Serendipity!
I've been carrying this since July, with My LC9. and loving it, I'm very happy with it as a deep conceal, even in shorts and a tee shirt.
Believe it or not, the extra round in the mag has made a slight difference in the gun handle printing a bit in some outfits. I keep one 7 round mag with the stock flat bottom for the really light outfits.
Now that Fall is here, not that you would know it by the weather, I'm thinking I would like to inside carry My FNS9. After putting it on my Galco Paddle holster for the FN, it didn't seem that any kind of discreet carry with the FN would be possible. It looks like I have a sack full of hamburgers stuffed under my shirt with the Galco. No biggie, It makes a great competitive shoot and an OC for scouting about in the woods.
Today I wondered just for general amusement how the FN would do in my Kholster Baby Moon. It doesn't just kind of fit, it is a perfect fit. no snags, hang ups, sags or gaps. It is secure once holstered, it draws and holsters as smooth as the LC9, better in fact, because the loaded chamber indicator on the LC9 gives a little resistance when you are holstering it.
I have it under a baggy Tee shirt and it is hard to spot even if you know it's there. I can bend and move with it no problem. I didn't imagine transitioning to a bigger pistol would be that easy.
