can it be done? i don't really want to answer that. it involves unorthodox procedures,real safety issues,possible parts breakage issues,press check issues and i'm sure a few more issues i'm not thinking of at the moment.
you don't have a decocker. that means your not going to chamber a round from the magazine as normal procedure. I don't even think you can hold the slide back to manually insert a round in the chamber because it would then be in SA. the procedure your thinking of is highly unorthodox and even dangerous.
how are you thinking of doing it? how is the case rim getting over the extractor? does it involve the disassembled gun with a 9mm round as one of the parts your putting together? does it involve pulling the trigger? i know that you can do it,so can i,...but don't.
there's no way i would ever recommend(or teach) this no matter how your thinking of doing it. honestly,it's not even practical on a daily basis. did you not know this when you bought the gun?
Hunter2011,please don't take offense. either use the gun as properly intended or sell it. believe me,there's nothing unusual about changing your mind and selling a gun. people do it all the time. perhaps you'd prefer a S&W CS9 Chief Special 9mm or one of the other single stack older S&W. almost all of the pistols of this size,weight and slimness are DAO or have a glock-like trigger,believe me I've looked. the choices in DA in this category are super slim pickings. my eventual conclusions have taught and proven to me that i prefer a full size gun for the realities of what can happen in a SD situation and with the proper holster and belt it works perfect and is my preferred method but that's besides the point.
good luck to you.
