Thanks for all the input!
Was out of town yesterday and visited an Academy Sports & Outdoors store they had there (limited on stores where I live, Academy is one we don't have in town) and they had some 9mm ammunition. I'm bad with remembering brand names, but these particular rounds had steel jackets with a copper covering and with a wax coating on top of that. I'm certainly, certainly no expert on firearms or ammo., but that sounds like something with TOO many features for just a bullet. Doing some quick figuring, I decided that since I hadn't heard of all those features for a simple bullet, the fact that they were four dollars cheaper for 50 rounds than anything else I had seen, and that the shelf was fully stocked with them, but out of stock on a lot of other stuff, I decided to stay away. lol The casings were kind of a weird, dark green sort of color.
I really do appreciate all the responses. It sounds like the Ruger SR9 is quite the pistol. I got it as a birthday gift and have only shot 50 rounds through it for SDA class, but from all the reviews online and comments of a couple strangers in SDA class, and the way it handled while shooting, I think it's a gun that's going to last a long time. I'm going to get a booklet of some sort to keep track of what I've shot through it, when, where, and how many rounds. I also got a Hoppe's No. 9 gun cleaning kit as a gift with the gun and I used it on the pistol as soon as I got home with it.
Another ammo. question... As I was reading some reviews on different kinds of ammo., I saw some reviews about people that buy ammo. by the case or even by the pallet. Where is it one can purchase, say, a thousand rounds at one time? I don't imagine anything potentially explosive can be shipped via USPS or FedEx. lol
Also, my dad has a concern that ammo. ages. I can see a hundred year old round being not as good as a fresh one, but is there really a shelf life, I reckon it can be called, for ammo.? Are there better ways than others to store ammo.?
Thanks everybody and sorry for all the newb. questions!
