I purchased a new Gen 3 Glock 19 and after only having put about 500 rds through it I replaced the recoil assembly with a steel guide rod and a Wolf factory standard weight recoil spring. After about 1,000 rounds and several cleanings the slide began to "stick" during forward movement. The weapon never had a problem cycling, as this only happened when I would slowly let the slide forward (with or without chambering a round).
With the steel guide rod, it was impossible to get the slide to fully move into battery without racking the slide back and quickly dropping it. As this was never a problem with the original recoil assembly, I replaced the steel assembly with the factory one. The slide still "sticks" when I slowly ease it into forward battery but I can push on the rear of the slide to get the weapon to move into battery after it "catches" just before it locks into forward battery. With the wolf steel guide rod I would have to rack the slide rearward after it "caught" and let it slam forward to return the weapon into battery (I could not push the slide the rest of the way into battery like I can with the factory recoil assembly in place).
When I fired the weapon before I replaced the factory recoil assembly and before I put about 1,000 rounds through the weapon with the Wolf rod and spring in it this was NEVER an issue. Once again, this is more of an annoyance as the weapon functions fine on the range as long as I let the slide slam forward when loading it. I am hoping someone can tell me whether this is a lubrication or cleaning issue I need to take care of?
I apologize for the LONG description but I don't have a picture which would indeed be worth a thousand words. Thanks for the help in advance.
You should replace everything back to factory and do not let the slide move forward slowly. Use the slingshot method to rack the slide or let the slide stop release it under spring pressure. Welcome to the forum

If the slide stops when slowly letting it forward while not chambering a round, either your guide rod spring is weak or you're not lubricating enough. One small drop of oil/grease in each area indicated by the instruction manual is sufficient lubrication.

This is an interesting post! First, I'll agree with the others who replied on the matter of not easing the slide forward. The pistol is designed to operate with full movement of the slide, so you shouldn't expect the spring to be able to close the slide fully into battery if it is eased forward and not allowed full movement.
With that said, I can think of a couple of possible factors that would contribute to the behavior you're seeing with the Wolff guide rod and spring: lubrication and spring wear.
The Glock owner's manual instructs you to put a single drop of oil on the top of the barrel, where the round part meets the rectangular part (sorry, can't think of the technical terms). That's the last obvious point of friction I can think of where the pistol is going into battery. Although others will disagree, when I have a steel or tungsten guide rod in a Glock, I can't help myself, I always wipe some oil on the guide rod as I assemble the pistol.
Also, a light recoil spring, or one that is worn (several thousand rounds cycled), will obviously not close the slide as forcefully as would a strong one. I'm not sure of the expected life of recoil springs, but I do know that some people with competition guns replace springs every few thousand rounds. For a reasonably active shooter, that might take a year.
