Yes that much pressure can do a lot of damage. Have your smith check the lower lug and link thoroughly. Look for cracks in both especially at the point the lugs join the barrel. If the blow out was big enough you could also have possibly sprung the frame and slide, damaged the rails, slide stop,extractor,ejector, top lugs. Any or all. Best to have it completely checked out before you do much with it. If you shear the lower lugs its a nasty SOB to get the gun apart without causing more damage.
