Changing Main Spring in Pardini SP22

Hi all,

just wanted to know if there's any special tools or technique to remove the main spring in a Pardini SP 22.

It's under some pretty good compression as installed, and I want to know if I simply push against the threaded barrel fastener up the "L" shape slot and hope that releases the compression on the spring for removal.

Can anyone expand on the technique for removal?

Thanks

You mean slide spring?
If yes, thats removeable with normal cleaning procedure.
If you exchange slide spring, I'd also exchange the buffer. Which is harder to do ;)

No, it's the spring that is located behind the trigger, and is in compression against a pin or dowell. The spring is .043" cross section x .250" o.d. x 1.5" long. ... You need to remove the grips to access it.

I was successful in removing that spring, but word to wise, wrap a towel around the pistol frame to collect flying objects! ... don't ask me how I know!

Just out of curiosity, what problem did you hope to address by replacing the main spring?

Thanks!

Hi Orion,

Well, just doing a basic tune-up and thought to do a thorough cleaning along with spring replacements. I was headed up to Maine to visit with friends and on my way is the exit to Gray, Maine so I stopped in at LGI and chatted with Larry Carter and puchased a few replacement springs.

Now I wish I never pulled that damn spring out as it's a PIA to put back in place due to the amount of compression required on it while manuevering it back into the "L" shaped machined slot. ... So far I'm unsuccesful with my fingers trying to push it into place. ... May require a special radiused tool to capture the diameter of the pin and some leverage.

I won't be doing this one again anytime soon.

Thanks! ... I ended up having to fabricate a plastic (delrin) pushing tool to wrap around the radii of the pin to give me some leverage while pushng it into the "L" machined slot. Worked like a charm.
