A while ago I did some testing on the recoil springs.
Three springs used.
Stock 9mm, high speed 9mm, high speed 45acp.
All cycled fine.
Not really that much difference in accuracy.
Charging handle pull was noticeably different.
High speed 45acp was much harder to pull back.
In the testing, I didn't check to see if the bolt went all the way back to hit the buffer.
Should have done it, but I forgot.
Now if all three springs cycle the action.
I'm thinking the bolt might be hitting the buffer on all three.
Wouldn't it be better to keep the 45acp spring in it to save the buffer????
I'd rather have the high speed 9mm spring, because of the charging.
