Will theses work for the Glock 19 Gen 4?

According to Amazon’s review on this same product it is “not” compatible with a gen 4 Glock 19.

Great for Reloads by Steven, September 28, 2019
Either +P+ with a stiff spring, or reduced load with a soft spring. These sure smooth out the final impact of the slide! Some light modifying was required to have the buffer fit flush to the P80 frame.

Just okay, nothing special by Jerry, Verified Owner, December 3, 2018
I am not sure I could tell a difference before and after installing. I ended up not using because of this reason, since less is usually better. I likely would have returned these if I would have opened them sooner. In short, they were of no use to me...
