I just got one of these pistols and would like to replace the stock recoil, firing pin and hammer springs. Browsing the Wolff website it does not have a listing for Rock Island Armory. Does anyone know which spring set would be compatible? It does have a listing for the Delta Elite 10mm. Would these be compatible with the RIA 10mm?

I too have recently purchased one of these pistols, and would like to know this answer as well.

Well apparently the Delta Elite recoil spring is just the standard 1911 spring. It's placed in a separate category by Wolff because it replaces a dual spring setup that comes standard with the Delta Elite. The factory standard for the Delta is 23 pounds so I'm going with a 22 pound spring. There is also a calibration pack that contains 18.5, 20, 22, & 24 pound springs.

Yes, the Delta springs are the ones you want. I'd go with a 20lb.... 22lb at the most.
