With the oddball Auto Ordnance barrel plugged into it, the Rock Island 1911 doesn't seem capable of a jam. It don't shoot all that great, maybe 4-5" at 25 yards; it's 0.577" muzzle is a poor match for the Rock's 0.583" bushing and it's upper lugs are not particularly well-executed. But it's allowed this pistol to chug through about 8 magazines of various .45 ammo without missing a lick.

I had my wife run a couple of mags through, it while I watched the ejection pattern. This wasn't much work because Peggi likes to shoot 1911's. The pistol was dropping empties in a two foot circle about six feet behind her and a bit to her right. I also caught this pic of the gun in full recoil, with a casing about 16" out of the ejection port.

I will be real glad to get my reamed OEM barrel, or a replacement, back in this pistol. I'm anxious to get it zeroed and start shooting some groups with it.

I'm looking forward to hearing about you getting the barrel back and installed.
