Testing and Tuning group.

We warmly invite you to share your real-world experiences right here—whether you’re testing slugs made with GMI kits or any other tooling on the market.

•  If the results are excellent → it’s another proud feather in our cap

•  If something doesn’t perform as expected → it’s a valuable lesson that helps us improve fast

•  If you have a suggestion or idea → we’ll seriously evaluate it and implement whatever is practical

•  If you see any way we (or the wider slug-making community) can do things better → you’re in exactly the right place to speak up

At GMI we have a simple principle - Honesty is the best policy - We take criticism like champions, So feel free.

GMI Engineering Testing Forum

This forum is exclusively created for the GMI Engineering Testing Team — a space where members can share their technical insights, testing results, and hands-on experiences with GMI products.

Our goal is to build a collaborative environment where:

• Team members can document real-world performance and testing feedback.

• Users and engineers can ask questions, exchange ideas, and troubleshoot together.

• Everyone contributes to improving the precision, reliability, and overall performance of GMI products.

All participants are encouraged to post their findings, share observations, and help one another get the best out of GMI Engineering’s precision systems.

Your expertise drives innovation — let’s refine precision together.
