My Browning High Power. It was my first gun and will never get rid of it, and I can shoot it the best out of all my guns + common caliber, Glock 19 would be my 2nd choice. Steyr Scout in .308- Simple to operate, common caliber, durable, I already own it. 2nd choice- Ruger 10/22
Glock M32. This is the mid-size model similar to the M19. It allows you to shoot either .357 Sig or with quick change of barrels .40 and 9mm and with a quick change of the top end and magazines .22 long rifle.
Glock 26 for handgun, but I'm not sure about the longarm. If I were going for asthetics and fun, probably M1 Carbine, or Garand. AK for defense I suppose.
Assuming that personal defense is the primary issue, I would choose a piston AR (probably Ruger or LWRC, or maybe a gun with an Adams Arms upper). I would pick an AR not because it is the most reliable or durable, as I don't think it is (IMO) , but because there are so many out there and so many spare parts and so many people that work on them. I would choose a well designed piston gun because I believe that a piston gun if properly designed with high quality components is more reliable, less maintenance intensive and more durable than a DI gun. I would make sure that I had some spare parts for the piston system, all other parts are interchangeable with any AR if you pick the right piston system. 5.56 ammo should be the among the easiest to find given that the miltary and LE use it. I think an AK (7.62x39) is more reliable and durable. It would be a close second choice. For a handgun, it would have to be a Glock 17. It is among the most reliable and durable handguns as well as there being so many out there. They are also very simple to work on. 9mm should also be one of the easiest handgun cartridges to find again because it is so widely used including military and LE.
Glock 23. It is compact enough for concealment, ammo is available everywhere in the US, and it is reliable. I also carry my 27, in lieu of the 23, but sometimes both.
I'd pick an AR-15 and a 1911 .45. In addition to being great self-defense weapons, they are a lot of fun to shoot.
Sig of some type for the pistol as they don't use a composite frame and either a rem700 or ar for the ease to find replacement parts. The handgun covers self defense/short range now what you need it long range.
Beretta M9 for reliability, availability of spare parts and the NATO 9mm chambering. Toss up between Rem870 for stopping power and versatility for hunting birds to big game, but heavy ammo or the ever versatile 10/22 for quiet, lightweight, accurate rifle.
Pistol: HK P30 V2 9mm. It is an extremely simple pistol: no hammer release or safety. Just a DA trigger with a long clean pull. Long gun: m4 clone +Trijicon 3x ACOG I suppose I would want a shotgun for home defense if I owned a home, but I feel pretty comfortable with my pistol for home defense. In fact, if I could only choose one weapon, I would pick the P30. If I hunted or relied on a gun for food though I would pick a rifle.
me i´d choose a Mossberg m500 and a Ruger P-85 9mm had a mossberg as a work gun for a year... nearly felt sorry for how it was treated... but it never failed me. /Roger
Glock G34 w/ 33 round magazine & a M4gery with a Trijicon Acog 4x32 and Surefire M900 series weaponlight.
