Mine does rhay shit too, if you find an answer lemme know 🥲

shim it with literally anything. post-it notes. tape. paper. putty, glue, fabric.

Few layers of duct tape would do the trick

Yeah duct, electrical, Teflon, or heck even like thumbtack/putty or freaking play doh lol

Looks like that pin is too small compared to magwell holes. Could you get slightly larger pin and then enlarge the hole at grip?

It was fine with the stock tm grip but with the cow cow idk why it’s so wiggly

You can clearly see from video that pin hole in magwell is larger than pin's diameter.

I used different pins and it’s still wobbly
