Re: Springfield XDm
Now that I think about it, the only thing I've heard complaints about is the round indicator on the top that protrudes if there's a round in the chamber. Personally, I like it, but it has a sharp edge on it that if you're going to carry it in a holster a lot, may damage the holster. You'd have to confirm if this really is an issue but something to think about from an LE perspective. As LE, I'm pretty confident you guys don't need a protruding bump to tell you there's a round in the chamber.
Also, no holsters that I can find on the market. But I found the SIG 229 holster fits just fine because they both have a large trigger guard. Hope that helps.
