Back in December of 2010 I had the privilege of being invited to Gunsite for the introduction of several new Ruger products, among them the Ruger Gunsite Scout Rifle, which I have reviewed previously. Also present at the gunwriters' review was Ruger's then-secret SR1911, which we've been keeping quiet since. I personally am not a 1911 aficionado. I like the design and have owned several, but I'm not as familiar with the platform as some. One hundred years after its adoption by the U.S. Government as a military service sidearm, Ruger is now offering their version of John Moses Browning's classic pistol. The 1911 type has been produced in many configurations by many manufacturers in numerous countries. Some companies currently producing the 1911 use parts imported from foreign countries, whereas Ruger's new SR1911 is wholly American-made. Every pin, spring, screw, and part is produced domestically in the United States of America. The pistol is built on a 1911A1-styled frame, including crescent relief cuts on the frame behind the trigger, though it departs from the -A1 with a flat mainspring housing and a lowered and flared ejection port. Pistol specs: Manufacture: Sturm, Ruger & Co Model: SR1911 Caliber: .45ACP Capacity: 7 or 8 rounds Barrel: 5 inches (mfr) Weight: 36.4 oz (w/o mag) Trigger pull: 5 lbs 7.0 oz (tested) Grooves: 6 Twist: 1/16 right hand We were amply provisioned for testing. Seen here are four .50-caliber cans of preloaded 7-round magazines. Because the only thing better than shooting is having somebody else load the mags. ...we ran out anyway. Ruger brought several more cases of .45ACP but after we burned through the initial lot of preloaded magazines we had to reload our own. On the range with the SR1911. We shot in two alternating groups. We also shot in low light... ...and later in full dark with flashlights. This range session yielded no usable pictures.
