Ran into a malfunction during an IDPA Classifier last week. I've now been able to repeatably demonstrate the malfunction. I have a video showing the problem, but I'm not sure how to upload it for y'all to see. YouTube? (Edit: Never tried uploading to YouTube before. Have no idea if this will work. [ame]http://youtu.be/C0EFCiLlrsU[/ame] ) Problem occurs when a round is in the chamber. During the Classifier, after 1 round was fired, the slide did not return all the way back into battery. It stopped about 1/8" short of being in battery. Almost always a normal cycle returns the slide with far more than enough momentum to get all the way into battery. I don't know for sure whether the slide went into battery and bounced back out or whether it stopped short. I can repeat this situation using snap caps and manually cycling the slide. After loading a snap cap, I can perform a very gentle chamber check. Pull the slide back just far enough to see the snap cap color. Then gently return the slide forward. The slide hangs up 1/8" short of battery. When the gun is in this condition, the slightest nudge is enough to finish the job and return to battery. If I point the muzzle straight down, the weight of the slide is generally enough to get back into battery. When I pinch the slide back slowly I can see the chamber end of the barrel drop down slightly. When I return the slide slowly, the barrel does not push back up until the slide gets that slight extra nudge. Any thoughts?
