Galco ankle glove
I got one, intending to use it as a stopgap until I could afford an Alessi.
And one day, I might even get that Alessi, too.
Really.

PS It works fine. No, I'm sure its not an Alessi. Yes, I'm sure Alessi is better. But I've been in many a foot-chase and the gun stays put. Good enough for government work.
