thank you, GR.
here's a closer photo of the front sight. it also shows the custom made Belt Mt base pin (but this was also taken before the crescent ejector was installed):
there's a world of difference between that polished spherical front sight and this square sharp edge version. day and night. i just use a black Sharpie to fill in the serrations now and then. i also used the Sharpie around the rear groove. helps a lot.
when i first got it and test fired it, even on an overcast day the front sight lit up like a mirror, making it impossible to shoot with any consistency. add a crappy trigger and shooting left 6" at 50 feet, my shots were all over the place.
but since all the works been done, although i haven't papered it, i have no problems getting dead-on fist-size groups at 50'.
like you indicated, i have a 12" x 14" steel plate at 70 yds and can hit it all day long. good enough for my needs.
(fyi - my carry load is a 265 gr WFNGC on top of 8.5 unique)
