oooo... me me me me me! I take it I could potentially (at my own risk) use stronger loads w/ this? Do you guys need to install it?

Self install or need to send it out? Any disadvantage to the heaiver recoil spring? What advantages (assuming the one in the gun isn't worn out)?

Self but I will be making a vid for guys like Fly.

None it works fine with EA sub sonic. It may be less reliable with SS197 but I don't care about it working with that.

The same as any other handgun when you install a HD spring. Slide bangs less and brass only fly's about 5 feet instead of 15 to 20.
When I talked to the engineer in detail about the factory spring he noted after analyzing the factory spring that it's not made out of anything special and it's duty cycle is that of any other spring. So anyone with more then 10k on your reciol spring your spring is already wearing out and allowing the slide to beat up the frame.

Can you speculate as to whether these are gonna work with the new longer fsn barrels or would they potentially need something even stronger?

Im trying to figure something out in my head and since Im no engineer and i've thought about this for roughly 2 minutes... Im not sure what to think: when we modify AR57's & PS90's to take heavier loads we cut down the springs a little (making them weaker I assume) and add weight to the bolt. Since the FsN spring is stronger (and the slide which is blowing back remains the same weight) why is it different?

It holds the slide closed longer. It could in theory allow for hotter loads but as always with the 5.7x28 it's the primer is the weak link in the chain.


I don't know about cutting the springs down on a PS90 only adding weight to the bolt. Of which I am still waiting on my bolt weights.

If the primer is the weak point, and you add the appropriate modified parts, could you potentially begin gluing the primers on 5.7x28 and getting HOT loads?

No because the primer cup itself fails and you get pierced primers.

Tangling with glued and blown primers isn't worth it IMHO. Might be bad for the gun over the long haul if nothing worse. The are plenty of good loads to use that aren't pushing overpressure. Frankly, I've never felt the desire to spend all that extra time anyways...

Well people like Wolf make HD and light duty target springs for the 1911.

There are times SS197 WON'T cycle a stock FsN pistol, kinda hard to make a HD spring that it can cycle.

Like I said I tested it with hundreds of Sub Sonic 5.5 ammo and it ran fine. So it should be OK as long as the SS197 is not a low power batch.

Jay, could you reiterate the implications of the HD spring when using a suppressor? :thumb:

They work with 5.5SS already without a can. When you install a can you raise the back pressure.
