spring weight confusion

[DWowner]

Hi all,

I have an earlier DW Patriot commander, with the external extractor

I want to put a new spring in it. But my research, (spring sticky) created an ambuguity for me because I also read an earlier post. There is an earlier post with Dave S recommending a 16# spring, and there is the sticky thread saying they put 20# springs in the new ones they make today.

My question is, what was the original recoil spring weight?

thanks much in advance
