I've never owned a Glock, nor really been tempted, but watching gunTubers and reading reviews made me a fan of Shadow Systems. This and the fact that they are locally owned and manufactured here in the Dallas-Fort Worth area. It's amazing how light the MR920 is and how well it shoots. One of the biggest pluses is the feel in the hand; this is what traditionally kept me away from Glocks. The MR920 fits perfectly in my palm and has amazing grip treatment, tacky but not too much so. The real star of the show is the fitment; this is a tight gun manufactured to tight tolerances. I got a great deal from Bud's on my Combat model, a special run that was priced lower than the standard MR920 Combat because it has only a white dot front sight. This didn't bother me at all as I traditionally paint white dots hi-viz orange anyway. Everything else is exactly the same as on the regular Combat. The gun shipped in a really nice pistol bag in a cardboard box with the optics mounting accessories, Loctite a branded lock and two extra grip backstraps, a punchout tool if you want to remove the magwell and an extra mag. I couldn't be happier with the purchase and the shipping as Bud's got this processed within one business day and so I had it way sooner than expected.
