Excellent choice!
Bought this to run on a G20 Gen 4 so I could mount a suppressor. The suppressor is also an LWD product! Oh, and I replaced the recoil spring with an LWD part, AND the extractor with an LWD part. Very happy with the whole rig. The barrel drops in and runs fine, the recoil spring is a bit more stout and the extractor is a machined part, not LMI. I love my Glocks, but LWD makes 'em better.
