I just got a Don Hume leather belt holster for my Phantom and SP-01 Tactical. I got the H721 No. 41 (Glock 21), holster.... it fits the Tactical O.K. and the Phantom better, but the strap is a bit loose, due to the shape of the G-21 but is usable. I wonder if a Glock 17 holster would even be a better fit (Not sure!). The Phantom fits a bit snug, in the G-21's holster but I think it will break in and be fine. It is a good quality holster, which I would buy again.
I got it at Gunners alley for $52 bucks.

I do use it as a bedside gun most of the time, so it lives with the light mounted!

P.S. I did but a Falco holster first.... I hate to say it.... but the Falco isn't even in the same league..... it is not terrible, but soft and thin leather.... I don't trust it,
I felt that I needed a better holster so had to go out and buy the Don Hume, with much superior quality.
