Recoil spring replacement brand recommendations?

[Rezarf]

Hello-

 

I recently picked up a M1 S90 that is marked HK. I really like the gun. However, it had a hard time cycling field/target loads... which I expected. I know these guns like full power loads. However, after doing lots of reading here, I have come to the conclusion I have to go in and clean up/replace the recoil spring in the stock.

 

I am sure it is nasty, as the entire gun was covered in goop from tip to tail, but after about an hour with a tooth brush, solvents and a good oiling everything went back together clean and running smooth.

 

I didn't get into the recoil assmebly as it isn't covered in the manual.

 

So here is my question, I plan on opening it up, cleaning out the assembly. However, I would like to have another spring on hand in case the one I pull out is boogered up or rusted out. That said:

 

What brand (or model) spring do you recommend for increased reliabilty?

 

I will shoot mostly shot, 00, and slugs... found in 3 gun comps. However, if I can find a spring that allows more reliability with some of the lighter target loads I'd be all over that as well.

 

I have read about the Wolf 25% increased power spring, and there is another spring (stainless) that also seems popular (the name slips me now).

 

Is there anything else to do while I am in there?

 

Thanks in advance-

I've been using Wolff springs for 20+- years with no problems in all my Benellis

Is anyone running the reduced power spring for field/target loads? I would like to try one to see if I can shoot the 100's of cheap rounds I have laying around.

Hi Drew,

 

Check out post #2 in this thread by Remarkable which has a lot of great info about spring selection/replacement

Thanks Hookster, I read that post during my initial search and it provided a lot of great info.

 

I disassembled my recoil assembly tonight and it wasn't as bad as I thought. There is a good bit of surface rust on the spring but nothing that looked like it would impeed the springs operation.

 

However, I did notice the last 3" of the spring was much more compressed than the other section. The compressed section was near the nut that I heated to get off. Not only was it compressed but it was bent at about a 20* angle from the rest of the spring. I am wondering if I boogered it up when I heated the nut?

 

I am still curious if anyone has run the lighter weight spring just for target loads?

 

Thanks in advance- I am learning a ton here... thanks!
