Folks,
No disrespect to anyone here or anyone doing testing shared on Internet.
Here is the deal, one has to Investigate & Verify their guns, loads with the environment they will be in.
There were no gun schools back in the day, the only training one received being a LEO, or in the Military.
No 911, No Internet, and even back in 50's, 60's and since, folks have parroted what they themselves have not actually investigated and verified.
The Reality is, there is no Absolutes.
I have worked in the main OR, and seen the fellow live, that stuck a .357 medium frame revolver, with .357 loads in his mouth, and trip trigger - live.
Ditto for those shot with 00 buck, and 12 ga slugs.
Contrast not long ago, using a '29 model Colt DS and Older Model 36 snub nose revolver, with standard pressure, 158 gr, LRN (yeah those called Widow Makers) one shot and Cow down right there.
Just a lowly 38spl.
Investigate & Verify.
We built replicas of actual home, apt, and business settings, as construction differs from just the materials and how they react to projectiles.
See, we beefed up walls, back stops with furniture, cover, shooting lanes and the like with materials we actually shot.
i.e. 12 or 20 ga slugs for Condo use.
Oh that person had that condo, secure, and the shooting lanes , cover, and backstops , would stop a slug, some would stop a 30-06, because we shot '06 at these.
We used one way mirrors, glass bricks, special bullet resistant glass...
In a serious situation, we HAD to know we could shoot through that mirror, or glass French Door and understand projectile deflection , get shot placement, and know that backstop would indeed stop.
We had cover, so if the criminals shot back, we had materials that would stop up to 30-06 even 12 ga Brenneke type slugs.
Heck some of the business guns were/ are Model 70 in '06, and Lever Action in 30-30.
One setting is using a Bounty Hunter with one barrel 45-70 and the other 12 ga slug.
Not a game, instead a very serious, real deal how it plays out in the Real World for some folks and situations.
One popular reduced recoil loading I/we dislike, it has a "rubber ball" and that ball will bounce back and hurt, not to mention distract, someone shooting that load.
It might surprise some, how other loadings richochet, and can cause injury , and distraction to a shooter defending in a serious situation.
Hence the reason we use cover, not only for those defending, also employees, or other family members.
A showcase, with storage underneath, has bullet resistant materials, tested, at point blank range, with '06 and 12 ga Brenneke.
You shoot a BG in the process of armed robbery and his/ her finger trips trigger on a firearm as they go down and that bullet goes down into a showcase where a employee dove down for concealment, or cover, and they still get hurt or dead.
Same deal in a residence.
Practiced plans with family, with the smallest and youngest kept in mind.
It might be a codeword yelled out, as the adults cannot get to a kid, and that kid gets down and behind a "toy box" that is not a toy box in his/her room, instead has media to stop bullets and pellets.
Book shelves, lamp tables with covered doors for storage underneath, Headboards of a bed with media b/t headboard and wall, dresser drawer, with medial behind it...
Here is a real set, for an apartment, a lady uses.
Her apartment has one of the firewalls on one side, she chose that apartment because of location, and that firewall played a part in our decision.
Open door, and one steps into living room.
Straight ahead is the one bedroom.
To the right, just before one enters bedroom, is a kitchen bar, then continue into kitchen.
Standing in the doorway immediate to left, is a Entertainment center with the doors that cover TV, and below the doors cover Stereo, DVD, and everything else.
The back of that Entertainment center, has had added two, 1/4 Steel plates, that are concealed with matching wood, stained to match center.
These are removable, for ease in moving.
Wall opposite, that behind is bedroom, still in LR has a small sofa.
Behind it are glass bricks about a foot think, and these come up and make a behind the sofa "knick-knack" shelf.
Enter Bedroom and the nice long dresser, has the steel plates like the entertainment center.
Back at the front door, and at the small bar, are again glass bricks about 6" thick, these are on both sides, where one sits at that bar , both LR and Kitchen side.
Between front door and that bar, is the "guest closet" and there is a pc of drywall covering a sandwich of 1/8", plexiglas, and 1/4" steel.
Jackets and whatever cover this, and the idea is, if someone is at front door,or shoots into LR window at that angle into Kitchen those items, plus HVAC unit which is in Kitchen will offer cover.
Just part of what we did, not all, still she knows those steps will stop various projectiles, as we actually shot the darn things before these were implemented.
Her CCW, her bedroom gun, and other defense guns, will not penetrate these things.
She advertises nothing.
One will never know she knows anything about guns, or has even shot one.
She does not use a Residential Security Container (AKA Gun Safe), what she does have, is a Real Safe, that is TR/TL rated and small and one might say "custom" as it was bought used , and it was originally made and used by a Gold Dealer.
It does not look like a "normal safe" and it is truly concealed and secured professionally in that apt.
The rest of her valuables are in a Tann Safe, rated TR/TL 60 and it is inside one of 4 Walk in Vaults off site somewhere.
This gal is in her mid 20's, and has been shooting since she was age 4.
She shot her first 100 straight in skeet at age 14, she run the 50 yard police quals at age 15, with a ,357 revolver.
She has never been to a "known" gun school.
What she does have, one cannot get off Internet.
This is real deal stuff, and folks were doing before I was born in the mid 50's, and still do.
Investigate & Verify.
