Ordered an STI Eagle 5.0 ..... but in 9mm Para (9x19) just to find after a little research on the net that the 1911 designs often tend to have feeding problems with the 9mm. Does anyone know if this also applies to the highcap "2011" designs with ramped barrels? The gun is ordered from Dawson and includes his reliablility package, hope he makes it run . ..

Hello. I have the single-stack STI Trojan in 9mm an it has never failed to feed or extract. It has failed to lock the slide back on the last shot with standard pressure ammo but never with the warmer handloads or +P that I shoot. Hopefully your STI will work just as reliably. A friend also has the 9mm Trojan and has zero problems with his and as he shoots primarily standard velocity, he replaced the recoil spring with one a pound or so lighter and his pistol runs 100%.

I have not tried the double-stack so I cannot comment on that but IF you have problems I suspect that they can be corrected without much trouble.

Best.

I can't comment on the STI guns but I bought my fiancee a Kimber Tactical Pro II in 9mm (also a 1911 style pistol) and there have been zero malfunctions in several hundred rounds thus far. This model also has a ramped barrel. I wouldn't sweat it too much, if you do enough reading on the web you'll find someone with negative comments on any firearm ever made. Good luck.

Thanks. It will be another 5 weeks until I get it and can try it out.

Many years ago a friend and myself both purchased Series 70 Colt Commanders in 9 mm, mine the light weight and his the all steel model. Both ran 100% even with our handloads.

As KCII said look long enough or hard enough and you'll find someone on the www that is dissatisfied with just about anything. :)

In 9mm the slide is a bit on the heavy side for the recoil impulse produced. You can reduce the power of the recoil and main springs, but too light will compromise feeding and ignition reliability.
If you run light loads you will run into problems with ejection and slide lock back. Mid range to heavy loads will run fine.
I would suspect that a commander sized slide would work well. On Novaks web site, they show a 9mm 1911 that has the top of the slide opened up like a Glock 34.
On the other hand Mr. Camp has a 6" Sti which he reports has excellent reliability. Maybe Sti has the 9mm worked out.

Hello. STI sends the 6" Trojan with a conventional 10-lb recoil spring due to the added weight of the barrel and slide.
It works fine with standard velocity and +P loads but fails to lock back about 3 times out of 5 with standard pressure and 5 out of 5 with +P. A friend dropped down to a 9-lb and his gun functions 100% with standard velocity and locks back w/o fail and seems fine with the hotter stuff I usually shoot.

Best.

My stainless Springfield starts to have feeding problems when I go to an eleven pound spring. I am using a twelve pound spring, and it is 100% on feed reliability.
I have 100% feed reliability, but not slide lock back with UMC or Winchester White box. I also have some problems with the ejection of the last round in the mag.
If I go to Blazer, everything works 100%. Defensive loads also run 100%.
It seems to me that a 9mm 1911 would present no problems to a hand loader. Some factory target loads are going to be marginal.
