How to install Ksc Usp .45 SD recoil/hammer spring

[madlz]

Hi guys. Well im back with some info on how to install SD recoil and hammer spring on a ksc usp .45.

Thanks to kos:

Flip to page 22 on your manual...

The Main Spring Housing (part.87) has to come off in order for you to install the mainspring, or "hammer spring". However, before you can get off, you must remove the Main Spring Housing Pin (part.90). Once that is removed, the housing should slide right off.

The Recoil Spring(part.42) is slightly harder to install. You need to remove a small retention clip (part.45) to swap the springs out . Be careful! Don't break the clip! After that's done, should be easy shit!

Hope that helps.
Cheers!

I get all that stuff except one thing: the rentention clip (part 45). How do you get it off? ive been trying to push it out using a pen to no avail and cannot get it to budge. any light on this?

And as for the Main Spring Housing Pin (Part 90) where is it? the little circle rod at the end of the grip frame?

Thanks all!

i used a pair of needle nose pliers to remove the clip (45) at the end of the recoil guide. as for part 90, yes, knock that out carefully, its a bitch to get out. Once you slide on the new hammer spring, be very careful when putting it back together, the new spring is longer than the old one.

Good Luck!

Glad I could help, mate!

The MSH swap should be fairly easy. Thank god you're not dealing with a gun that's got a leaf spring. God damn 1911s..

If it's anything like the KSC Mk23, there's a small C-clip at the frot end of the recoil rod, use a small slotted jereller's screwdriver to start it off, then needlenosed pliers to grab it and pull the rest of the way off. When installing, hold everything with your fingers (compressed spring, C-clip, etc.) on one hand and use pliers to snap the clip and the rod together. Pretty easy, as long as you don't have to spend any time crawling around on the floor looking for parts.

Use a punch or allen key and hammer the split pin out. I actually did that to my Mk23, rearranged all the stock parts and have a fast cycling Mk23 now, almost as fast if not fast (and shorter) than both my KSC G19s do. Seems to shoot harder now since there's more time for the gas to expand.

is the split pin the thing with the hole in it? if i hammer it out will it go back in like it locks in place or something? your talking about the big metal thing in the middle of the rod right? or are you takling about the one at the end of the rod

The big metal donut in the middle (in front of the smaller spring) has a hole in it, hammer out the pin inside it, the donut will move around freely afterwards.
