PRod Custom Magazines. Anyone Make Them?

Looking for custom Prod mags or factory mags that have been Improved to feed better.

The factory one works OK but thinking a custom would perform better and feed more smoothly.

Not too concerned about price just super smooth feeding.

Maybe they can be modified with different parts to achieve the same outcome.

If I need to purchase a very small quantity, would consider that option also.

Tried a search but nothing showed up.

Any help or suggestions will be greatly appreciated. 

Thank you.

The factory magazines are OK but seem ruff when operated. Have some FX guns and their magazines are easy and smooth. Hopping someone made an aftermarket replacement with an improvement in their function. Seems like the pellets engage some resistance passing through the magazine. It is a little difficult putting into words. I have several of the factory mags and they all have this issue. The problem is not a deal breaker just a little annoying. Fishinwrench, thank you for your reply. Maybe the problem is my custom Prod?
