Mag insertion is not consistent. I am left handed. Not my fault . To fully insert mag, with pistol in my left hand, sometimes I have to press mag away from me to fully insert mag.

It bears notice that I have had some failure to extract issues, especially with standard velocity. I just installed a Tandemcross extractor, and will see if I get the same behavior. (The stock stamped piece did not appear to have this issue.) I ..read more
