The Beretta was/is offered with either single or double trigger systems.
The Winchester grand euro was to the best of my knowledge only available with single trigger of the inertia type.
The Grand European single trigger is very reliable as is the ejector system.
These Winnies were first available in the early 80's and were pretty well finished by the middle 80's.
Most, but not all, came with factory fitted EAW QD scope rings.
I've seen them for sale in 257 Roberts, 270 Win, 7x57 R, 7x65 R, 30-06 and 9.3x74 R.
Once regulated they are a great small cal double rifle and I have used one on lots of Australian medium and small game over quite a few years in 7x65 R.
I regulated it to shoot the 160 gn Woodleigh.

The Beretta would be your best bet though so long as it has the factory scope mounts.
The Beretta o/u rifles that I've handled all had a very narrow top rib of about 1/4 inch and this is not really wide enough to allow a solid installation of common type QD bases.
The factory claw bases are a saddle type which are fully supported by the top of the upper barrel surface and this is the best method for guns with small or narrow top rib IMO.
If you bought a Beretta with no scope mounts, and then had to get claw mounts fitted, it would cost a LOT of money compared to the overall cost/value of the firearm.
