I don't have any experince wiyh the 720 but, I do with the 620. They are the same gun with a different receiver shape. They are well made guns with a lot of features like stock shims and an automatic magazine cutoff. The 620/720 feels and balances very similar to the Beretta AL391 in 20 gauge. They are very light, thin, and have a small feel to them. This design is very easy to clean and even easier than some non gas operated auto's.
