Few questions for 1911 mechanics: Dropped in a C&S Tactical trigger kit into a PT1911. On testing I decide to check trigger reset: I cock the hammer (directly or with slide), trigger fire it (it feels fine), and hold the trigger back. While holding the trigger back, I discover it is very hard to rack the slide, unless I let the trigger out. 1) Is this relevant to the function of the gun? 2) If so, what is causing it? I've taken the upper off and compared the mechanical behavior of the various components at the top rear of the frame with my other 1911's (all series 80 style), and I do not see a difference when the trigger is held back on the other frames.
