Will a FNS-9/40 4” Barrel Function in a FNS-9/40C Pistol

I was wondering if a FNS-9/40 (FNX-9/40 same) 4” barrel would function in a FNS-9/40C pistol? If it does function can someone test with ammunition to see how well the pistol performs (reliability, accuracy, etc.)?

The regular fns9 barrel will physically fit into the compact. Here are a few differences.

You can see the difference on the nub that holds the recoil spring in place. But I think you would need a new smaller recoil spring assemble. I wouldn't try it.
