Good shooting times are ahead for Bud White.
Absolutely ditch the 2 piece guide rod.
As long as there is clearance for the ejector then the amount of space around it is pretty much just a cosmetic issue.
By the way folks check out the photo in the Member Picture Posts of Left Handed Bud banging off two .45s "Wild West Style" ~ It's a neat photo.
Actually, one of my tightest shooting 1911s has the most loose "slide to frame" fit & the barrel WILL move down slightly but, pop back up again when I press down on it & the gun is in battery.
As long as everything always "locks up" in the same place every time you should have a good, accurate pistol. Time will tell.
