Thanks for the reply. It may be me (I'm a new shooter), but my 24/7 shoots low, so I'd rather need something that adjusted for elevation than right or left. The sights are removable, so I was just wondering if there might be third party adjustable sights that would fit in the place of the factory sights.
I can, and have, learned to used the fixed sights to shoot effectively. This week at the range, out of 120 rounds shot at a B27Q half size target at 20 ft (eq. 40 feet with the full size target), only 4 shots were outside the 8 ring, and 100 of the 120 were 9 ring or better. I'm happy with that (well, I always seem to pull or flinch one or two shots out of thirty, and am not happy about that), but I have to use what is probably a bit of an unorthodox sight picture to achieve it.
