So is the 1911 and a large percent of many guns are old browning designs still being pumped out.
The difference is like 90% of the 1911s being sold today at least they bothered to modernize them- FAR better sights, better safety levers, front strap checkering, flat MSH, etc. Most of the BHPs you see, outside of the rare custom job, are basically the same pile of mediocrity that existed back when the model was introduced.
