Negative. Let me elaborate. I have and old set of beat up STI gen 1 140mm mags with stock followers, springs, and base pads. The guts are not in the best of shape.

When the price of gen 2 mags came down recently, I bought four. I also have four new grams FKS-11 kits. My plan is to take the guts out of the new gen 2 mags, install the grams kits in them, and then use them as my match mags.

I was hoping that the brand new guts that came out of the gen 2 mags could be installed in the old gen 1 tubes to breath new life into them. They would make a good practice set.

I have four STI Gen 1 mags that all work great.
I swapped the followers for a gen 2 follower and none of them even come close to working. The dimensions on the Gen 2 followers are way wider. They won't even push up through the top. My feed lips are set at .380- .385.
