I recently bought a G26 used with a broken plastic slide, I heard that the HFC G26 slide works on the gun so I ordered that to replace the busted stock one. It fits on the gun fine but the gun won't cycle, it will go all the way back but won't come back forward or it just comes back part way. There are 3 positions where it seems to get stuck (photos attached). Part of the front of the slide seemed to be pushing on the plastic so I grinded it down a bit but it still gets stuck when returning to regular position. Anyone know what else could be catching it or what I should grind down to make it return properly?
