I have the compact XDM in .45. It has the 3.8" barrel. I bought it for general shooting and concealed carry. Even with iron sights, this compact is a good shooter, better than my meager abilities. I've only put about 300 rounds through it. All with no trouble. I ended up changing backstraps to make it more comfortable in my hand, though.
You also get a lot of stuff with the pistol. Among these are a hard case, three backstraps, a magazine loader, magazine grip extensions, a RH holster, a 9 round magazine and a 13 round mag. But don't be swayed by "free" stuff. I don't care much for the holster or mag loader. Better than nothing I guess. You'll be getting your own holster and Maglula has better mag loaders.
I think the compact is a little big for easy concealment in summer clothes, but a lot of guys have no trouble doing so and carry daily.
If I buy another pistol in .45, it'll have adjustable sights for more serious target shooting, maybe the XDM 5.25 in .45. I think it's a good product.
The big criticism you'll hear is that the striker retaining pin will work its way up or crack if you dry fire a lot. I talked to Springfield about this, and their rep said it only happened with thousands of rounds of dryfire with no snap cap. BTW, the weapon will still fire even if the pin cracks. Powder River Precision makes rolled pins that are really tough, and some XDM users put them in. I've done around 1000 rounds of dry fire with no trouble. But I use a homemade snap cap. XDMTalk has forums with good info on these products.
