JOB.SPILBORCBS Custom Extended Auto c c When master nzachinist John Spilborghs decided to go into customizing .45 $) he didn't realize he would soori be turning out a patented longslide that looks great and wins matches By Kevin Steele JOHN SPILBORGHS IS A METAL craftsman of the old school. A native of Belgium,. he came to the U.S. fourteen years ago and set up business as a machinist and gunsmith in Santa Barbara, California. Becoming interested in IPSC shooting several years ago, John drew upon his machining talents and wealth of original ideas to create an extended .45 that was both unique in design and an improvement over the existing methods used to make long barrel auto pistols. Beginning with a 6" Bar-Sto barrel he expertly fits the barrel to the slide, making (Continued on page 83) Cut in barrel locks into sight extension when barrel returns to battery. 82 AMERI.CAN HANDGUNNER· JULYIAUGUST 1981
sure that the barrel lugs mate perfectly with the cuts in the slide. The next step in the conversion is perhaps the most important, and in Spilborghs' case the most innovative. Since John is a machinist, he decided that his extended .45 would feature a custom designed bushing (currently patent pending) that would secure the slide and at the same time increase the sight radius. We should digress at this point to mention that most extended .45's today feature an extended slide. This is accomplished by either casting a longer slide to begin with, or welding sections of two separate slides together. Spilborghs opted for neither, instead an extended bushing was conceived that is milled and turned from a solid piece of bar stock. As John says, "Welding is welding, you have to take advantage ofyour talents; I'm good on a machine~' The extended bushing is carefully fitted to the gun in a manner that makes it look as ifit's always belonged there. Two lugs on the bottom of the bushing lock it to the slide. The recoil spring plug is grooved to index with the forward face of the bushing lugs. The recoil spring guide is extended to meet the plug, and it is buffer~d to take up recoil shock. The end product stabilizes the barrel to the extent that under one-inch groups can be obtained from the Ransom Rest. Custom Pistols J.
