Too much or too heavy of grease will cause malfunctions especially with light recoiling calibers like 9mm or target .45's.
I had lithium grease (heavy hardware store grease) choke my P226 9mm.
I've never had an issue with Slide Glide Lite. I used it in 50 degree weather recently with a Sig .22lr conversion and it gave the same performance as FP-10 oil. Subsonics failed to cycle with both, and full power stuff did not with both.
I ran SGL in my P220 with light target loads out doors this past winter here in MN, no problems even though it was well below the recommended minimum temp.
On a gun with full length rails like a Sig or 1911, any grease will reduce recoil slightly by slowing the slide slightly more than oil would. Maybe the stringy aspect of SG helps a little. I never noticed the difference, but in theory, it should help a little.
If it's running down your gun or causing malfunctions, the wrong grade was used, or it was applied too heavily, a common mistake with any grease.
I use a dab about the size of a grain of rice, maybe two grains of rice, and apply it with a small stiff artist brush. That's enough to lube full length rails and the barrel. It doesn't belong in the trigger group. I also like it at the trigger bar/connecter interface on Glocks. Oil everywhere else.
