Like rikman said, any auto can jam and often it's not the gun's fault - too dry, bad mags, bad ammo, weak or improper grip, etc. Every time we qualify or train somebody's Glock, SIG, Beretta, S&W, or whatever jams for one reason or another, that's why we practice clearing jams/failures and getting back in the fight. The best you can do is buy a quality gun, test it to make sure that it runs properly with your chosen practice and carry ammo, and keep it clean, properly lubed, and well maintained. That will minimize the chances of having a problem. If you need more guarantee than that you should buy revolvers, a lot fewer things to go wrong.
I have number of guns that have never jammed or failed on me, both stock and custom, I would not hesitate to buy the Wilson and once I put some rounds through it to check accuracy and function I wouldn't lose sleep over whether or not it will work when I need it to.
