marc_cesa Posted August 23, 2004 Share Posted August 23, 2004 i shoot a gold cup trophy. had about 2000 rounds fired from it. My problem is that i have already replaced the stock plunger tube because it came loose after 500 rounds and i replaced it with an ed brown. The ed brown plunger tube is loose again. Want to know if anybody has any idea about my problem before i go to a gunsmith. Right now, i just sanded the inside of the left grip so that the notch at the top of the grip pushes on the plunger tube and keeps it from moving. The plunger tube gets loose every time i engage the thumb safety. But havent had any malfunction yet while firing. Link to comment Share on other sites More sharing options...
Kingman Posted August 23, 2004 Share Posted August 23, 2004 Brownells sells a tool for staking the tubes in place. I have sometimes found it necesary to really beat them into place. Link to comment Share on other sites More sharing options...
.40AET Posted August 23, 2004 Share Posted August 23, 2004 But havent had any malfunction yet while firing. Get it fixed quick. If the spring works its way out, usually at the LAMR, you won't be able to put the safety on...No safety, no shooty. Link to comment Share on other sites More sharing options...
bompa Posted August 27, 2004 Share Posted August 27, 2004 Have you checked to see if the thumb safety is making contact with the plunger tube ?? I am sure that the safety hitting the tube would cause it to come unstaked.. When restaking the tube a bit of red lok-tite under it will help also..

mcoliver Posted August 28, 2004 Share Posted August 28, 2004 Any problems if the plunger tube gets fixed (silver soldered or something) for good? Link to comment Share on other sites More sharing options...
ChuckS Posted August 28, 2004 Share Posted August 28, 2004 I had a plunger tube come loose on a SA single stack. My smith was able to re-stake it. I turns out, in these modern days of saving money in production, the inside end of the plunger tube mounting holes holes have minimal / no bevel to allow the plunger tube pins to squish out into when swaged. So the only force holding the tube is the compression in the straight walled hole and not the "cone shape" that would form on the end of the pins if the hole had the proper bevel. Take the gun to your 'smith and have him re-stake it. Link to comment Share on other sites More sharing options...
