How do you reduce the clacking noise while pumping up your guns ?

[tri-5-ron]

Hey all, (Same post/thread made on the GTA)

Just wondering how you guys quiet down the annoying "whack whack" sound while pumping up your 1377 / 1322 / 2289 guns ?

I've been using my newly built carbine to do some late night ratting in the back yard. Pumping it at midnight or 1:00am is not very neighbor friendly.   
I seem to remember someone (I think maybe it was Tater) saying to use a strip of felt or something ?
If that is your favorite method/material,.. are you putting it inside the pump handle ? OR , Are you sticking it to the bottom of the pump tube ?
Are you guys using any other methods/materials ?

I was wondering about maybe using some RTV Silicone Sealant to fill in some of the hollow areas of the pump handle.
(sort of the same idea as stuffing foam rubber or squirting expanding foam into hollow rifle stocks)
Hopefully this could to help eliminate the "amplifying effect" that the big fat plastic 2289 handle seems to produce / contribute.
  I realize that the noise is also there with the original pump handles too,... it just seems even louder with the back packer handle.

So tell me what you guys have tried, to reduce the pumping noise.
Various materials ?
Positioning and placement ?
Pics ?

Thanks in advance for any replies !

There's some ideas here:

I use 1/8" thick F26 gray felt with the adhesive backing....cut them 3/4" x 3-1/2"
You don't need the adhesive backing though...rubber cement or something similar would work
You can see it installed in this pic:

i use controlled pumping. i slowly pump my gun when i get to the closing of the pump arm using a little more muscle i gently close the arm. though it is not totally silent its not even half as loud as just letting it slam shut. i imagine if i had something there it would be perdy darn close to silent. i think i'll try something there and find out

I just keep my thumb between the pump arm and the tube.
Hurts a bit, but it stops the noise.

I use a piece of heater hose.  Fits perfect in the handle no glue no fuss.  Hardest pate was splitting the hose and getting the right size piece. When you drive a piece of junk you have plenty of little pieces of hose laying around

I use some felt dots similar to these:  http://www.homedepot.com/p/Shepherd-1-in-Heavy-Duty-Self-Adhesive-Felt-Pads-16-Pack-9952H/100372174#.Uk7rL1OLNvw    I also use Ed's controlled pumping method and slow down a lot right before the arm is closed.

Felt dots work well.

You can't even hear mine! Silent as a church mouse. Why? Because I shoot my co2's and leave the pumpers in the house 


Sorry, could not resist. I've had luck with Velcro strips in the past.
