Thanks for the details. You have bought some guns I share an interest in.
The Ruger .380 - is that the LC380 (one I have thought about for a while, now), or the LCP (I or II ?) - which I have experience with (both the I and the II), and like.
The M&P 9mm Shield - I like that gun, too. And from what I have heard, it is extremely popular (no wonder why!).
The SD9VE - I have heard good things about that one, though have never shot it. How do you like it so far? Seems like it would make a good carry gun with the right holster. Have you tried carrying it, yet? How did that work out?
As for shotguns - I have experience mostly with the tactical shotguns (18+ inch barrels, mostly). Depending on your tastes and needs, you can do well with several different models. Currently, the one I shoot the most is the Remington 870 Express Youth in 20 gauge. It is a little shorter than the regular (adult) sized shotguns - making it little easier to use for home defense. But, I use it for sporting clay shooting, too, and it works well for that, too.
Although, I do have some experience with various rifles, depending on what purpose(s) you have for a rifle, there will be people here that know a LOT more than me about them. Still, please let me/us know what you are looking for in a rifle(s), and I am sure lots of suggestions will follow.
Also, for each gun, some kind of price range you are looking at will help. And especially for rifles, will you be adding a scope or other accessories?
