Honestly, one all purpose rifle, the 7.62x39 and the VZ58 in particular is a great multipurpose option for all needs w/in 300yards/m -- better than AR15 for all needs w/in 200y/m IMO. But both are overkill for an
indoors-specific home defense weapon/caliber. You only need a rifle indoors if you're needing to penetrate body armor, which as a civilian, you don't, or shouldn't.
EDIT: Should add, though the VZ58 is a military surplus weapon from the 1950s, it's bones are the where Western/Nato models are finally ending up. The weapon was ahead of it's time, and with some of the modern upgrades, you have the same ergos and similar action to the modern SCARs, etc short stroke piston weapons, w/o all the polymer. And don't forget the tab if you're entrusting your life to the weapon.
For a home defense specific weapon, our primary is the Keltec Sub2000 in 9mm w/ the Glock Mag setup (33 round OEM glock mags -- though the Sub2k have been recently made of unobtanium, the pricepoint here is cost on GB [only place I've seen them without a months long waitlist] of $450-500 plus ~$100 in essential mods [waitlist you'd end up at that the $450 to $500 total pricepoint I'd imagine, a $100 GB premium]; cheaper than the VZ58/2008 when all said and done, considering rail costs, etc). The primary whys here are:
-sufficient but not overpowered/overpenetration within 50 yards (357 magnum equivalent at point blank range),
-excellent and cost effective performance in soft targets (read: human flesh, if defensive loads perform at standard velocities they're even more devastating/better at expanding/fragmenting at higher velocities which mitigates much of the potential for add'l penetration) at price points at less than 33 cents per round (primarily using Federal 9BP -- and you're looking at 50+ cents/round for similarly performing 7.62x39 rounds),
-muzzle blast and flash less than pistol of same caliber, just a little above 22lr out of a rifle actually (this allows for no disorientation/distraction as well as fast followup),
-a more ergonomic and accurate platform, especially for non-experts/beginners/those who don't have hours of range time under their belt; all rifles are better than pistols in this regard (I also think that a pump action semi-auto shotgun is the most difficult platform for novices to master, especially with issues like short stroking, tactical reloads, getting back on target with substantial muzzle blast/flash/muzzle rise, etc),
-the sub2000 empty and unloaded weighs 4lbs versus ~7lbs VZ2008
-at 29.5" open, it's essentially shorter than pistol is with arms extended and locked (VZ2008 is 34-35" open and my arms are 34-35" in dress shirts),
-it's also friendly for mounting a light/red dot/laser/etc -- I have a fiber optic sight and flashlight only on mine,
-it's easy to mount a light that actually points where you're looking, pistol maneuvers with lights are more complex IMO even if mounted due to weapon retention precautions,
-you can mount a sling which is a major plus for weapon retention,
-and ultimately, it's a weapon that both me and the Mrs are comfortable with and confident using.
Sidearms/pistols as secondaries.
Basically, the only thing the VZ58 and Keltec rifles lack that my pistol has is tritium sights. All HD weapons should have them IMO, but with a mounted light, they're less important...
My current preferences of weapons with rough uses for the personal defense/basic initial personal collection that covers all the bases setups if your curious (this is a value proposition list btw -- the best bang for buck; quality/capability first with cost the secondary consideration -- I approach weapons as such and as a cost-conscious new gun owner you will too; BOTTOM LINES are that trained well on with one weapon is worth 10 in the safe, at least 10 magazines per self defense weapon and 6 for your fun guns, you can never have enough ammo (but a couple thousand rounds/a couple years of recreational needs should be a minimum goal to work towards), don't forget body armor that you'll put on before investigating bumps in the night [like training, body armor and one gun beats no body armor and 10, level 3a minimum, 3+ ideal], you can't and don't want to shoot what you can't see so don't forget weapons lights or a flashlight always at hand, and lastly make sure you have extra springs and critical other spare parts on hand for each self defense weapon you own):
Handgun: 9mms -- Sig 2022, CZ75, Canik 55 Stingray-C (I prefer DA/SA, but for striker the Canik 55 TP 9 and Glock are actually probably preferable and easier for brand new shooters -- stick w/ 9mm and good ammo and you're GTG)
Handgun: 22lr - Bersa 22lr (again, this is DA/SA weapon, for striker practice a Ruger Mark 3 is probably best)
Indoor Home Defense: Keltec Sub2000 9mm, Uzi Rifle or Suomi Rifle or Colt 9mm Carbine (Colt 9mm are blowback not DI actions, same action as Uzi and Keltec, not sure about Suomi) would also swap in here.
Carbine: VZ58 7.62x39 - primarily intended for outdoors w/in 200 yards, ideally w/in 150 yards; red dot optic
Rifle, 22lr: Can't go wrong with a Ruger 10/22 (especially their 50th anniversary edition, the edition rifle, not just every 10/22 with the sticker) or Marlin Model 60, in that order IMO.
Shotgun: Remington 770 for pump, and Yildiz for O/U sporting. Don't know crap about or have an autoloader...
--To this point is, generously, the max distance where any civilian in a situation that's not SHTF, WROL, etc, has a legitimate self defense use/need for the above weapon(s)/rolesRifle: Galil 5.56 Nato - intermediate round, intermediate range; ideally 150-300 yards, but 500 yard capable with standard 55-62gr ammo; 1-6x DMR Optic; ideally any piston-driven AR would swap in, but a direct-impingement AR by a reliable manufacturer is acceptable too... More effective at longer range with a 68-77 precision round.
Longer Range - K31 7.5 Swiss bolt action; 300-500 ideal, but 500-1000 yard capable; match grade ammo at bulk .308 costs. New production Remington 700, Winchester 60, or Savage in .308 (or if you want .270 or .30-06) are good alternatives.
