21SF here. My hand fit the 21 but the 21SF really fit my hand. A recommendation in addition to what others have already stated: beside gripping both side-by-side, try renting both and firing both side-by-side. I was told and believe, the more I'm able to control the grip, the better I'm able to control the gun and my shot.
has anyone heard, seen, or own a new G21sf Gen4? Or do they even exist? I'm hearing that these just came out and are even better for smaller hands than the Gen4 21s, but don't see anything about them on the Glock website. Any help will be great.
I have a G21 SF as a duty weapon, but mine is Gen3. I love it. My personal weapon is the regular G21. I don't notice a vast difference in the grips. The Gen4 G22 I have is an excellent weapon, and I like the fact that you can change the grips if you want to. There's also a grip system you can buy through glockstore that allows you to change the grip of your Glock to be more like a Sig if you wanted.
