recoil spring.

My second is a Springfield Armory Prodigy. I am not sure what the factory spring is but I replaced it with a 13 pound spring and it runs wonderfully.
