To those of you with a Glock (17, 19, 20, 21, etc). Can someone take the measurements as in the picture and either post them for me or PM me with them.

I'm looking to get a holster and cannot for love nor money find one to suit. It's not for a Glock, but as the muzzle area is the same shape i'm hoping if the dimensions are the same or close that one for a Glock might suit.
There is no need to post what model you have as the holster i'm looking at is designed as a universal one for all types of Glocks.
Thanks in advance.
