45 GAP from 625 ?

The biggest thing to me about .45 GAP is that you actually seem to lose capacity from shrinking it down so you can fit it in a smaller frame. Not like say, .40 S&W where at least a Glock 20 and 22 are the same capacity. With the Glock 37 and 21 you actually lose 3 rounds in a full-size duty format. That to me makes it seem pretty pointless.

It was to get the punch of a G21 in a G17 size gun. I carried a G37 on duty and loved shooting it.
