J-Rob Posted March 18, 2010 Share Posted March 18, 2010 I took my new m&p full size 45 to the range today and shot 100 rounds of 230gr fmj out of it and its grouping 3 inches left and about 5 inches low at 15 yards. I couldnt believe the performance I was getting out of this m&p since I own 2 others and they group POA/POI. Anyone else here experience this with your M&P's?

Nik Habicht Posted March 18, 2010 Share Posted March 18, 2010 Does it group? Then it's accurate. The group might need to be shifted -- but that's fairly easily accomplished..... Did you shoot it off bags, or freestyle? Link to comment Share on other sites More sharing options...
J-Rob Posted March 18, 2010 Author Share Posted March 18, 2010 I shot it from a rest at the shooting range. I always try to do it with brand new pistols just to make sure that the sights are on point. Link to comment Share on other sites More sharing options...
ParaGunner Posted March 18, 2010 Share Posted March 18, 2010 Sounds like you need to drift the rear sight to the right and file down the front sight some. Link to comment Share on other sites More sharing options...
RH45 Posted March 18, 2010 Share Posted March 18, 2010 If it is shooting 5" low, the first thing I'd do is to try a varity of ammo and if it continues, a call to S&W would be in order. Link to comment Share on other sites More sharing options...
G-ManBart Posted March 18, 2010 Share Posted March 18, 2010 Make sure that the front sight is properly centered in the dovetail. The FS on my Pro was off quite a bit and I've heard of similar things from others. The good thing is it's an easy fix. As far as elevation goes, it could be ammo related (was it factory or reloads?) or it could simply need a different height front sight. R, Link to comment Share on other sites More sharing options...

Im gonna try some Winchester ammo and some others too if I can find any in stock. Link to comment Share on other sites More sharing options...

Then it's less likely to be you..... Try some different ammo, center the front sight, pay careful attention to trigger pull to make sure you're not yanking the front down, have someone else shoot it.... If it's still low with the ammo you want to use, then consider a shorter front or filing a little off this one.... Link to comment Share on other sites More sharing options...

R, That was the issue with my full sized M&P 45 (non L.E. pistol Sku) I had to true up my front sight post and it still shoots about 2-3" left at 15 yards. Elevation is good though. I may end up drifting the rear sight over a bit once I'm confident that it's not just ME "glocking" the trigger. Link to comment Share on other sites More sharing options...
Lumpy McSoo Posted March 28, 2010 Share Posted March 28, 2010 (edited) The left/right issue can be easily fixed by drifting the front/rear as needed. What is the height of the front sigth? In my full size 4.5 inch barrel M&P 45 I prefer a 0.170 inch high front. Shoots just a tad high at 10-15 yards which is how I like my pistols to shoot. I like to see the hole just above where the front sight is. I guess this is from shoothing clay targets for many years where I would like my pattern to be about 65/35 high. I like to see the target just above my front sight, not having to cover it up. Just my two cents. By the way, this was with a Burwell rear sight not the factory sight. Good luck. Later, Lumpy.
