calling the GT 1911 braintrust.... I went to the range earlier to try out some new Tripp Cobra's I just got and ran into a couple of problems.... the details: 5" RIA Tactical; WWB & CCI Lawman 230gr FMJ; Tripp Cobra 8rd mags w/plastic baseplates. now the problems: first, the rounds were nosediving into the feedramp..... using the slide release to chamber the round and manually racking the slide both gave me the same results.... I removed the first round from the mags and the were still nosediving but would then slide into battery.... second, and more disturbing to me, the slide was locking open on every single round fired.... I tried altering my grip and it was still happening so I'm 100% sure it wasn't grip.... when I modified my grip to pin the slide release down with my thumb the slide would cycle fine.... the mags fed, but still were hitting the feedramp and "bumping" into the barrel.... also, I've ran a few hundred rounds through the gun with CMC Shooting Star's & the factory RIA mag with zero issues.... I had the CMC's with me and the were flawless.... any ideas?
