UM Tactical UM3 mount & Holster combo + M&P9 + Apex CAEK kit (WARNING - Pic Heavy)
So, after installing the Apex CAEK kit and polish the internal contact points to a mirror finish, my M&P trigger has a consistent crisp 2.75 lb trigger pull with a loud click reset. Black out the rear sight with Dykem marker to help achieve faster target acquisition. Still, I wanted more, like an optic...
But the M&P C.O.R.E will cost me another $1000~
I searched, and look around and finally decided to sunk in $600 to get the UM Tactical UM3 mount & Holster combo and a Burris Fastfire 3 for my M&P9. After testing the system at the range and I have the following to share with your fellow gun nuts.
PRO:
-One mount fits all pistol with a 1913 pic rail.
-Tool less installation in less than 30 seconds between pistols. Mount and optic can also removed in less than 15 seconds.
-Holster clamps onto the mount, so one holster will accommodate ALL your pistol with the mount installed.
-Optic is stationary on the mount while the pistol fires, giving user the advantage of keeping the dot on target VS optic mounted to the slide, rocking back and forth.
-See thru iron sight for backup!
-Saves your optic from the violent rocking back and forth compare to mount on the slide.
CON:
-Generally, polymer frame pistol will have a little bit of play between the slide and the frame for the fit, because they are connected by steel insert. So the amount of play will have an impact on the accuracy. In my case, the slide moves side to side of my M&P for 1/32 inch or 0.8mm. (bullet still hits DEAD CENTER, round after round). I have found that some polymer pistol will loosen up more after use.
-You might have to compensate for the point of aim at a closer distance, because the sight sit high above the bore. In my case, my Burris (measure from the center of the glass) sits 1.7 inch from the center of the bore. Sighted in at 20 yards will make the trajectory pretty much flat out to 75 yards. but within 20 yards, or even close at 7 yards, I have have to hold above my point of aim.
(See the attached CHART below) My line of sight in relationship to the bullet impact point.
(Mind you the holster is Tight!)
