Isn't that a Sig thing?
Seriously, why are we talking about this? Mr. Gaston is an engineer, he did a risky move back in the late 70's, early 80's and it paid off.
Why do so many le agencies carry Gee Locks you ask? Money. But that's just my opinion. I assume their prices are hard to beat once an agency puts out a bid.
Anyway, I don't think the pistols challenge each other. What's perfect for one might be terrible for another (i.e. grip, trigger, sights, etc). Really no point in arguing about.
I think we as shooter (should?) challenge each other. A good shot will outshoot me with a terrible gun, period. So.... it's not the gun. It's talent, skills, years of consistent practice and real life experience!
