I've got KBVXXXX, 5/2014. No ridge on the top, 380 AUTO engraved on the top, BG 380 engraved on the side. From the above link, my barrel appears to be the forged.
The sad part is, the BG 380 has had it's share of issues without this coming up. Why manufacturers continue to make these changes to save very little is beyond me. MIM might be okay on these pistols, but I guarantee that everyone that reads these two threads will be checking their BG to see if their BG is one that got the MIM barrel. Just another thing for all to worry about, will this MIM barrel stand up to the test?
I had an early 90's Ford Bronco and had to replace the radiator twice, Ford's better idea, let's save money, go to plastic tanks and staple them to the core! Might have saved them little, but cost me in the long run!
And these companies wonder why we buy Hondas, BMWs, Lexus', Glocks, Berettas and Sigs (Sigs made where?).
