MR. DAHERMIT
You can believe what you want to, but the recoil springs are not interchangeable with each other. The government model, commander, & officer models do not use the same recoil spring. Yes, the compression weight ratings may be similar, but the overall length is not the same.
Example: The gov. Model spring is 5.750" in length.
The commander model recoil spring is 5.125" in length.
If you still think i am wrong, then you need to take this up with bill wilson, john nowlin, ed brown, or walter wolff.
I rest my case.
