There are plenty of new and rather naive gun owners that say, "I have kids, I need a safety" and plenty of them think the lock is a great idea.
Most seasoned firearms enthusiast have no use for it. Most, like some here, tend to ignore it.
I just think it's ugly having a big grey hole on the side of the frame for a device I'll never use.
Removing a sideplate and dumping the lock parts is a simple job.
Some people have no mechanical aptitude and probably shouldn't try, but it's always obvious by tool marks, buggered screws, and the sideplate seam being peened over.
There's plenty of people that seem to think that being able to disassemble a gun qualifies them to be able do action work...and I just tend to avoid such guns.
