ERMA M1 CARBINE OPERATING SLIDE / ERMA .22LR M1 CARBINE & IVER JOHNSON M1
This slide is far superior than the one made by Erma. It is made from high grade aircraft alluminium, CNC machined one at a time, therefore much stronger than the original.
It is hard black anodized which is like a Teflon coating. This should stop wear and tear to both the gun and slide.
