I believe you would have to purchase a gen 5 mos or g19 gen 5 with front serrations to get numbers 1 and 2. I think it's not possible to buy a g19 gen 5 with 1 and 2 without the front serrations. Otherwise I would have bought an fde g19, but I found out they didn't have the breechface cut.
Not sure about the country production specifics.
I was going to buy a FS g19 specifically to get this so called much better ejection. I ended up ordering a g19 mos becausemmi want to try the red dot concept.
As soon ask get mine I'm going to try the 1911 extraction test to see what happens. None of my gen 3 or 4s can do this but I don't have the apex fre just 30724 ejector.
Also does anyone happen to know the rear sight dimensions from the top of slide to top of rear sight?
I know the factory height is .256" overall.
I'm excited to try the red dots. Is the holosun 507c still a solid optioon to try the reds? I also noticed a deal on Dawson precision with sights and deltapoint pro for $450.
I'm not trying to spend rmr2 or Aimpoint micro money if the rds doesn't shake out.
