I bought a used HK45 and I absolutely love this pistol. A friend of mine shot it and liked it so much he purchased one NIB.

Now, After shooting his I noticed that his recoils much softer/smoother than mine, and this got me to thinking.

I have no idea how many rounds were put through my pistol prior to me buyiing it. Recoil springs are cheap so why not replace the spring in mine.

Can someone explain to me how to replace the spring on the guide rod?

I know someone has done it, but it is not obvious to me how the recoil spring assy. comes apart.

Thanks

I believe its captive spring .If the firearm functions good ,I'd leave it be .
If it's really bothering you order one from Hk or just give em a call and tell him your concerns .
Google some pdf armors manual for your firearm .

The only way to get it off is to pinch the forked end of the rod together. This will reduce the circumference of the notched portion and allow the retaining ring to slip over. Be careful though. If the tool slips on the tapered part, it will likely leave a mark.

Fox hound, Thanks for the heads up on the Armors manual...After you mentioned it I tried Google but it kept bringing up Owners manuals. I may give HK a call.

azimuth, I looked a little closer and I see what captures the retainer now. Any idea if the rod is a spring steel or after you pinch the forked end will you have to "pry" the forks back into place?

Holy Moly, just replace the RSA dude.
I think they are good for like 30k rounds.
You'll likely never change it again.

That's what I do, just buy the entire RSA and you're done

I didnt think asking a simple question would get so many panties is a wad.

Sorry to bother you fellows.

Call HKCS - 706-568-1906 , they'll hook you up . It takes a special fixture to do it without screwing up you guide rod or your fingers.

I can't say for sure what the qualities are of the metal, but I think it's safe to say that it was meant to be pinched together. I'd be surprised if the metal didn't return to retention. If I wanted to replace my recoil spring, I'd do it without fear.

That's what the fixture does without screwing up the rod .

What some folks have done is thread the old one off and try to thread the new one on . It can be done , but so can A LOT of things that might be easier to just call the folks in Columbus and be polite. You never know what they might offer ☺ !
