"O" Rings for the Hi Power

[ToddSig]

there was an "O" ring discussion a few weeks ago on another forum which drew my attention.I looked back over past posts, and found several members stating that the 1/4" outside diameter and 1/8" inside diameter sized O ring worked well.

I searched on Amazon and found a bag of 1000 "O" rings for $10.00. I figured even if they sucked, not a big investment, and easy to replace an used deformed one wit a new one. They fit perfectly (see images, last image of a MKIII stock grip, with O ring installed, so far no issues with grip screw standing proud), but cant comment on the longevity just yet.

Since I have this big bag of O rings I will probably never use, if anyone wants a few to try out, DM me with your address and I will mail you a few, postage on me.

Hello, Todd - Thanks for the tip and the detailed photos.

If you find the O-Ring a bit thick when used with Thin Panels, try the 3mm I.D. x 6mm O.D. x .5mm Thick, Red Fiber Insulating Washers that's used in electronics.

For 1911 Grip Screws, I use O-Rings that are 3mm I.D. x 1.5mm CS/Thickness (cross-section).

Here's an old thread on the Red Fiber Insulating Washers. highpowercollectors.proboards.com/thread/674/grip-screw-washers-hi-power

Thanks for the tip and thread on the Red Fiber washer. I have found so long as the grip countersink hole is deep enough no problem. But as you mention, thin grips are more of a problem. I found the Navidrex Micarta far to shallow to use, Spegel the screw head is slightly proud toward the back side, inner side OK, same with Hogue wood. Spegel Uncle Mikes, Guuun Grips and a set of VZ, along with stock grips, the rubber was fine.

I do recall an earlier post from somewhere, where the poster mentioned caution using the rubber O rings on wood grips...a tendency to crack the grips. Anyone hear of that?

I found the Red Insulating washer on Amazon (different from what is listed on the other thread Bob references, those were delivery for late Feb into March)
1000 for $6.69. I will update when I get them and try on the thin grips.

Thanks for the link, Todd.

I just placed an order simply based on the looks of the ones you posted. The original ones I ordered had a 30% scrap rate due to off centered holes & ruff edges, but for the price it was OK.

Cracked Grip Panels; I do remember Burgs had some split on him, but I don't know what size O-Ring he was using. If the counter-bore in the grip panels is close or shallow, then it'd be best to use a 3mm I.D. x 1mm Thick O-Ring - I actually tried those but settled on the fiber washer due to its thinner, .5mm thickness.

Out of curiousity, what's the advantage of using o-rings or fiber washers on grip screws?

Thanks,

Mostly to stop the grips screws from loosening and backing out and having the grips then shift or move.
I still have plenty of both types of "O" rings, so my offer to share still stands to HPC members. If you want some, just DM me with your address.
