M&P 9 performed great in USPSA match [pics] Options

just talked to Dan, there was a misunderstanding by whats meant as a "factory contour" by Amidon... Long story short; they are still illegal..
we got a month and a half before stippling, any stippling, is allowed.

Interesting... just curious - what was the misunderstanding?
I had heard that USPSA was considering allowing grip stippling for Production in the 2008 rules refresh, but I haven't heard a final confirmation on this yet... so it's a done deal for 2008?

What type of mag holders are you using there?

They're CR Speed Versa-Pouches... a few of the vendors that support this site sell them - e.g. Speed Shooter Specialties, and i-SHOT

the definition of "factory contour" was the misunderstanding.
Moot point, though, cause stippling in 08 is a done deal.

For those interested in zeroing your sights at a given distance, here's the formula that I came up with for determining how much taller or shorter (in inches) your front sight has to be:

Gun Sight Radius * POI Delta
Target Distance (yds) * 36

Gun sight radius = the distance from the back of the rear sight to the back of the front sight, in inches
POI (Point of Impact) Delta = the distance that your average shot grouping is off from your POA (Point of Aim) --> Below POA is a negative number, above is a positive number
Target distance = distance from the muzzle to the target where you're attempting to establish your zero

So for me, my sight radius (with a Warren Tactical rear sight) was 6.5"... and my shot groupings averaged to about 3.5" high at 25 yards.
Therefore, (6.5*3.5) / 25*36 = .0253"... Now this number is added to the height of the current front sight (which for a stock M&P9 is .160") and there you have it!! In my case, I rounded down to the nearest thousandth and had Kenny build me a .185"er.

By the way, I subsequently found that this is pretty much the same formula that the Army Marksmanship Unit uses, so I think it's pretty trustworthy : )

Cool. Thanks XFactor!

Fantastic. I love formulars and maths 8)
