Spikes Tactical ST9G

Any idea how to make a Spikes Tactical ST9G 9mm pistol lower California compliant ? Fixed mag route if possible. Thanks.

A Hogue freedom fighter installation would likely work.
I have done several of them on Aero EPC9 lowers which have a pretty similar magazine catch setup to the Spikes.

I'll have to check that out, thanks.

I do these installations if you are in the los angeles area.
The Hogue drilling jig won't work for any of the 9mm lowers so it takes a proper machinist to measure/locate where the holes get drilled/tapped so that the plunger will end in the correct location to stop the magazine catch from releasing while the upper is flat on the deck of the lower.
Beware that the magazine catch sits in a different place with a magazine installed than it does without a magazine so be sire to account for that as it will bite you if you drill the hole in the wrong place.
