The Shok Buffer is a Polymer ring made to soften the slides slamming into the guide rod and thus the frame. Believe that is a Wilson trade mark nowadaysFlyer said:Well, what they're talking about is the recoil spring rod...
:lol: Flyer : my PD has this part.[ Buffer ] The recoil rod is a 5 part assm [counting spring ], what looks like the flared seat at the barrel link end is actually a seperate piece of hard PLASTIC ! The larger end at the link unscrews . [ rt hand thread-!! caution- some type of thread lock agent was used from the factory. ] The factory recoil spring rate was only 12 lbs., so the buffer was used to protect the alloy frame. Numrich Arms, [ Gun Parts Corp ], has them listed ,but have not had any for qiite a while. [ Part # 128690 ] Units like Wilson buffers can be made to work, but don't stand up very long. I tried to find some for the PD , and only could locate 4 used ones on Gunbroker.com, W/ 2 Wollf springs,they went for around $75.- NOT TO ME!! I installed a spring .023" larger wire dia., 1 less coil, approx 1/4" longer free length. Nothing to check with but I think its about 17 lbs. My buffer is in good shape and I want to keep it that way. One more caution: if you mess W/ springs, check for coil bind. Barrel bushings are hard to find and not built for that kind of pressure. Don't ask how i know this. Hope this helps, MaGee's husband.Flyer said:Ahem...
The issue was that of a BUFFER... of which the PD doesn't have one. It's got the standard 1911-type spring guide rod.
And almost ALL 1911s have the standard bushing-spring-rod arrangement... it was THIS I was referring to as the "guide rod".
Yes, there are some 1911s that have been modified to use a full-length guide rod... and I wouldn't touch 'em with a ten-fool pole.
