As both a Glock and Sig armorer I have mixed feelings. The Sig is a great gun no doubt about it. The drawback is it is twice the cost with twice the parts. I could teach a monkey to strip a Glock not a Sig. It's hard to screw up a Glock, there is one piece in a Sig that if put in wrong turns the gun into a single shot pistol until it is returned to the factory. The Glock is a much easier gun to train the average person on.
