In case you may be looking for a low-profile, minimalistic rig for your G30 - or just love the Stow-N-Go for your other Glocks - the STO440 fitting the XD works for the Glock 30. I was a little bummed when I found the Stow-N-Go was not made for the G30 as I like this rig (using a heavy belt
) for my G26 and G19. Slight mods I did were adding a line of stiching at the trigger guard to tighter up the fit and trimming about .25" off the muzzle. Fits and works like my Stow-N-Go for my G26 and G19. I can't stress a good quality, heavy gun belt enough, but I digress on that. Mine is the G30 Gen2.5, but you can see from the pic there is plenty of room for the rail. Just letting y'al know.
