THE HOLSTER STORE | Glock 29 30 Gun Holsters
I have the Pro Carry LT for my G30 and have no problem with it except I should have got the forward cant (my mistake). I also added the slide guard shield, which is longer than needed but trimmed right down with sharp scissors.
The HD version appears to ride a tad higher if that matters to you.
Good prices, good quality, came within a week, strong metal clip.
