I changed my guantlet config because of this, i did not want big bulky guantlets, as the P1 was streamlined. so instead of the packing alot of people use , i managed to find someone who sold Latex gauntlet bottoms.
i then trimmed them down as much as i could and glued the resin tops on them, they fit extremely snug now and would not swing around even if i swung my arms around like a demented human windmill on speed.
just another option for you.
