9mm in a 1911 is a bit of a bastardization of the design due to the short cartridges. When my wife got on in 2002 we had a bit of a learning curve with it. The jam you are describing is often called a 'squirt' and can be worked out.

I talked to a friend who is a very dedicated 9mm shooter and he recommended a full power mainspring which I installed. From what I was told (and believe myself) the reduced power mainspring contributes to a higher slide velocity that can become problematic.

I then got a Wolff recoil spring calibration kit and ran the gamut finally settling on a 12 pound spring. This settled down the gun quite a bit though i did have the odd squirt. I did notice after about 3,000 rounds the gun smoothed out quite a bit and became as reliable as you would like in a match gun.

With the Springer 1911 it is very magazine sensitive. The magazines must be kept clean and the magazine springs must be fresh. I replaced mine with Wolff extra power springs and it did help with the slide locking back. I also learned that the gun does not like certain magazines. The Metalform magazines work the best, particularly the ones with the front ramp. My wife's springer will not feed the Cobra magazines worth a darn. I have not tried the Wilson magazines.

I also replaced the factory slide release with a Wilson bullet proof part. With the factory part it sometimes would release early. The new part helped solve that.

The springer 1911's are good guns, they just take an initial break in and some TLC. We have over 70,000 rounds through ours now.
