1991A1 Main Spring

[Chesster]

I have a new steel checkered mainspring housing along with 23# and 19# springs. I will be installing one this week. Which, in the expert opinions here, is the best main spring to use on this for a carry gun???

Well I am far from an expert but I would run the 23 pound mainspring.

If the hammer & sear are set up properly, you can get a very nice trigger pull with the stock 23lb spring.

+1, 23 lbs is the way to go.
