Yes they do, but at a cost.
$3000+

Gun or caliber

Apparently you didn't read the whole sentence. It's not the pistol, it's the calibre (9mm)

Even the best bullseye pistols chambered in 9mm struggle to retain a 2" group at 25 yards. Your standard 9mm 1911 won't be seen on the shooting line of a bullseye event. I would class the Pro Series as a standard pistol.

Shooting a 1911 chambered in 9mm is very pleasant. They are soft shooting and fun to plink with, ammunition is fairly inexpensive. I have Colt Competition Model in 9mm. It's fun to shoot but it's not a bullseye pistol and I wouldn't expect bullseye accuracy from it.

In the above post you say it’s not the pistol it’s the caliber. When somebody later in the thread shows you an incredibly accurate 9 mm. You say well I was talking about the gun. So which is it? 9mms are inaccurate or 1911s are inaccurate? Because I don’t think either are inaccurate. I have a SW Pro 1911 in 9 mm. I don’t think it is inaccurate at all compared to any production gun. And it is easier to shoot accurately than many guns due to a heavy weight, excellent sights and the 9mm cartridge.

I didn't say that 1911's are inaccurate at all. The thread is drifting away from it's original question.
The O.P. is looking for a box stock 1911 pistol that shoots a 2" group at 25 yards chambered in 9mm and was interested in the Pro Series 9mm with fixed sights.
I've never seen a 1911 chambered in 9mm consistantly shoot a 2" group at 25 yards. I'm not talking about a high end pistol, like is featured in the above video. I'm talking about an affordable "standard" production-not highly customized and tweaked expensive variety.
If you know of one, please share.

You are correct. I wanted to know about an out of the box SW1911 9mm. M29since14 seems to have the same issue that my friend had that got me concerned to start off with.

Maybe 2 inches is too much to ask for but I don't want 7 inch groups because of mechanical flyers not human error. Cause that means the pistol cannot group. Which is the case with my friend's pistol. Look he has the resources and pretty much rebuilt the gun to the point that all that was left original was the frame.

I'm not keen to do that. I just want to know if these non-grouping guns are the exception rather than the rule. We have too few SW1911's in 9mm here to really find out. In fact I only know of this one guy that has one so far. Hence me asking you guys since I figured there must be more sold on your side.

The Sig 9mm 1911 gets all the votes in our National Team's Classic team. I'm sure it is a fine pistol but I'm a Smith fan and I'd rather go with the that. I find it better looking anyway. Not that looks count for everything but it is a factor.

potentpoefie,

You may be able to find some low cost accuracy improvement in the slide stop pin dimensions and the barrel bushing. Using drill bits as pin gauges you can see what size pin fits and improves lower lug contact and lock-up before thumbing through the Brownell's catalog for parts. EGW does a good job on barrel bushings. Also examine the barrel crown carefully.

On Bullseye pistols rear hood fit in the top of the breachface gives accuracy improvements. Slide fit to frame doesn't do as much as most people believe.

These are just a few quick notes. Accuracy tuning 1911s is a deep rabbit hole due to age of the platform and the work of the military teams to wring out accuracy for their competition teams using service type pistols. The same tuning was done when the Berretta M9 was issued and now the SIG P320 is being refined.

Thing is, here in South Africa, the barrel is a licensed part and to have another barrel fitted will cost me another 3 months in waiting time just to get another license for a new barrel.

...

A common practice in the past was to weld up the rear hood of the barrel and refit it to the slide.

Good ammunition helps. I found recently that Fiocchi 115g 9mm FMJ shot to call at 25 yards in my recently acquired Glock. Attached is ten shots on a NRA B-8 target shot standing at a Slow Fire pace with two hands. I gave this target to my first shooting instructor. Once I get used to the trigger I think I will be able to hold the ten ring. When I get some Atlanta Arms Elite ammunition I want to see how it shoots at 50 yards.

Well I think I might just pull the trigger on the purchase and roll the dice. Maybe I get lucky and my gun can group. It seems after all the replies we only had one member really that had this issue.

This of course doesn't mean it is only limited to his pistol but oh well. Nothing in life is certain.

But then I look at the Sig Match Elite and it is pretty much a 2" gun right out of the box with all kinds of ammo. That's basically 2" at 25 yards. Look at the accuracy tests at the end of the video.

That from a $1000 pistol. Well just over. Cheaper than the S&W.

I think a 2" group at 25 yards with a 9mm is asking a lot from a 1911 pattern pistol. There are better choices, but also at a cost. My opinion only.

My STI Trojans in 9mm are easily capable of 2” groups at 25 yards. If I worked at all on developing an accurate load, either one would probably do better.
