shoots really low with couple types of regular 9mm ammo. would +P or +P+ make a difference? can't find these hotter loads locally for some reason or I would have tried. fixed sights, no aftermarket parts available. trigger sucks but LOVE the frame and slide. Any other ideas that would make it shoot low? I'm not a good shot but don't have to hold off with my other pistols at such close range. wish I would have been more into shooting when I bought it in 94.
