Part of the beauty of the 1911 is that it can be detail stripped without tools, as long as you have slotted grip screws, a GI style recoil spring guide and plug, and an internal extractor. Grip screws, and the spring guide & plug can be put into almost any standard 5" 1911. External extractors, however, are there to stay, and there is no standard for them. Every manufacturer has their own proprietary external extractor designs. Internal extractors are standardized, and they just require minor fitting & tuning to install. I also don't care for firing pin blocks; I've had one break and render the gun inoperable.
That would leave me looking at a new Kimber Warrior or SIS, used pre series II Kimber, new or used Springfield, new Colt 70 series repro, used pre 80 series used Colt, new or used 80 series or later Colt with FP block system removed, or one of the newer Dan Wessons with internal extractor.
Of those, any in a 5" gun could be configured with a GI guide & plug. When we get shorter than 5" only Colt and DW offer internal extractor guns with true commander 4.25" length barrels which have a conventional bushing. This conventional bushing allows for the GI style guide & plug. The DW is ready for those parts to drop in, but on a new Colt I'd remove the FP block mechanism first.
