To my eye/feel the 43x and 48 have slightly deeper OR sharper grooves cut in the slide. So this is just a little extra security/additional dexterity during mag changes, failure to fire, etc. I practice both using the slide stop and slingshot and have both the 43 and 48 and so far just doing some dry...

The 42 version is ridiculously wide!! The 43, 43x, and 48 version is great. It just barely sticks out on those pistols and that's all I wanted and what I thought I was going to get.

These are awesome on Glocks, but the GSR-02 is not for a Glock 42. They make a GSR-01 just for the thinner Glock 42. One reviewer here said this GSR-02 fit his Glock 42, but it was very wide....so it will apparently fit, but it's too big for the narrower G42.This being said, these are the best slide rackers. They're sturdy (metal inside), they fit great and only protrude slightly. They keep your hand from slipping off the slide, and you can even rack with two fingers. Perfect for racking Glock's strong dual recoil springs.
Pros:
None
Cons:
NOT FOR GLOCK 42
Would recommend: Yes
