So, after researching 10mm Glocks, I'm seriously considering a Glock 20sf. I think the 10mm round is something I would really enjoy, and I love the feel of my G21sf. However, after seeing how happy people are with their G21 Gen 4s, I'm wondering whether I should wait for the G20 Gen 4. I found a few posts where people claim to have contacted Glock, and Glock purportedly said the G20 is coming soon. But, I also found a few posts where people said that they contacted Glock, and Glock informed them they don't release this information to the public. I'm not quite sure why Glock would release this info, as it seems as if any indication that the G20 Gen 4 is coming soon would result in less G20sf sales. Anyone have any predictions? Is there any way to predict when the G20 Gen 4 will be released? Is it even possible to predict? I suppose I should just contact Glock myself--just figured I'd check here first. Thanks.
