looks like you are planning on inventing a bicycle. make that re-inventing. this has been done some many times. not to say you shouldn't do it, just maybe help us understand what are you envisioning for your 9mm carbine. How will it be different from all other 9mm carbines. your idea/goal can have merit, but most likely already has been designed and implemented and we can advice/spare you some time and/or frustration. but if you are doing it just for the heck of doing it, then props to you, making/designing guns is fun and is truly american pass-time and totally fun thing to do. i'm with you on that.
as for weight of the bolt - it's not as crucial to get it exact same as sten. i can tell you that bolt in ANY blowback sub gun needs to be in the ballpark of 1 pound or so (depending on the caliber). but you still will need to play around with return spring pressures to get it cycle reliably AND smoothly. my PPSh-41 bolt weighs 14oz (400 grams) glock frame will be roughly half that.
as for glock receiver weight it's very light. assuming by receiver you mean frame. glock frame is made of nylon and weighs just a few ounces - very light compare to steel framed pistols.
judging from your questions, however, you might be interested not in glock receiver/frame weight, but rather in weight of a slide. it's to say, significantly more than the frame, but still fair amount lighter than sub-gun's bolt.
moreover glock is a locked breech design, meaning that chamber is mechanical locked/sealed during firing, while with sten (or any other sub-gun) breech is not sealed and bolt is free to move backwards during firing. only reason it doesn't blow into shooter's face is a combination of bolt's heavy weight + spring that hold breach sealed long enough for bullet to leave the barrel and for chamber pressure drop to a safe level. Level that is sufficient only to cycle said firearm (extract spent case and reload new round) and not embed bolt in shooters face.
most of 9mm (and other high pressure handgun rounds .40s&w, 10mm, .45acp) use locked breech design.
low pressure handgun rounds i.e. .380acp, .32acp, 9x18 Makarov can be safely chambered in handguns w/o locked breach - i.e. blowback operated.
only exception being is Hi-point C9 that is only handgun that i know of currently produced that fires 9x19 and is blowback operated. however slide on that gun weighs over a pound, something in the viscinity of 17-18oz
