My son has proven the Sigma he has in .40 S & W is surprisingly accurate considering the dreadful double action trigger pull.
It has also had THREE out-of-battery-discharges and has him quite snake-bit about .40 S & W. In every case there was no personal injury, and only once was the gun damaged beyond expulsion of the magazine. (Extractor was lost.) It's a tough gun! Very good ergonomic feel..points well.. In every case the gun was repaired and updated free by S & W.
Group: What are your thoughts on the wisdom of putting a stronger recoil spring from Wolff to reduce out of battery discharges?
