Is there any difference between a mod. 19 - 6 and a 19 - 4. Which one would be older? Thanks.


Ben.

Ben, the M19-4 will be pinned and recessed and will be the older model.

Hey here are the dash differences...

19 (1957): Stamping of model number.
19-1 (1959): Change extractor rod, right to left-hand thread.
19-2 (1961): Cylinder stop changed, delete triggerguard screw. (1963): Introduce 6" barrel.
(1963): 50 manufactured with 2.5" barrel, serial range K544672–K544721.
(1966): Introduce 2.5" barrel as standard.

19-3 (1967): Relocation of rear sight leaf screw. (1968): Delete diamond-insert grip.

19-4 (1977): Change gas ring from yoke to cylinder. (Not really an "improvement". It did make it slightly easier to clean if there was heavy leading, but basically was a cost-cutting measure.)
19-5 (1982): Eliminate cylinder counterbore.
19-6 (1988): New yoke retention system/ radius stud package/floating hand/ hammer nose bushing
19-7 (1994): Change to Uncle Mikes combat synthetic grips, drill and tap frame, change extractor, change rear sight leaf

Thank you gentlemen.

Ben

The very last -4s were unpinned, unrecessed or both.
