Bad Thompson Buffers


Recommended Posts

I've had the same thing happen with some old M1911 buffers. They must have a fairly short shelf life, but had likely been in my spare parts for 20+ years. I have no idea where I got them, back in the day...

Sorry no picture, my antique flip phone stopped sending photos years ago. The ones I got from him are a black neoprene/urethane(?). I got a couple years ago from him and they are still look new running thousands of rounds, one in a friend's rental 1928.

the yellow translucent plastic buffers are polyurethane (synthetic resin)

 

the black rubber buffers are neoprene (synthetic rubber)

 

the original red buffers are the original commercial synthetic plastic called bakelite (phenolic resin).

 

 

The polyurethane and neoprene are a LOT softer than the bakelite

 

The polyurethane is probably the best of the three.

 

 

We need to see if the buffer ever gets hit by the bolt.

 

Maybe put some scotch tape on the gun at the end of the actuator slot an see how far back the actuator comes.

 

Just keep moving the tape until it just barely clears the actuator travel.

I just emailed PK and he dropped them in a envelope and mailed them. ( need to send payment of course) . Then be done with it. 5, 10 bucks or something, can't remember.
