I've not paid a lot of attention to weapons over the last 10-12 years (I admit)...that must be a heavy gun to accomodate 7 in .44.
I bought some cleaning supplies today and handled (ohhh, la, la!) a SIG in .40 and the Baretta 92F side by side. The SIG was noticably heavier, though smaller in size. Can only speculate what the weight would be with loaded clips--but substantial.
Most local gun shops are small, so it was nice to find two nice guns side by side.
