OK... I have owned a G20 for several years. I bought it in 2004 as a factory Refurb with NS because I thought it was a great deal and that I could use it hunting. While the sights are OK, I didn't find them to be what I really wanted in a hunting pistol, but rather than pull off the night sights, I left them on and carred it with me as it was. Flash forward to now.... Last Sunday, I closed a great deal on a LNIB G20 with standard sights (how great a deal? $400 for the pistol, red-label box & accessories, 2 mags and 15rds HydraShok to boot). I am now interested in building this to be that hunting 10mm that I really wanted. I am considering a 6in aftermarket barrel for it and some finer sights (possibly adjustable). What would the group recommend? TIA.
