IWB holsters are great for concealment, but not as good for presentation as regular pancake holsters.
When I was looking for an IWB holster for a M&P compact, I looked at Galco first, but could only find the Summer Comfort model. I am not familiar with that model, but have used a Galco Royal Guard model with come success with another carry pistol.
Generally, with a leather IWB holster you want the suede portion to be on the outside; the rougher texture cuts down on the holster shifting laterally on the belt, or yawing. The Summer Comfort holster does not appear to have the exterior suede advantage (you may want to check on this with Galco).
Another thing to look for is natural coloring. Dye in IWB holsters can leach or run due to contact with sweat, which can do a number on portions of your wardrobe.
I finally decided to get a FIST holster in Ultra Thin Kydex for my M&P Compact. It does not have the suede roughness noted above, but that can be remedied if you want. The K6 models have a number of useful options, including choice of belt attachment style and size (and you can swap one for another), choice of cant, and choice of thickness (thin or ultra thin). Take a look at:

Personally, I prefer the single attachment point type found on the K6 models (I have two of them I use all the time). I do not like the holsters with the spread out double attachments (see, the K1 or the Hybrids for examples). Thus, I sacrifice some stability for concealment. My choice. The kydex holsters will retain their shape, not close at the top, will not run colors, and are impervious to chemicals. They work for me.
One caveat: I order loops for 1.5” and 1.25” belts. I find that the loops are a bit large, but I can live with it. The next size smaller are just slightly too small to fit on the belt (e.g., a 1.25” loop will jus barely not fit on a 1.5” belt). This could be cured by stretching, but I haven’t reached that point yet.
If you have any questions, either post them or PM me.
