Replacing the bbl can help(at least can use lead). Might even try a Ghost 3.5 lb trigger unless this is your duty weapon. This is a .40 I assume from your original post. They are not condusive to most accurate cals, one of reasons dont see too many in the PPC disciplines. Never say never. Hope it works out for you no matter, and interested in results.
What loads do you intend to try @ 50?
