I have a chance to buy a slightly used 3901 for my son. I have read several post about this gun and all were positive. I have an A303 and I have been using it for 16 years and love the Berettas. Any new info on the 3901 y'all can give me?

It is the current version on the 390, which in turn was developed from the 303 action . . . adding a secondary gas vent to make it compensating.

The 303 is still my favorite Beretta action, based on its simplicity. However, I have several 390's currently and also a 391 which have proved to be fine semi-autos.

It is the current version on the 390.

Unlike the 390, it only comes with a rounded receiver. The 390's were mostly angled but, some were rounded. The 3901 also does not have the bolt lock lever on the left side of the receiver.
