Funny looking part
Anyone recognize the mainspring housing on the left in these? Ostensibly both are 1911 parts, but I dunno...
A reader asked me and has asked other bloggers and fora. Everyone is stumped. So far. There is no hole for a retaining pin and that slot is weird, obviously.
I believe Auto-Ordnance used to inflict that on their mainspring housings. No one really knows why. However, some pistolsmiths have taken to drilling a small vent hole on the inside face of the mainspring housing to prevent a buildup of oil, grease, or any other fluid inside the housing from interfering with the compression of the mainspring and its cap.
I reserve the right to delete patently offensive comments. Or, really, any comment I feel like. Or I might leave a really juicy comment up for private ridicule. Also spammers.
You can always offend hippies in the comment section. Chances are, those will be held up as a proper example...

ReplyDeleteI had an Argentine 1911-ish pistol that had a mainspring housing much like that, IIRC.
