In this months Shooting Times I noticed in the grocery store, there was mention of the new 45 GAP. I think just by skimming the article it was partially developed for Glock (Glock Auto Pistol ?) Without having a chance to really read the article it seems to be a shorter round than the 45 Auto, similar in length to 9mm. Supposedly it still has comparable velocity, etc. of the 45 Auto in a shorter platform.
