I always plan on some tweaking of the locks, I don't care who makes it.
You must lay out the relationship between lock and trigger set on paper. Very often I read about folks having the set triggers too far away from the sear bar, having to solder on a piece of metal. Or too close, having to bend the sear bar, or grinding the top of the sear bar down.
So often, the parts determine the stock shape. It's nice to have drawers and drawers full of parts to choose from. I have drawers full of stuff, but it's usually the wrong parts, so I have to buy more.
Remember, the set triggers can be reshaped, thinned down; bar bent to a different curve, etc. A lot you can do to make the trigs fit your style.
