Well I am going to start this out by saying this "Sig P229R, P229R... LOL" I Love that gun, I bought mine about 3 weeks ago and let me say this, Awesome shooting gun, very smooth and the trigger pull in the cocked position is GREAT. The first full pull is a little tricky to get used too, but you will. As for Sights, Mine has the standard non adjustable sights and I wouldnt want it any other way. My Glock 23 came with Adjustable, and I dont care for them, but I use it.
get the P229R Sig you wont regret it.
