Good deal for you Bret, I would say. I like the old .38's in any length or combination that Smith made them. The first one I ever shot was a old M-10 and I have liked them ever since. Good luck with yours.
I've had it out to the range for a quick try. It loved my hand loaded H+G wadcutters in front of 2.7 gr Bullseye. It didn't like the Remington factory stuff I tried after I ran out of my stuff. I had thought the cylinder thumb latch might cut my thumb knuckle in recoil, but no issue with the light loads. I have yet to try any "social" loads. Nice gun. I may change the grip as it's a bit short, making me hit the trigger with second joint of my finger. I have a set on my J frame kit gun that are just right and may try to find some like it.
I owned for a brief time the M-38 before buying a brand new 642. The M-38 was a delightful revolver. I wish I kept it around for handloads. I like the 4.2 grains of Unique under a 158 grain LSWCHP. It holds up good enough for "social work" should I chose to load it and displays reasonable accuracy out of the short barrel.
Great news and congradulations on your "new" M-38!
Congrats on the Model 38; mine has been a regular companion for many years. I like the Secret Service grips from Eagle. They do nothing to hinder concealability, yet make a big difference with recoil and look great.
