So wish me Luck! I got a phone line to a guy who went above and beyond the call of duty at SIG. Mark Hanson. I have been trying to make my SIGP220C3 work in D.A. For me in "the Gravest of extremes for about 10 months plus. I am no small man but my hands don't seem to realize that as they are short and Fat. I tried to buy a new P220C3 SAO But A. they only make a carry and Be it is railed. I am an older than dirt retired guy and refuse to change to an Operators type weapon I have no need of, I wait in my bedroom for the BG and know right where my door is. Ah But I digress if it can be done on my frame they are going to convert it for me to SAO. And wouldn't ya know it a week after I got my prepaid RMA a guy shows up on Gun Broker (Am I allowed to say that)? He's selling one with aluminum grips too for about $500 or so less than I have in mine with the SAO conversion and a thinner trigger I had installed which only gained me 1/8 inch. So I hope it can be converted.
