    are the 21 and 21sf use the same springs and parts? I know that the magazines are diffrent and the grip is smaller?

    Trigger housing is only difference. This is comparing standard Glock rail equipped 21 and 21sf.

    They use the very same magazines. The SF (Short Frame) grip is shorter, front to back, due to a reduction in the back strap.

    Thought the 21 and 21 SF used different trigger bars.

    They can use the same, newer magazines with the metal cutout in front. But the G21 will accept the old magazines without the cutout, where the G21SF won't.

    The 21 SF's all have the newer -1 trigger bar where some older 21's did not. The -1 trigger bar should be upgraded in any G21 that doesn't have one.

    FWIW - all new production G30, G29, G30 SF all have the newest -1- trigger bar which is not needed in any other models.

    Not quite correct. Only the G21SF that has an ambidextrous magazine release requires the newer style magazine with the cutout. If your G21SF has the traditional left side only magazine release, any G21 magazine can be used.
