Initially I purchased the DeSantis Nemesis pocket holster for the Kahr PM 9.
I saw in a catalog, though, one re-seller that listed the same model of Nemesis for PM 9 as being adequate for the Glock 26/27.
I decided to try it.
As I sit here typing I have a G 27 in the front pocket of my Wranglers inside the DeSantis Nemesis. Model N38BJMKZ0.
It's not ideal so I will probably be trying other pocket holsters. It very often won't let go of the pistol, depending on the lining of the pockets on the pants it's in.
It DOES cover the trigger for safety and holds the pistol upright.
It DOES break up the outline of either pistol. No one has asked if I have a pistol in my pocket nor completed the joke.
The G 27 is a chunky pistol for pocket carry but it's not impossible so long as your clothing is not too tight. I can't say I have totally forgotten that I'm carrying but at this stage I may not feel that way with any firearm on me.
Hopefully I'll find a holster that does the same things but also stays firmly in the pocket when I perform a presentation.
