Texhunter;
Both Sig and Glock are excellant firearms. I have experience as a dept. rangemaster, armour, gunsmith and competive shooter. I would give the nod to the glock based on the following. I am aware of the glock going 40,000 rounds without a breakage of a part and numerous other Glocks having 30,000 rounds or more without any part breaking. They have a excellant trigger pull and both brands are noted for good accuracy. I have had to work on several new Sigs that had sharp barrel channel corners and caused feeding faiures, but this is a minor problem easy fixed, and most Sigs did not have this problem. As for "limp wrist" failures, this is a problem with any semi-auto, not just Glock or Sig.
The bottom line, both are good firearms, try to shoot both and go with the one that is most comfortable for you and fits your hand the best. Either brand will do the job you need it to do.
