For a defensive carry gun, how important is barrel length?

When it comes to "terminal ballistics" and a carry gun, how much does barrel length play into it? For example:

1. Kimber Solo with 2.7" barrel
2. XDs 9mm with 3.3" barrel
3. XDs 9mm 4.0 with 4" barrel

Assuming the same load is used, for instance 147gr Federal HST, is there going to be much difference in how the projectile will perform?
 
9x19mm vs .45acp .....

In 9x19mm(9mm Luger), Id say no. A 9mm defense bullet could work(cycle) in most 3" barrel pistols. Sub compacts are not ideal in terms of ballistics but they can work for some pistol calibers like the 9x19mm, .40S&W & .357sig.
I would not buy a .45acp with a barrel less than 4". Most .45acp LE & defense loads need a longer barrel to work properly. The Glock 36 .45acp is good but most sub compact .45acp models do not get the best performance from the ammunition due to the shorter tube.

The new XDs .45acp with 4" barrel is worth a look. S-A now has a buy a new pistol get 3 free magazines & a polymer mag holder. The offer runs until 10/2014. See the Springfield Armory website for details. :D
 
Amongst the barrel lengths 9mm. you mention, I'd forget the barrel length per se and figure out which gun I thought best so far as ergonomics, reliability, and load capacity.
If you REALLY want to worry about terminal ballistics then the XD with the 4" barrel, but the dead guys aren't gonna notice the difference much.

I think people worry far too much about "how the projectile will perform".

More important factors are reliability and shootability.

If your XD-S 4.0 is more comfortable to shoot than the 3.3, you will practice more and will be more proficient.

Some users have found the 4.0 to be more reliable.
 
Is it long enough to make the bullet perform? This will vary by ammunition selection.

Is it a comfortable length for you to conceal? This will vary be body type and size.
 
True, reliability and concealability are the most important. This is all for discussion sake, of course. The odds of me ever having to pull out a carry piece and shoot someone is extremely low anyway.

Currently I carry an XDs 9mm 4.0. However, my gunsmith friend just got a Kimber Solo and I am planning on shooting some rounds through it tonight. I like the idea of a smaller/lighter carry gun and have been intrigued by the Solo since I handled one at a gunshow. For my hand, it is one of the most comfortable guns out there. But I heard they kick like a mule, so I'll find that out later today.
 
If you research ammunition tests in gel media, the longer the barrel, the more expansion. Example is the Winchester Ranger ammo. In barrels less than 4" they don't expand well at all.

Other modern SD ammo will work fine in both short and long barrels. Speer even makes a short barrel version of the Gold Dot. I keep 124gr HST in my G19 and my Pt709
 
Not very. Assuming you have a well rounded caliber, and around 1.8 inch on a revolver and the 3 inch range on an auto. Sub compact size is fine for concealed carry.
 
If you can hit the target I don't think it matters at all. Worry about hitting the target and don't worry about how fast the bullet is going.
 
For a carry gun, barrel length may not be the limiting factor many folks think. With many or even most holsters, the barrel will be pointing down, concealed under a jacket or inside the pants or skirt. Only with something like an under-arm horizontal holster or an upside down type (are any made any more?) would a longer barrel be a seriously limiting factor. In most cases, the difference between, say, a 2" and a 4" barrel would not be significant.

This has more to do with bullet construction.

Terminal Performance is going to be different in each gun. Charge, Twist Rate, Construction, Type Of Action and Barrel Length are going to all play factors in how a bullet performs.

Roger That, just carry the gun you can shoot accurately and reliably
 
With the right ammo, you will do fine with a barrel shorter that 4". As a general rule, these short guns would do better with 124 as the "heavy weight" 147 much better in longer barrels, which are not a problem unless you are concealing it. then the question is a choice you must make. In that case, I chose the Glock 17 4.5 inch barrel. In retrospect, maybe the 19 or 23 I think right at or just under 4 inch barrel, with 9mm conversion barrel may have been a better choice for me.

I considered a Solo, but ended up with the S&W Shield, which conceals easily. Less than 1 inch thick, also available in .40.

You might also consider .45, Glock 30, 36, 30 SF, or 30S are great choices, as is the Springfield arms XD in .45 Here I chose the 30S...surprisingly accurate. The XD is way flatter, easier to conceal. I have heard nothing but raves on the 9mm XD, It was Recoil magazines choice a while back when they reviewed the .45 version, they could not say enough good about it, despite a recall that was on at the time.

Yeah, I am kind of a Glock guy, but remember...if the gun does, heaven forbid ever get used in a self defense situation, it will sit in evidence for a while. for less than 600 you can replace most any Glock, Kimbers are more expensive, as are others. I sure did like the looks of the Solo I saw, I think that particular version was just over 800 at the time. Beautiful gun.
 
Yes, the Solo is a great looking and feeling gun. The one at the gunshow I saw that I REALLY liked was the new DC model. But with its short barrel, I was wondering about how well it would do. I think that has been answered well enough here.

As of now, though, I'm good with the long barrel XDs 9mm. Just a tad big and heavy than I'd like, but certainly not a deal breaker [obviously, since I'm carrying it].
 
For my purposes, the only consideration I every give to barrel length is in regard to the distance between front and rear sights. I'm more likely to be more accurate with a Sig 226 than I am with a Sig 938. I suspect that the barrel length (as it relates to slide length) is the reason. Both are shooting the same round.
 
Yeah, that longer sight radius can help for potentially making more accurate shots.
 
Rule one of the gunfight: "Have a gun!"

If the shorter barrel means you'll actually carry it, that's the one to get. Conversely, its smart to carry the largest gun you can comfortably conceal.

For me that means 3.5" or less barrel length and single stack. YMMV.
 
Ditto Posts 17 & 18. The real issue is the length of the sight radius. Longer barrel (slide) means more distance between front and rear sights hence making it easier to align the sights properly.

The FBI considers penetration to be the most important issue so matching the ammunition to the gun would be needed.

Fine....

I agree to carry a pistol that fits your needs. For most US shooters & CCW license holders, that's a Glock 19/23, Commander 1911 or a SIG P229 size pistol.
I'd add that it's not what works, but what works best.
Barrels are meant to increase vel & burn powder. Bruce Gray of Gray Guns Inc, known for SIG P series & HK custom pistols, advises carrying at least a 4" barrel in .45acp.
You want a semi auto pistol that feeds & cycles JHP or defense rounds 100%.
A compact pocket pistol may be easy to carry or light, but it's worthless if it can not function properly.
 
Purses....

Yeah..
It's kinda hard to conceal a S&W N frame .44magnum with a 8 3/8" barrel in a purse.
:rolleyes:

FWIW; S&W has stated in the recent past that the J frame .38spl 5 shot is still the best seller.
 
Guys, my main focus was on the pistols in the OP, specifically 9mm pistols.

However, I am aware that others, with different calibers, can use this thread as well. So have at it.
 
Ballistics are definitely affected by barrel length but considering a self defense shooting is going to be pretty close it doesn't even matter. It's not like you and the BG are gonna be shooting it out at 50 yards
