Beretta 390 st value

[scout800]

I have a chance to pick up a beretta 390 st for about $675 in pretty good shape, I was wondering if this was a good price and what differences there is between it and the 391 series.

Thanks

That sounds like a good price but it's hard to know without seeing the gun.

The 390 uses a different gas handling system and more of the mechanism is in the forearm compared to the 391. Because of this it has a wider forearm and barrels from earlier Berettas autos will interchange.

The 390 also has an all steel trigger assembly versus the composite on the 391 and is a little easier to disassemble for cleaning.
