You can’t go wrong with a Berretta 92 fs. I’ve had one for about 4 years now and as of now I haven’t had an issue. It is not fussy about any brand ammo.
Take a look at Athlon Optics. I have one and feel you get a lot of scope for the price. Several places sell them online. All for the same price. As far as MOA, use this if you see things in feet and yards. Use MRAD if you see things in meters (metric system)
