Well, I'm not in any way an expert on the internal workings of a pistol. I bought my CD ECS back in April and have been very pleased with it so far. However, the last two times I've taken it to the range, I've experienced what I would call a "fail to eject", meaning that an empty cartridge did not completely eject and wouldn't allow a new cartridge to chamber. It has happened three times now, after about 30-40 rounds through. I smashed my wrist a few years ago, causing some tendon and ligament damage, and have quite a bit of arthritis in it, so I suspect that I may not be getting as good a grip on the weapon as I should be, which is causing the problem. Any ideas?
