Washer for captured flock guide rod

[RMM]

Yondering,

Are you still able and willing to test a Wolff spring setup?  I just ordered a Wolff guidrod and 22 pound uncaptured spring.  I would be willing to send it to you if you could test it and add it to the existing graph. 

I still wonder if we are messing with things that we shouldn't be in the G20 by switching from the stock polymer guide rod.  You can tell that it flexes quite a bit under recoil, whereas the metal rods are probably flexing much less.  I wonder if somehow this introduces additional binding somewhere in the system, especially with the polymer frame flexing under recoil.

I think that the dual-spring setups probably aren't as sensitive to this change, as the polymer setups are already much more rigid IMO than the single spring style.

I do have a brass stacker captured stainless guide rod with a 22 lb ISMI spring that I have used back-to-back with the stock spring.  The spring does not feel that much stiffer when racking the slide, but the "friction" of it does feel/sound slightly different.  The problem is that I don't have any objective way to measure the difference and I know that my perceptions are often incorrect.

Although I am not certain of this, I do think that in some instances the slide is unlocking early enough to bulge the brass beyond the normal chamber support.  I am not sure how much additional preload would be needed to change the timing enough to make any difference, or if it is even possible to do so without destroying the reliability of the gun.  At some point, I think that we just might be asking too much from the platform and cartridge.

Yes, no problem. I'll send you a pm with my address.

I don't know if the flex of the guide rod is a factor, but the stock polymer rod is slicker, so the spring doesn't stack and bind against it. This is plainly visible on my spring tester.
