I think the SWAT / special police units guys would field the best answers here, but I'll ask the hive as well.

Other than magazine capacity and a slightly longer barrel (7.78"), why would an FBI or special police unit
choose a SEMI-AUTO pistol caliber weapon weapon such as the H&K UMP (Semi-auto FBI Config) for
CQB instead of using hand guns.

It seems to me that if you're going to kick in a door then a pistol would be easier to wield in tight quarters.
What are your thought and opinions?

*****We're talking about semi-auto pistol caliber weapons only*****

I own a USC/UMP conversion and I would still use my USP pistol over my .45 ACP UMP
for home protection. With that said, I fully understand the different between a CQB assault
and home protection. This is a matter of personal choice for me and I don't kick in doors
for a living.

Sub guns are more accurate, controllable and have greater magazine capacity.



They're also harder to knock out of your hands or grab than a pistol.



Unless you're in a SUL position the overall size of someone with a pistol vs a sub gun is minimal, if not longer.

Magazine capacity is a huge factor, so it doesn't make sense to exclude it.



Also, the longer barrel means more velocity which usually means better ammo performance.



A subgun is held against the body when it's at the ready position, meaning better retention vs. a handgun which is held extended away from the body.

I would think that a subgun would be easier for someone to grab while you're rounding a corner and how
much more accuracy do you need in a confined space? I'm not saying your wrong. Once again, I've never

Given the situation, a sub-gun is still the better option, for a couple reasons;

Greater magazine capacity
Greater accuracy
Better retention
Better options for mounting of sights, lights and lasers

Hostage shot is much easier with a shouldered weapon.

You can grab the sub gun all you want, but a good slind makes it harder for someone to turn the gun on you. Think about that and then compare it to a handgun. Much easier to go after, cause a malfunction, and turn on the officer.

Think about how you fire your pistol. Extended arms, slightly bent. When you fire a sub gun your arms are tight to the body, pulling it into your shoulder pocket with a sling.



Both are easy to grab at but the sub gun is harder to take.



On the subject of accuracy if you look at videos of SF, SEALS, Delta shooting, they're all controlled pairs to the sternum and/or T zone. Much easier to be fast and accurate with a sub gun than a pistol.

Subgun gives you more leverage, more points of contact on the gun.  It's also generally going to be closer in to your body, easier to control.

Subgun.  Accuracy, mag capacity, recoil management, sighting systems, lights, and whatnot make a subgun a significantly more versatile platform...

Sight radius and steady three points of contact for the win

It depends.


Anything arms length and beyond, sub/gun or carbine.

Inside arms length and carbine will be difficult to impossible to handle, so pistol.

There is a reason the MP5s are all being traded in.

I already have a Colt M16 11.5" and Colt LE SBR with a LWRC 10.5" piston upper (not pictured). I've just always wanted a .45 cal subgun.

Longer sight radius, easier to retain, longer barrel gives you slightly better performance, easier to hang stuff off it.  Bigger magazines too.

There is a reason we carry a pistol as well.  It's good to have a secondary, and anything shoulder fired is not alwys the best choice for all situations.  If I was carrying a sub gun and a pistol, I wouldn't be uncomfortable at all running through a house with my pistol if my primary went down.  I just have to do some things differently.

It is far easier to lose control of or use of a pistol than it is a long arm.  Often in long arm retention scenarios I have been easily able to retain control of the long arm, and it is fairly easy to use one's own center of gravity to direct the weapon at the attacker's lower extremities and fire the weapon.  (Disclaimer:  I've trained this way with pistols, shotguns and rifles (simunition guns, red guns, etc.,) but not with SMGs, though I should add that I am the survivor of a pistol takeaway while clearing a house––-with real ammo and playing for keeps.  I will take a long gun any day.)

This.  5.56 is far more effective than a pistol round.  There are no benefits to using a pistol caliber carbine over an actual rifle unless suppression is a requirement.

True, but if the choice is MP5 in 9mm or a pistol, I'll take the SMG.  Case in point––the missus simply can't be talked into liking rifles, so the options for her for HD are one of her pistols, or her UZI.  I far prefer her having the UZI handy.

I considered that, but I wanted a .45 ACP SMG. I'm not a fan of the 9mm or the open bolt firing either.
Just a personal preference. The 11 is a neat gun though and it's a blast to shoot.

The subgun is closer to your body unless the handgun is holstered or in a retention position.  Three points of contact closer to your body with a sling attaching it to your body makes the sub gun much harder to knock out of your hands.

Retention positions are the only ways that a handgun makes a smaller overall profile.  The subgun is tucked into your shoulder, your arms are in tighter, making the overall profile smaller than having a handgun with your hands fully extended.

I own a pistol caliber subgun, and would choose it for making any sort of entry over a handgun.



If close quarters or grabbing is a concern, take the can off. It also has a rail on the bottom for VFG if needed.
