Some pistols work fine with them, some don't.
I have never seen this. Ever. Perhaps you were using solvents or something harsh. Gun lube won't affect the polymer that buffs are made from. Glocks would be a spongy mess if that were the case.If you do decide to run them, keep the oil far away. It'll cause the plastic to soften and warp like crazy.
Happend to me the three times I ran them. Maybe it was a fluke.I have never seen this. Ever.
Here is a good reason to slingshot your slide: If you train with multiple platforms of the semi-auto pistol the slide stop release will not always be in the same position. Slingshotting the slide ensures that a round will be chambered quickly and efficiently with basically any type of semi auto you are running. It also allows more force to generate when you pull the slide back that extra little bit to ensure the next round is fully chambered. Sometimes when a semi auto gets real dirty just hitting the slide release will indeed release the slide, but the force may be less due to some dirt/debris and the next round may not fully chamber.Somewhere on this forum are posts showing Logman's shok buff setup using a steel washer in front of the buff to prevent it from getting cut up if your slide's dust cover has sharp corners (some do - some don't). All you need is a correct sized washer and 5 minutes with a file to shape it the same as the buff. The buff lasts for a VERY long time. Of course, in a lot of guns this will not allow you to "slingshot" the slide to release it. I have never seen a good reason to "slingshot" the slide anyway.
