I'm looking at purchasing a 10mm handgun in one of the 2 flavors listed. I've handled the GLock G20 and it seems a bit bulky in the grip and I'm not a fan of the fixed sights. I've yet to handle a Springfield XDM but have heard that it is louder than most 10mm's but other than that it seems like a legit contender. Does anyone here own either of these handguns and what are your thoughts on them. If you're shooting something different in 10mm I'd like to hear your opinions as well.
