I have this gun, as well as the 9mm and .40 version. Hands down, in my opinion, the best "feeling" pistol I have ever owned. Not a hickup yet, and I have put well over 2000 rounds plus through each of them.
While I personally dont like Glocks and would'nt buy one, it's just a personal preference thing to me. They are damn reliable, and this "jamming" up thing, well-this is the first place I have EVER heard anything like that, and my dad owns a couple of Glocks and hasnt had any problems with his.
I carry the SIG P229 .40 at work (USCG Law Enforcement), and its a nice piece as well, and we have'nt had any problems with it in the USCG that I've heard of....
