Question: Will it fit a 30S?
Document: I bought 3 of these, they fit perfectly and do a Great job of locking and releasing the slide of my G19.
Fit perfectly and it wasn't hard to put on at all. My husband loved it. Great alternative because his gift was late. Very fast shipping. Can't say much more because he hasonly had it a day or so.
I installed this on my Gen 3 Glock 19c and it fit perfect and works great. I wouldn't put it on a carry gun but I love it on my range gun!
Didn't really have an issue with the 19 Gen4 Slide Release / Slide Lock, but the factory G21 Gen4 was just too small. Replaced both so all of my Glocks would be uniform. These fit perfectly, make it EASY to release the slide on a fresh mag, even on the chunky G21. Highly suggest. A well-trained monkey can install these.
put this in in about 30 seconds due to Glocks designAfter owning a 23 for almost 20 years it was time to refresh and upgrade a few things and one thing that always bothered me a bit was the small low profile slide stop  a holdover from my 1911 days was tripping the stop after a reload which is now easier thanks to Mr. Vickers redesign  and I don't subscribe to the slingshot method of slide release preferring either thumb to trip it on the rare occasion I run the pistol dry.
You work with this, work it. Put this in and it make it easiers for the slides to go in.
Works well with both the Gen3 and Gen4 models. It's a  good &#34;in between&#34; option for the standard and extended slide stop lever. It depends on the individual's hand size and grip whether it will be beneficial or not. I have them on all three of my Glocks.
Works great for me. Appears to be good quality and installed in a couple minutes. The design is basically the same as the stock Glock item, except that the shelf for your thumb to push downward on is quite a bit wider - which is exactly what I wanted. With the factory slide stop, I found it difficult to get a good purchase on it with my thumb. And I do like to have the option of releasing the slide with one hand. This totally fixes that problem.
Vickers slide stop works great . put it on my G30 ,G23 , G27 , G26 and G19 hope to get more.
This slide stop definitely outdoes the stock slide stop on the Gen 4's. I get a much better grip when I need to lock the slide back.
Answer: no
