1377 Valve Interchangeable?

[benji397]

Hi All,
I have a 1377 Phase II pistol from 7/91, actually it's a bag of parts, and would like to put the valve in my 2010 Phase III pistol to replace the aluminum valve. Will they interchange?  Thanks

Yes.  1377 valves haven't changed over the years.  One fits all.  Your older one may need some TLC to bring it up to todays standards.  Mainly, cleaning & then see how it seals.  May need a new valve stem.
Good project......
