I've seen videos on YouTube that say you should be able to manipulate all the controls on your handgun without breaking your shooting grip. I own a SIG SP 2022 that has the smallest sized factory grip. I have no problems manipulating the slide stop on it without breaking my shooting grip. My thumb just reaches the decocking lever in order for me to drop the hammer. The magazine release, however, I have to break my shooting grip to press in order to release the magazine. I rented a Gen4 Glock 19 to see if I liked how it shoots and how it felt. I really liked the size and I could actually release the magazine without breaking my shooting grip. I could also reach the slide stop but it wasn't as easy to manipulate since it didn't jut out. I imagine an extended slide stop would fix that issue. How important is being able to change magazines without breaking your shooting grip? How important is being able to manipulate the slide stop without breaking your shooting grip? Is one more important than the other?
