The attached picture shows my current (I continue to allow my experience to help define my wants and needs) belief in how a 1911 should be configured for me. YMMV.
It is basically a stainless Series '70 with the spur hammer replaced with a rowel hammer, a recontoured grip safety, higher profile sights, a serrated flat mainspring housing, a serrated front strap, new fire control components and action work to deliver a 4.5# trigger, the ejection port opened, a new bushing and barrel crown, a carry bevel, and Colt ivory grips.
The fitted bushing is tight enough for accuracy yet has been fitted to allow turning without a bushing wrench. The barrel crown was needed after test shooting showed groups larger than three inches at twenty-five yards even with the new bushing. The sights are plain black with no dots or tritium inserts. The rear sight is a Ted Yost interpretation of the Robar rear that reminds me very much of the factory rear on steroids.
It is the first one done of a pair. All work was done by John Harrison of Precision Gunworks.
