Nice 4506. Adj sights are great for a shooter. Trijicon makes, just like revolvers,. night sights for them. The gold, hey, you bought it that way, not a deal breaker for me, as long as everything works. It may be good for some fun at the local gun club. Not like it ruins any value or collectability. If someone doesn't like it, its easily changed.
But I would say, I probably would never carry it as a defense gun, just could lend to some the idea that you might "want to be" a bit gangsta. There are all kinds of guns with gold accruements. I have a High Standard, a Browning and some others I think.
Try the straightback grips 20-25 usually, feels better to most people.
