There's nothing quite like getting a brand new gun. I just came back from my gun shop, I've got a new Remington 870 Express (with a 3" chamber) with two barrels (a 20" with rifle sights and a 28" with vented rib). The finish is fine, a bit spartan looking but decent. I might work on the wood parts to make them nicer. I can't complain since I got the shotgun, two boxes of Winchester Super X shells (00 Buckshot and slugs) and a Hoppe's cleaning kit in exchange for my broken Taurus Judge. I'm dying to try it out, since it's my first shotty (I've used them before, but never owned one). But I've got to wait until tomorrow. I've got it right next to me under my desk at work, and I'm fighting the urge to start playing with it. Luckily, gun fondling is allowed, almost encouraged, in this office, but the hippie interns might be scared. Anyway, I'm planning on shooting it a lot before doing any mods other than an extended magazine. Is this a good idea or is there anything that absolutely must be replaced? I'm going to focus on defense use at first, hunting and other stuff can wait (I mean, if I miss a shot hunting, it's no big deal, can't say the same about a HD scenario). I'm planning on keeping it loaded with a mixture of slugs and 00 buckshot. Is this a terrible idea? Overpenetration is not an issue at my house, I'm just worried about feeding realiability with different types of ammo. After I play around with it a bit tomorrow, I'm signing up for some defensive shotgun classes.
