All the modern Spanish 2" guns I've seen, with the standard 850 bar proof, seem to tip the scale at around 6#--which is, in most cases, a good half pound more than the weight of a Brit 2".
True Larry, but I had one at 5 3/4 lbs. I've also measured the width of the breach of standard Arrieta 12 bores and their 2" chambered guns. The 2 inchers are trimmer, only a sixteenth of an inch wider than their 16 bores. I've often thought of ordering a new one with 25" barrels and 14" stock. I'll bet they could bring it in at 5lb. 10 ozs.
