Apparently the stock sights, as well as factory replacements are 5.5 mm, while the ones from Angus are 6.5 mm, so one of those is on the way.
Put 400 rounds through it tonight, shot great. The new competition hammer produces a much better SA than the original one, a lot shorter reset. I had splits at 10yds down to .14. The gun is a bit snappier than the Tanfoglio, but I figure once the stainless guide rod shows up, that'll help a bit by making the gun heavier at the front. Definitely shoots high, and a bit left. I'm a bit perplexed by that as the sights are all dead center. I'm also ordering the other trigger (straighter) with the over travel screw. Once all that is installed, along with the new front sight, I'll check zero again. If it's still to the left, I'll move the rear sight a bit. it's not a huge deal, but enough to be annoying.
now I have to figure out a way to make a spacer to slip onto the Tanfoglio mags to remove the gap between the frame and the mag, I'm already beating up the mag catch holes on my Tan mags by inserting too hard on a slide lock reload. The mags go in too far and can actually jam, the factory mags don't do this of course, but they are those stupid 3/4 body mags. The base plates on them fall off as soon as they hit the floor. I'm gonna get Henning to measure his baseplates for the Tan small frame mags, if they are thicker at the lip area I'll just order some of his. I basically need the lips to be twice as thick.
loving the gun though.
