The Beretta is a nice little carbine. Very fun to shoot with decent accuracy and great ergonomics.
The best 9mm will always be the MP-5 for me. Absolute perfection and I really wish they were a less expensive option. Fun, fun, fun, and did I mention how much fun those are to shoot?
I bought my MP5A3 back in 1992.Put about 125K rounds through it since then.Had to rebarrel one time,other than that,no issues.Bought a suppressor the next year,nice combo when you don’t want to make a lot of noise.
