Is 45ACP more accurate than 9mm?

[Aedrick]

I've heard tat 45ACP is more accurate than 9mm, is that true? I'm going to get a Kimber ultra carry II and those babies come in 45 and 9... I prefer to get it in 9, but if the 45 is more accurate, than I'm willing to make the caliber jump for that gun.

[marvin]

maybe out of a super tuned target gun the .45 might be more accurate. but out of the ultra carry it could go either way.

[Jim Watson]

Agreed, you will not see a difference in a short factory gun like that.

In target guns, the .45 can be made accurate enough that most shooters use their .45 for NRA Centerfire where a .38 used to be standard. Less expense, only two guns to learn instead of three.

But the 9mm can be made accurate enough that the Beretta is common in Service Pistol versus the harder kicking .45 with hardball.

[Allman]

Accuracy is far more a function of the shooter than the gun.

Actually, accuracy is the function of the shooter, precision a function of the gun and/or caliber.

You can shoot groups accurately to within the limits of the precision of the gun, whether highly precision or not precision at all. You can also shoot groups very inaccurately with a highly precision gun.

No matter what anyone says, very few shooters can consistently shoot to the precision of the gun they are shooting, particularly in a stressful situation.

You're much better off matching the ergonomics of the gun to yourself than trying to find the finest and most precision gun and caliber then having it be difficult for you to shoot accurately.

How accurate are YOU?

YOU do your part, either caliber will do theirs.

I don't think the 45acp is inherently more accurate than the 9mm, but it's more to do with the pistol itself. I think there is less variation in bore dia. from one manuf. than another in 45acp & the same w/ components. This could give the 45acp a little advantage.

Correct,I shot better with my SA XD45 then my G17,but I shoot better with my CZ 75B 9mm then my SA XD45 :wavey:

[SIGShooter]

My Wilson CQB is far more accurate than my G17/G19.

However, that's not because of the caliber. It's because of the way the gun is built.

I've shot Kimber, SA, Colt, Wilson, Les Bear, Ed Brown etc...

They were all more accurate than the others in many different ways. Again, it's not the caliber, it's the way the gun is made.

I think the most important thing you should worry about is your skill and mindset. If you shoot great with one caliber over the other, go with the better one. If you shoot better with one platform over another, go with the better one. Make sure your weapon likes what you feed it and make sure you know what your weapon is capable of. Make sure that you know what you're capable of when it comes to weapon handling.

Now as for the Kimber Ultra Carry II...

Owned one and these are my thoughts...

Not very accurate at extended ranges
Didn't many "Standard Loadings"
-WWB FMJ
-WWB JHP
-Hornady FMJ
-Hornady TAP
-Winchester Ranger
-Speer GDHP
-Remington GS
-Federal HST
-Federal Hydra Shok
Many, many, many malfunctions
-Helps with your failure drills though
Rusted right out of the box
Customer service sucks!
-Asked about the rusty sights being replaced (2 days after purchase) they said if I pay for it they will do it
That weird drop safety pin thingy they have in there
Disassembly was a pure *****
-You needed tools (Very small ones at that)
-And yes that little "L" shaped thing they give you is a "Tool"

Of course, Kimber makes some awesome full size 1911s.

Just my humble thoughts and opinions.

Stay safe and keep your powder dry!

[Aedrick]

Wow, now that puts a huge ax right through my plan to picking up the Kimber tomorrow morning... From what I heard from others, it sounds like a hit and miss with Kimber. I don't know if I want to spend $1000+ on a gun and gamble...

I recently picked up my Kimber Ultra CDP II. It has had 372 rounds through it so far. It is a little snappy, but less so than my SIG P245. It is very accurate for a pistol with such a short sight radius. It holds 7 + 1 rounds and is close in size to my G26. The Ultra has a shorter slide but a longer grip. I would suggest going with the 45, and I do like the 9mm.

[magiaaron]

I would imagine that your gun and you will not be able to wring the full accuracy potential out of either bullet. The "ultra carry II" has only a 3" barrel. I'd think that would make either bullet less accurate. And, the short sight radius would make it harder to be accurate, too. I'd say it all depends on how good you are. :)

FWIW, sight radius has mlore to do with accuracy than the shorter bbl. My OM shoots almost as well as my match grade 1911 to 15yds. After that, the shorter sight radius starts to cut into my accuracy @ 25yds & beyond.

It is no secret in our area that I despise 1911's. Like any other store, you sell more of what you push, particularly if you really believe in it. Such is the case with Glock handguns here at Southwest Shooting Authority. I can honestly say that each every used Kimber we've ever had in here, which is quite a few, has been traded in on a Glock purely because of reliability issues.
I went out with 2 friends one day and popped of about 800 rounds through 3 different Glocks without a single hiccup of an kind. One of my friends and I were not surprised and didn't think anything of it. When we got ready to leave, the 3rd guy said, "Let me put a few rounds through my new Tactical Custom II before we go". He knelt down, racked the slide, took careful aim and BANG, CLICK.... $#!$#@%%^&*&()(&(*^&^$%$@%@$#^%*&*)_*(&*&%&%$#%^#%@ this POS!! He promptly cleaned it up, brought it down to the shop and traded it for 2 Glocks. :supergrin:

And what are you going to do with the dud?

Actually, it can be hit or miss with any 1911 smaller than a commander. I'm not a huge fan of micro 1911s. That said, the recent models are much better than models in the past.

[AR-Jim]

^^ This man ^^ knows what he is talking about when it comes to 1911's.

Trust me on this one.

[20mmauto]

I believe the 9mm has a flatter trajetory, just slightly.

I had a SA Micro Compact. I never had a single failure of any kind with that weapon. I was able to shoot the crappiest ammo through it and the weapon did what it was supposed to do everytime. It was my wife's favorite gun to shoot and carry.

I kick myself in he arse when I think that I sold it.

[DaveA]

Get a S&W 1911. I challenge anyone here to tell me a story about how terrible they are, even with the external extractor. All you'll ever hear is positive from anyone who owns one. :tongueout:

[glock2740]

I wish I could shoot as good as my guns would allow.
