recoil spring inducing malfunctions

[sheepdog566]

I have a gen 4 35 in which I replaced the factory recoil spring with a reducer ring, tungston guide rod, and 15 pound spring. When I shoot one handed, either strong or support hand I have malfunctions, usually fail to feed. I have to death grip the gun to get it to feed. When I put my factory recoil spring/guide rod back in everything works fine. Anyone else experience this?

Do you know what # the stock recoil spring is?

Have previously used a G34G4 factory spring in G35G4 with reduced power loads for GSSF, and it functioned perfectly.

Had a similar thing happen to me at this past weekend match, glock 35 gen4, with a Jager steel rod designed for the gen 4, so no reducer ring needed. Would up with 4 different jams during the course of fire. Almost certain that it was the recoil spring since it was my first match with it installed. Would figure that the problem didn't appear during practice

Mine only malfunctions when shooting one handed. If my grip is not solid as a rock it short strokes. When I put my factory guide rod back in I can shoot one handed with no malfunctions no matter how I grip the gun.

I guess the trial and error switching of parts frequently leads to negative responses. Many mechanical design parameters require the optimization of properties that are on opposite ends of the same stick. When the aftermarket claims to improve a certain property, you should ask them if there is an equal and opposite negative response in another property.
