Beretta figured out how to take cost out of the 390 and 391 hence the A300 & A400. Still good guns and I've been a big fan of Beretta for many years but have started to look else where in the last few years. Anyone intimately familiar with the 390 and 391 should be able to tell the difference pretty quickly. Same with the SV10 Perennia. Cheapend version of the 680 series. I'd take a plain White Onyx over any other brand o/u under $3k. Can't say that about their new o/u's.
