We’re sorry to hear they did not perform as expected. Our nipples are precision-machined on high-quality CNC equipment to exact tolerances. The most likely cause is the quality or age of the caps being used, as we have encountered similar issues with older CCI No. 11 caps. We recommend trying a fresh supply of caps. Other possible causes include excessive cylinder-to-barrel clearance or a hammer spring that is too light, although older caps are the most likely source of the problem.
