Most useful general reference in that area is I suggest The Custom Government Model Pistol by Simpson, Layne Published by Wolfe Pub Co, 1992 ISBN 10: 1879356163ISBN 13: 9781879356160 which went through two editions. He found that conversions one step each way tended to work that is a 10mm conversion from a .45 tended to work. Dated but from a time of exploration and custom means custom not a poorly chosen sales term meaning high grade. Brownell's will sell you anything you need. For a while the hot tip was blems on clearance google 1911 slide blem/blemished and there are plenty of hits but the market has changed. Generally if Brownell's doesn't sell it you don't need it but Brownell's does require minimum sales figures to be listed so truly specialty items will come in, saturate the market and disappear from the Brownell's catalog.
