I'm new to 1911's and definitely not a pureist. I recently aquired a new in box S & W 9mm pro series. I like it. Just made my first trip to the range with it. I did clean it first. I initially had thin gloves on and discovered that when I changed my grip sometimes the hammer would fall and I would have a failure to fire. I played with it for a couple hundred rounds and discovered that if I did not grip it properly( not tight enough) The hammer would fall but not fire. When I got home I tried various things with the old pencil trick and confirmed it is a grip safety issue. If it is not fully pressed sometimes you can get the hammer to fall without fireing pin contact. I think normal operation is the trigger should not break and the pin should not fall. The gloves were a big part of the problem, but it did happen twice without them. Anyone have anything to say on this issue. I thought I would ask here first before I call S & W. Thanks in advance for your imput.
