Glocks with Switches GET STITCHES...
This has been done in the past with other semi autos, notably the early AR15 which could accept a Lighning Link, the KG-9 which could be converted by filing the bolt, the open bolt MACs which could be converted multiple ways, and the Uzi which just needed the bolt and recoil spring replaced and a bit of filing.
All were banned, but grandfathered so not unlawful to own, the manufacturers all made small changes to make them less easy to convert.
Supposedly, Glock is the most popular handgun platform in America.
Soooo..... do I rush to pick up a couple G17s now that I wanted to add to the safe, or wait for the glockarians to sell off old models when they rush to the newest version?

If you already have Gen 3/4 models (or even Gen 5), I'd buy some spare parts. I never loved the Glock frames, but there are some awesome aftermarket frames. Lone Wolf Arms makes one that is exceptional (at least for me). I've been thinking of buying a few frames to replace the crappy frames on my Gen 4's, but really, there is so much out there to consider these days.
Pretty good explanation of the legal situation: https://youtu.be/FLBhNxEOERI?si=-aEIx88bf0J8CIfE
