Hey all. I'm brand new to the forum here and this is my first post. As such I hope I'm not about to ask something that's been asked a bunch of times, and hopefully I don't make myself sound like an idiot. 
Anyways, I recently purchased my second handgun. As you may have guessed, given the forum, it is a Sigma. SW9VE to be exact. I bought the firearm used from a local Gander Mountain.
I had the opportunity to take it out to the range last week for the first time and I wasn't overly excited with the results. First and foremost, I found it to be decently accurate, and the trigger does not bother me in the slightest. However the continuous combination of jams and stovepipes drove me crazy. I even allowed a couple of my friends to try, and they came across the same problems.
I immediately went back to Gander and spoke to their gunsmith and he said that he believed the cause of my woes was in fact limp wristing as opposed to anything mechanical on the firearm.
Now I'm not exactly experienced when it comes to handguns, and I intend to head back out to the range ASAP to try to eliminate the problem. However I was reading a few opinions online that seem to think that limp wristing is a problem that's been blown out of proportion, and that stovepiping is more related to weak extractor springs or otherwise damaged parts.
Also since it may be important, I have never had any limp wristing issues with any of the other handguns I have fired. However these other handguns have been unanimously 45 caliber and larger frames. It occurs to me however, that the sigma, being a polymer frame, recoil operated, 9mm would be about the most susceptible to limp wristing of everything I have fired.
So my question is, I'm sure the sigma has found its way into plenty of novices hands, being a relatively inexpensive firearm, have any of you had any problems with limp wristing causing failures? Any one out there with a proven reliable example, can you cause these type of issues by intentionally limp wristing? For those with more technical knowledge, do you think my problem is limp wristing or should I look into trying to replace some of the ejection related parts? Any way I can test to see if parts are overly worn out?
Wow I wrote a novel. Either way if any one can shed any light or help me out it would be greatly appreciated.
