If you want a piggy back style my comments here can't help you but I will say I use a Tulster IWB holster for my EDC PPS & absolutely love it.I recently got a teir 1 AGIS for my Springfield. I love it. I want to get an axis slim for my pps but they only make it for the newer pps. Any types out there that compare?
I combine their holster with the NeoMag product for carrying spare mag(s). Again, love this item as well.
Full disclosure: I don't work for Tulster or know anyone that does. I also use multiple other companies to supply my holsters for other pieces / applications.
