Go for your life guys, I'm not trying to start a shit fight, but just laughing at what you are trying to use. go to any good gunsmith and ask them that you want to use dentist amalgam (goo) or better still ask him to do it for you and see what his reply is. Seriously guy's it's so silly it's laughable. I do get the gist Daryl, if only you read my original reply,

"If it does not affect shooting etc then there really is no need to mess with it"

In the very first line of the this post the original poster said:

"Warning, this is a silly idea of mine so please feel free to call me a dangerous nutter."

Well I'm calling it guys.

Sure there are possibly other ways to do I'm just having a laugh at the original idea. I don't know why you are so defensive. I'm just having a laugh. Take a pill sit back and relax.
