I started buying air guns to prepare for shooting some classic firearms I have wanted to mess with. Long story short, I really became captivated with the air gun platform and have acquired roughly 20 of them....I saw this thread and have also been thinking a lot about this topic because I find it interesting. I felt compelled to drop my two cents into the pot.
I am no firearms expert....there can be no argument against packing a Glock or 1911 chambered in .45 acp...no argument. It will work and it will handle an intruder problem effectively and reliably....that said, as an engineer, I find it interesting to design things and to make a solution out of something that may not seem to work. I have developed a home defense scenario using air guns and I do think it would be quite effective....for what it's worth, this is my plan.
Weapons....
Beretta cx4 .177, 5 30 round preloaded clips...88 gram, 150 shots
Hatsan Torpedo 155, .25, 1 shot
Webley Patriot, .25, 1 shot
Gamo PT-85 holstered right
Beretta PX4 holstered left
Equipment...
Custom Kevlar tactical vest
Preparation is key....and I do not recommend this is the best home defense plan, but I do submit that whomever is foolish enough to see the NRA sticker on our front door, hear the dual ameirican bulldogs announcing their readiness...and still enter....I will prevail with that arsenal of weapons.
Basically, the vest is already packing the co2 pistols and all loaded clips, the cx4 is charged (I've tested the shelf time here) and each co2 pistol requires a simple 1 twist to charge. I'm up, vest on, weapons systems ready and I'm coming at the intruder with 200 shots of 8 grain 600 fps....30 plugs at a time....you would be surprised at how hard that thing hits....I have no doubt that it will exact severe damage to a perp especially with 200 rounds....once the beretta clips are expended, the rifles come off the back vest custom holds and there are 2 more shots at .25. Again, you would be quite surprised at the power those rifles have and how hard they hit....one well landed patriot .25 round would be quite damaging....once the rifles are chucked, should I have to get I there for some close wet work, the pistols are there. Again, these are not 70s daisy BB guns....these things pack more of a punch then you might imagine.
Again, I'm not recommending this to anyone as the best method of HSD, but I will tell you, without a doubt, I'm going to win the challenge and handily so. I doubt I would have to go past the cx4 and one rifle.
Anyway, just a fun little scenario I guess.
