I use the Lamy Pico this fits perfectly and does not slip out.
Also I use the Mini Maglite.
For side wearing, the Leatherman falls at open flap out easily, this is the only shortcoming. But you get used to it pretty quickly why no star deduction. Despite the mangelden shipping times by Amazon.
The holster is not too bulky, even with a little paunch suppressed because sitting nothing. Just awesome!
