Jeffrey, I have great success with searching the model plus gun parts list. Example : https://www.google.com/search?source=hp&ei=YRRTXruEOJKf_Qb0pL74Aw&q=gun+parts+list&oq=gun+parts+list&gs_l=psy-ab.3..0j0i22i30l9.2977.6655..7678...0.0..0.166.1201.11j4......0....1..gws-wiz.....6..0i362i308i154i357j0i131j0i10.JokkaTtolso&ved=0ahUKEwj7uIyO8-jnAhWST98KHXSSDz8Q4dUDCAc&uact=5
Are you talking about schematics? Schematics show a list and part numbers to firearms. I don't know what firearm you need it for but here is this one, as an example, in case this is the type of "gun map" you need: https://www.midwestgunworks.com/browning-buck-mark/parts.html
Jeffrey, schematics or diagrams can be found online - Example gun model + schematic/diagram = https://www.firearmsguide.com/index.php?option=com_content&view=article&id=1935:over-8-000-printable-gun-schematics-diagrams-and-blueprints-for-antique-and-modern-guns&catid=8&Itemid=167
Jeffrey, You can find exploded schematic views and parts list on just about any firearm online. If it is a gun you own almost all owners manuals have diagram and parts list in them.
