Thanks to you both for your responses, especially to Kingruv for taking the time to type all of that. Some was known, some was not. So thanks!
Your opinion of Militec-1 is intriguing! Actually, had not thought of that before so that is a definite path to try.
My husband is now a machinist, but not a gunsmith, in this case we will probably seek out the advice/services of a professional gunsmith.
Very informative post! Thanks!
