The shield feels really comfortable in my hands. I don't own one but a few of my shooting buddies do and I like em. Like Triple Chin said above, everybody will have a different opinion so if you like it, go for it. My wife has a glock 43 as a carry gun and I like it too.
You can get a shield for under 300 new so keep that in mind just in case you're not a 40 guy.
Edit: I carry in an alien gear holster. No complaints.
