you picked the worst possible time to buy a rifle and pistol, or any gun really. There is no other point in history where you would be in a worse position.
What are you going to do about ammo? You don't have any, and 5.56 is still $1.00 per round and shitty ass 9mm is still .80 cents per round. To put that into perspective, I was reloading 300 win mag for $0.40 cents per round with bthp match grade bullets before the panic. You are going to get totally ass raped on ammo right now.
Don't even waste your money on a rifle right now and the ammo. Forget about it. If they are banned, oh well, but even if they are banned it still would not be worth the cost. Under no scenario should you be spending $700 for a PSA "freedom rifle." You should never be spending anywhere close to $1,000 on a factory PSA gun. If it is worth $1,000 after you modify it with aftermarket parts, ok, but from PSA that is ridiculous. People need to start having standards around here. Paying anything to "have a rifle" and dumping $1.00 on 5.56 is retarded and counter productive. People that dumb should not even be allowed to own guns. Just forget about a rifle right now until the market corrects itself.
If you want a .45 handgun, get one of the polymer ones. Glock has the most aftermarket support. I personally hate Glock but clowns love it and they do work all right. Not much besides that now that everything is geared towards the hyper weak, hyper homosexual 9mm. Never buy 9mm, it is an utterly worthless caliber. I don't know of any other major 45 guns in production these days. Springfield has all but abandoned the XD. Sig Sauer never really supported 45 much with the p320. You may want to try to get a Sig Sauer p220 if you don't want to go the Glock route. The p220 and Glocks are both easy to disassemble.
but yeah, in summary, forget about a rifle right now. Get a p220 or a Glock. Frankly the p220 is the better gun but you will pay more. With guns, let me tell you that it is always worth paying more for a better product.
