I have a 327 Nightguard sitting beside me- basically the scandium aluminum version of your 627 but with fluted cyliders. I want an 8 shot stainless or blued 627 with fluted cylinders and a 3” barrel. very hard to find.
I came very close to getting the 327 scandium 21oz snubbie. I had a 7 round titanium snubbie that was too ammo sensitive. I’ll bet yours is a real thrill to light off.
