I was am a factory trained SIG armorer, have been for years...but sadly have had Glocks shoved so far down my throat I don't have a need for SIGs anymore. In my time as an armorer & when I COULD carry SIGs I can tell you I saw problems, same as any pistol maker. I carried the first 226 for a major west coast agency......jammed every shot. This was the first I heard of this "limp wristing" crap. This issue was a defective recoil spring; instant fix. Shot thousands through the gun until I moved on and sold it. Thousands through a 230, then carried a 220 and thousands through that. Never a single jam with either. HOWEVER, did witness a number of cops all start jamming on a hot afternoon after a day of shooting. This was where the limp wristing phenomena appeared, all with small guys and women..... I think this limp wristing thing takes way more blame than it can cause. Only other failure I saw was a uniform who got into a shootout with a bank robber......bad guy pulled a Browning hi-power, cop popped him with a hydroshock.....thru the elbow into the body with first shot, then gun misfired!!!! Badguy dropped, gun hand non-functional or the cop would be toast. Turns out he'd used the gun for YEARS and NEVER did any updates. Inside your grips are your "piano wire" looking springs, one of which returns the trigger........this broke. If you have a SIG, ALL your springs must be replaced on a maintenance cycle.....for us it was 5 years with about 5-7 thou thru a gun. If SIG isn't telling you this or you can't find it in print (I am out of the game and have been for a bit) then go find a police armorer locally and ask him. Springs are cheap, I used to be able to do a complete 226/220 in under 5 minutes. If you are not prepared to accept this type of maintenance buy something else.
If you have a malfunctioning SIG and don't want to pay shipping, try to find a police armorer and see if they'll help you. Glocks, SIGs, Berettas, etc., there is only so much that can go wrong and a basic armorer will likely figure it out.
Glockin' it cuz I have to...........
