Best Practice/Dummy rds for HK 53?

[HK53King]

Yet another hope not too silly inquiry...
For reloading and dry fire practice drills, what type of inert dummy/snap caps is best to use? They have several different brands/types, aluminum and plastic designs come to mind...
Thank you guys as always for sharing your knowledge.

The Aluminum A-Zoom snap caps are the best..

No silly questions here--- I would probably agree with @Hk-USPC-40.
