I guess I started shooting semi-autos during the old school days, so I always have used the slide release, except with my Glock 30SF. That release is difficult, so I use the slingshot with that one. I don't really think of hitting the release with the thumb as a fine motor skill. The slide release is much quicker, and I do not recall getting either an empty chamber or a jam after using it.
I have noted the same thing with standard Glock slide releases, and have replaced most with the slightly extended factory version.
Frankly I see it as no big deal to use either method. Just get the gun back in action!
