In Texas I tried to do something innovative. There's a lot of talk about trigger locks being on guns sold in the future. I support that. But I said if you want a trigger lock to make your gun safe, come and get one for free. So we're distributing in our State of Texas for free.
If you don't want a trigger for safety you can't get one for free. 
The context says "if you want a trigger lock to make your gun safe, come and get one for free" meaning if you don't want want one for gun safety you can't get a free one.
