So I have one of the Caracal F Waffen works fixed sightsmodels. I cannot tell you how much I love this pistol. For the money there is absolutely nothing that can top it right now. My question for you guys is I am now going to be buying a Caracal C model. Should I stick with the fixed sight on the C or go with a QS model. Have any of you owned both types, and is it hard to adjust back and forth from each model? I think I would prefer the QS model cuz I really dig new innovative designs. Thanks ahead of time for any input!
