Interesting. I have the same problem with my T-series Browning HP- seems to shoot a few inches low with 124gn @ 12 yds. I'm not consistent enough with it yet to make a meaningful check at 25 yds., which I read somewhere is where it's zeroed for. I've thought of replacing the tiny military sights with larger ones. Even the fixed ones from Browning might allow me to make a little adjustment with a file. Don't really want to spring for adj. ones, though, esp. as there's the added cost of getting a gunsmith to mill a dovetail for a new front sight since the orig. is silver-soldered in, like a mil-spec 1911.
