My current everyday carry around humans is a SigSauer P365xl, it has been a trusted and reliable piece of gear. Recently my son, aged 50, has decided that he will take the classes and start carrying. I am thinking of giving him my Sig and going to a hellcat. Since there are tons of young grandchildren running around I am a bit worried and would like a manual safety. Is that a possibiliTy on the Hellcat? Also if I go with the threaded barrel and use a compensator do I need a different set of springs like I had to replace on the Sig?
