I had an XD 4" in 357 Sig. Wow. what a handful!! This gun got the attention of everyone on the shooting line at the range. My handload was 10 grains of Blue Dot, 124 grain plated flat point, a Winchester primer in a Remington case. Talk about muzzle flash! I cannot imagine using this gun in a defensive situation especially in the dark! It would have to be blinding (and brutally loud) Overall, the gun was flawless for 1000 rounds or so I put through, but no where near as accurate as my Taurus PT99 9mm or Rock Island Armory 1911 45, with handloads or factory stuff. That is why I don't have it anymore. However, I loved the way it felt in my hand and would someday like to have one with the 5" barrel in .45 Auto.
