You can use M4x25 bolts and nuts as a substitute for fcg pins if your lower will fit anti walk pins. There’s a remix of the fgc 9 that should have it since the original fgc9 lower doesn’t have enough room for the nut.

Just using a standard mil spec trigger, used to be using the csgcg but never worked with the cnc bolt.

I made a new lower that is grip integrated, but I won’t be uploading it soon due to it being poly modeled. One thing I noticed about the safety detent is that the hole is either misaligned on accident or purposely.

Many times when drilling the detent hole do I accidentally bust a hole on the side wall making the detent not so snappy
