"Limp-wristing" may well be a contributing factor to the op's malfunctioning experiences, but I am of the opinion that limp-wristing is an over-used reason for excusing a pistol that doesn't operate reliably. Personally, I don't want any pistol in my inventory that is sensitive to limp-wristing; especially one that is intended for self-defense use. I have plenty of pistols at my disposal, including several "Third Generation" Smiths, a couple of SIGs, a Beretta Model 92, an HK USP 40, a Ruger LCP, a CZ Model 85B and two 1911 variants that show no evidence of being susceptible to limp-wristing, no matter how loosely they are being held. Too many good ones out there to rely on one that requires a vise-like grip in order to function reliably imo.
