Hi,
I have had a Rossi matched pair 22lr/12ga for a couple of years. I like it a lot. The trigger guard is plastic, and the wood finish isn't the best I've seen, but it is very solid and reliable. Mine is the older style - wood and blued metal, no safety and a less sculpted stock and foreend.
The 22lr barrel has fibre sights and is tapped for a scope. It is accurate, and the spent cartridge ejection is rather energetic. It is a very heavy, but well balanced barrel. It happily eats any 22lr, 22cb and rat shot I've given it.
The trigger isnt that good when you compare it to a lot of expensive rifles, but is fine when I compare it to the milsurp and bp muskets I own. They aren't designed to be opened up and have the mechanism played with, nor are there a good deal aftermarket bits for them.
As a 12ga it is very light and nothing makes me giggle more than shooting 3in slugs out of it. It points as well as can be expected for a non fitted shotgun and I have shot clays well enough using it.
It is inexpensive and a heap of fun. I only wish it was easy for me to get a centrefire barrel for it; say a .223rem. Being in Australia, it is very difficult. Apparently you can send it to Rossi to have another barrel fitted though!
I paid au$300 for mine, new in factory packaging. I would buy it again.
