MPBR really isn't intended for .45's pistols, it's more suited for long guns. You can answer your question yourself, how well can you shoot at 25 yards? Then try again at 50 yards, I'm sure you will find how well you group some where in between those two distances. Good luck.
The information I'm looking for is how the factory sets up their fixed sights, independant of any error that I will surely add.
My title should have not included the word "Maximum". What I am interested in is my pistols factory "Point Blank Range".
Check out the following link, it lists the MPBR for handguns assuming
a 6 inch target.
To maximize the .45 ACP's Point Blank Range, it suggests that POI be
at +2.6" for a direct POA at 25 yds. The MPBR for the .45 ACP would
be 88 yrds. e.g During the 88 yrds, the bullet would not be greater
than 3" above or below the POA.
The gunshop I bought my Kimber from said that for the fullsize guns, they are set up to be POA/POI at 25 yards. The dealer demonstrated this for me with my gun, as my proficency was lacking at that time.
I shot my Desert Warrior for the first time this last weekend.
I put 100 rounds through it. I had 1 FTF. When I pulled the
slide back, the mag released. I refitted the mag, and didn't
have another problem.
I was shooting about 3" low and 2" left at about 7 yrds.
I have only shot a few rounds of other peoples pistols in the
past, so I'm basically a newbie. I plan on putting another
100 rounds in this Thursday.
At this point, I'm assuming the issues are with me. As I shot
more, I'm hoping I will work it out.
