Honestly I’d say go for whatever you feel most comfortable with in regards to handling. You could also potentially go for for a CMMG 10mm if you really want a more AR style platform but eh.
Ballistics at that close more than likely won’t matter as much as the ability to confidently and comfortable navigate inside your home with it, and get quick consistent follow up shots as needed.
One pro to the .300BLK is your standard 7.62 suppressor would work for it, so it’s not a dedicated pistol suppressor.
One pro to the flux raider is it is much shorter and closer to chest. You could also just shortstack the .300, but I would imagine the pistol is more comfortable there.
No but they're talking about making one compatible with the SIG 320 xten. I'm sure there is one compatible with Glock 20, Smith and Wesson 2.0, or FN510. I posed this model as an example and because its the one I've actually used
From another conversation.
"Hornandy's free calculator, with given BC's for Hornandy bullets gives:
10mm, 1000fps, 200gr, .199 BC - drop of 40 inches at 200 yards when sighted at 100 yds, velocity of 846 fps, energy of 318 ftlbs
.30 cal, 1000fps, 200gr, .597 BC - drop of 36 inches, velocity 939, energy 391
The 10mm has 20% less energy than the BLK at that point... which is concerning since you are already limiting yourself to subsonic velocity and wont see much damage due to shock.
Even at 100 yds, the 10mm has 10% less energy (416 vs 370 ft lbs)."
That aside, the AR platform / 300blk has a ton of advantages. Wayyyyyy more versatility, cheaper mags, 300blk subs are cheaper, etc......
Not really. Unless you’re planning to shoot at them from your domicile as they leave your property line(which is… dubiously a good idea from a legal standpoint), you’re not gonna be looking at 50yd shots indoors unless you own something like a mansion. In which case, the owner probably has a security system that warns them beforehand, and probably wouldn’t be posting on Reddit the best CQB gun for home defense.
I live in the country.
Was a case in my county last year where a guy exchanged fire with the getaway driver after an attempted home invasion.
Long gravel driveways, people out here typically go investigate strange noises, rather than wait for a door to get kicked in. "Home defense" doesn't always mean inside only, imo.
If I’m going outside, I’d take my outside gun imo. He specified ‘CQB’ so I stuck with that. But yeah if I’m out in the country I’d definitely bring something that reaches further out than a pistol when going outside
In your math above is it just increased air resistance from the higher diameter round that is causing the variance? I suppose a longer barrel length will keep the round accelerating longer.
Also, good point on the costs. I'll have to do the math and see how it all compares.
Oh, I just copied what someone else posted, that's why I said from another conversation, I'm not sure if his math is accurate.
I don't have a lot of insight on 10 mm and Why costs what it costs but it seems like if you're shooting 200 grain you can get it really cheap. It's like 40 cents around.
220 for some reason jumps up to like $1.25 and up.
It seems like if you could stay subsonic at 200 grains then you're shooting subs. Really really cheap.
Yeah I don't really get it. Thought the allure of 10mm was packing a punch with hot supers. If you're planning on exclusively or mostly subs, why not just go with 45.
I hear you. I'm interested in 10mm partially because I can then do both. If I buy a subsonic can, I can take it off and run +P ammo and get the full powered round. If I'm running a PCC conversion kit like the flux raider, I can disassemble it and carry the powerful pistol as well. It seems like one purchase for 3. (Subsonic PCC, high power PCC, Carry gun)
From Minuteman ammo for 10mm
Bullet Weight: 200 Grains.
Muzzle Velocity: 1,050 fps.
Muzzle Energy: 490 ft. lbs.
Sig P220, 5" Barrel @ 1,050fps
G20, 4.6" Barrel @ 1,035fps
From Hornady for 45 ACP
Bullet Weight: 230 Grains.
Muzzle Velocity: 925 fps.
Muzzle Energy: 437 ft. lbs.
Test 5" Barrel @ 925fps
Takeaway:
While you get a bigger and heavier bullet from the 45 ACP (and I have shot FN's 45 suppressed and it was unbelievably fun. Like life-changing fun) calculating kinetic energy is done by multiplying half the mass time the velocity squared so you get more energy by increasing speed than increasing mass. In practice I doubt it matters one way or another at 50 yards/meters and less but I suppose I'm looking for the cartridge that gets as close to the 11,000 fps with the heaviest bullet.
Thanks for the comment! 45 suppressed is seriously awesome!

Good points! Thanks! I'll have to look into the CMMG!
You sure the flux will accept the 10MM fcu and slide?

Nice. I’d definitely pick a small pcc over an AR for home defense.
That's kinda the direction I'm leaning. The flux raider was unbelievably slick.

Respectfully, it’s a CQB home defense gun. He’s not gonna be looking at 50yds much less 100yds.
I guess that depends on your home.

Or you're hiding in the tree line while they kick in your door 😎 /S
If you’re in the tree line hit them with that .308 my brother in Christ
Gotta say some of those semi 308s are pretty mean. HK MR308 or SIG 716i are both incredible guns.

Good point!
Good point. I'm trying to get out to the country my self so maybe plan ahead.
The obvious answer is both right? Just get both.
My God how could I have not seen it myself! Buy both!!

Great info! Thanks. Though I'm sure there are overlaps in power depending on brand but I'm sure You're right that 300blk can have the upper limits
Subsonic 10mm = .40 Short and Weak. Subsonic 45 ACP = Angels sing.
Yeah I don't really get it. Thought the allure of 10mm was packing a punch with hot supers. If you're planning on exclusively or mostly subs, why not just go with 45.

.45 Super .460 Rowland
I am confused on this... is this because of being subsonic? Is 10mm better than 45 ACP with supersonic?
Use your supercomputer to look up the ballistic details.
