I'm starting to wonder if I can have a .38 Superb (damn good turn of the phrase) barrel fit to my 9mm Defender. I just wonder if the juice is worth the squeeze with a 3" barrel...
I will have to defer to the actual gunsmith, @Joe C. I know just enough to be dangerous.@ThePlumber or @Joe C may want to help us out here. Any suggestions would be awesome!
I believe many makers use the same breech face dimensions for
9mm, 38 Superb and 40s&w therefore the main consideration is getting the correct extractor and ejector tuned to function with the simi-rimmed case of the
38 Superb. Dan Wesson however claims their 38 super and 9mm breechface is cut specifically fit each specific case. The real trick is to have the extractor and ejector tuned so the gun feeds and ejects with both rounds reliably.
In my case this is not so critical due to the fact that I load my 38 Superb using
Starline 38 Super Comp cases. This removes problems with the Semi rimmed
38 Superb cases. My task is getting these two guns to function with factory ammo
As well as my 38 Super Comp loads without losing 9mm reliability.
The Valkyrie is a Commander 4.25” gun.
I have no clue how the 38 Superb
will function in or what the ballistics will be out of a 3” barrel.
