I'm probably going to purchase an Advantage Arms .22 conversion kit for my Springfield GI.45 Champion. However, I am a little wary of their recommendation to exchange the original mainspring for one with reduced power (23# vs. 18#). (Their website actually refers to the mainspring as a hammer spring).
I've reviewed the procedure to change out the mainspring, and it doesn't look too difficult. However, I don't want to take disassemble the mainspring housing everytime that I swap the .45 for the .22 and vice versa.
Two related questions:
1. How would an 18# mainspring affect the function of the firearm when firing .45 loads?
2. Aside from Advanatage's statement about reliability, does anyone have any practical experience using the original mainspring with the conversion?
Per AA:
Does anyone know if the above statement holds water?
Thanks!

Per AA:
Our newest 1911 kits work pretty good with the factory 23 pound spring. Using an 18 pound spring with 45 rounds does not affect the gun. Most serious shooters switch over to the 18 pound spring in their 45's.
Does anyone know if the above statement holds water?
Thanks!
