Hi guys. I installed a Yodave shim and spring on my 452 and it passed the bump test and worked perfectly with snap caps. I went to the range today and started off fine, but after a few shots it started to not reset the trigger every once in a while and I would had the cycle it a few times to get the trigger to reset. I haven't messed with it yet, but does anyone know if it is the shim, or the spring, or both that would cause this? I currently have the smallest shim and the second lighted spring installed. Thanks
