1911 Mainspring Housing Hole Size

[deltaenterprizes]

I bought a Kolimous, not sure of the spelling, checkered mainspring housing with an attached mag funnel off EBay and the hole for the spring and plungers was too small!

I started to just enlarge the hole bit it is a really odd size!

The workmanship on this part is beautiful!

To return it I just downloaded a post paid label and got a refund in less than 24 hours!

Welcome to the world of aftermarket 1911 parts. I bought a mainspring housing that was too small to use the Colt spring and plunger. I just bought a new spring and plunger from the maker of the housing and everything went together just fine. While I was at it, I went to a 19 lb mainspring. Drops the trigger pull down some and will still pop every primer known to mankind.

This one came with the spring and it did not fit!

Well, if their spring won't fit their mainspring housing, I would say they have a quality control issue.

Drill ream and polish in the shop for fastest ignition.

I agree!

I was thinking about doing that but the odd sized reamer would cost almost as much as the part!

It was easier to print a postpaid label and return the defective part and order another one!
