Question about Springfield 1911A1 ILS and New MSH

[JohnMcD348]

I bought the BerryHill ILS spring set and used it to replace the internals with a S&A slimline Mag well Arched MSH. The parts appear to be pretty well fit for my 9132L. My question:

The BerryHill spring set didn't have the MSH pin retainer. Would the unit that is in the ILS set interchange or do I need to buy a different one. There is a definite difference in the length of the spring. I tired using the pin but didn't force the issue when I met quite a bit more resistance trying to push the Main Spring Cap back down.

Thanks

The retainer...the pointed plunger that fits into the bottom of the mainspring...is the same, assuming that it'll phsysically fit the spring tunnel in the housing.

Thanks Tuner. I'll put it in right now. One way or another.
