Yeah, frankly even subcompact 9 mm (shields) and snubbies are too big or barely manageable during summer or limited concealment situations. Both are still tight with IWB. Both can be pocket carried but it is a full pocket with bulge.Make sure and use only brass cased ammo. Absolutely no steel cases. It will destroy the extractor.
You bought it for a pocket gun. Keep it as it is. I have micro 9mm's and other supposed carry guns but this one is the only one I carry anymore. If I could find something smaller I would take a serious look at it.
I think an LCP size gun is important for summer carry or tight fitting clothes.
