All the recent talk about about Berettas reminded me I have an Inox Storm F type. One of the things I've always liked a lot about the Storm is that it has a really good DA trigger out of the box, but like everything it could be better. Factory pull measured around 12-13 pounds in DA and just over 5 in SA.
I forget where I saw it, but it was suggested that the D mainspring from a Cougar would work in the Storm. You have to use the Cougar springs because the Storms all use the same hammer/mainspring regardless of model type. Brownells had a bunch of Cougar D springs, so I bought five, got some help on how to remove the factory spring and then went to work.
The end result was pretty spectacular. The DA trigger pull is now under 10lbs and the SA is right at 4. The gun was 100% at cracking primers! even with the lighter mainspring installed. I had some Winchester NATO stuff that it set off no problem. So far, I'm really liking this gun, I just wish it wasn't so friggin' huge.
