When I pull a trigger I try to do it with a steady pressure until it breaks. I try not know when it goes off but keep it on target until it fires. I want it to be a surprise when it fires. I will get the snap caps out and practice tonight. Try again tomorrow. One thing noticed about the Shield it is balanced, whereas the Sig is muzzle heavy which apparently I prefer. I am going to change the sights to I dot having shot both now I think I like the I dot on the Sig better.
