Springfield 1911 9mm (P1934L)

[Tree Rat]

Why the full profile barrel at the bushing, tapering to thin back to the locking lugs?......and with no integral ramp?

Good set-up or bad and why? Anybody have one of these that they can comment on?

Tree Rat:

I have a Parkerized Springfield 9mm from the

early 1990s like that. I also have a loaded

stainless 9mm from 2001 that has the integral

feed ramp without the taper.

I have not been able to tell any difference

between the two configurations as far a

reliability.

How about some pictures of your new gun and

barrel! Maybe it isn't exactly like my 1990s

gun.

My 2001 Springfield full size 9mm was shipped

with a 45acp slide stop instead of the

38super/9mm slide stop. This was causing the

slide not to lock back on the last round

intermittently.

Just because your Springfield slide stop has

a nine on it, doesn't necessarily mean that

it is a 9mm/38super.

I have read of incidents where this happened

to STI and Kimber owners as well.

You can determine if your slide lock is

correct by measuring how long the protrusion

is that the magazine follower pushes up on. A

45 slide stop protrudes about .200". A 9mm

protrudes about .230".

To measure the lug length, remove the slide

stop from the gun. The lug length is measured

from the inside flat to the tip of the lug. I

use the ass end of my dial caliper to do the

measurement.

I replaced the slide stop with a Wilson's 9mm

which solved the problem.

By the way, to get the gun to lock back 100%

of the time, I use an 11.0lb recoil spring.

Springfield shipped the gun with the 11.0lb

spring. I tried a 14.0lb because in some

circles that is considered standard.

I changed the springs in all of my 9mm

magazines with the spacer in the back with

Wolf extra power springs which helped feeding

immensely.

The magazines with the spacer in the back are

only reliable with 115gr FMJ ammo in my guns.

I tried one of the new modified Springfield

9mm magazines with the crimp in the front.

These are the new ones modified by and

available only through the Springfield custom

shop at this time (the older ones with the

front crimp gave some people problems). With

the new magazine, 124gr bullets now work

fine. I haven't tried any hollow points in my

9mm 1911s because I use .45s for self

defense.

TR,

I almost bought that exact same gun but went with a .38 super 1991 Colt instead.  While I was shopping I noticed the "bump" at the end of the barrel and I asked the same question you are asking to several dealers.  They all told me it was so the gun could use a standard (.45) bushing.  So that is what I know.  How does the gun shoot?

Hmmmm......2001 gun's had full profile ramped  barrel's?

I heard the same explanation regarding the use of the 45 ACP bushing as well........

I would think caliber (bore ID) would not affect bushing size. Full profile 9mm/38 Super or .40 barrel's simply have a heavier profile with a reduced bore diameter in those calibers and lock up with a standard barrel bushing because the barrel OD would be the same.....or maybe I'm missing something?

Kimber's 38 Super and .40 guns have full profile barrels and standard bushings, as well Nowlin and SVI for 9mm......all with ramps.

I don't have the gun as I'm shopping as well. Kinda pissing me off. Think I'll call Springfield.

I saw a new Springfield 9mm Target yesterday. I noticed they now come with a ramped barrel. I also noticed they still come with the old style, back spacer in the magazines.

Tree Rat:

I measured the OD of the barrel at the muzzle

on several of my guns. They measured as

follows:

.579" - Colt Gold Cup .45acp

.580" - Early 1990s Springfield 9mm, yes

tapered barrel and no feed ramp

.580" - 2001 loaded Springfield 9mm, no taper

and integral feed ramp

.499" - Early 1990s Colt 9mm, no taper and no feed ramp

Thanks SS.............

The Colt set-up was known for it's thin barrel and non-standard bushing bushing set-up.

Does anyboby know the diameter at the taper for the Springfield taper barrel?........bet it's close to that Colt barrel.....

Tree Rat:

.510" at narrowest part of barrel - Early

1990s Springfield 9mm, yes tapered barrel and

no feed ramp.

I would love to know how this compares to the

new guns. By the way this barrel is carbon

steel. I assume the new tapered ones are

stainless steel?

[Tree Rat]

New barrels are carbon steel.......

Talked to the custom shop today, seems they chose a non-heavy 9mm chamber barrel profile but wanted to keep a standard bushing (hence the taper). still don't get it..........

All of the 9mm SA guns that I looked at were stainless and had stainless barrels.  The tapered barrel looked more like a bump than a taper on the models I examined.  Just using a heavier barrel would have been better I would think.  The Colt .38 super I bought does have a skinny barrel, no taper, and a non standard bushing to accomodate the skinny barrel.
