Recently bought MP 40 full size Put 80 rounds Winchester 180 grain white box thru it could not hit a thing with it My wife has a 9C .I have no problems holding 2 inch group with it Looking for any advice on possible mods Trigger or Sights ? Is it ammo specific Or do i just need to shoot the hell out of it
 
Can you be a little more specific? What distance from the target? Standing two handed isosceles style or rested on a bag from a bench? Where you getting any kind of a group or were your shots all over the place. Are you right or left handed? If you had groups were they low left, low center, etc.?
 
Try a 165 gr load. The recoil is in my opinion "soft". The muzzle energy rivals a 357 magnum with the 125 gr bullet. I don't mind shooting my shield 40 at all. At 7 yds which is in my opinion about as far as you need for civilian self defense I can keep them all in the kill zone.
 
My M&P 40 from 2007 is exceptionally accurate, 165 & 180 grain loads. Try different backstraps and benching it. Also if you have dummy rounds mix some into the mag and see if your flinching or pushing the gun.
 
Shooting a 9mm and a 40SW are 2 completely different experiences. The 40 often will make a 9mm shooter cry after shooting it. Keep at it and try resting on a sand bag to keep it steady and really work at your trigger control. I remember shooting my M&P in 357 sig the 1st time, neither I nor anyone else I had shoot it were very good at it... I put it away for year, I was so disappointed.. well during that year, I shot a lot of 45acp through various guns including my TR325... when I decided to get rid of the 357 sig a year later, I brought it to the range for one more trip to get rid of the extra ammo... I was amazed, right out of the box I murdered the target, as good as any gun I shoot.. so, to sum it up, the kick going from a 9 to a 40 can make one cry... work at it, you'll get it right, the 40 M&P is one of the better guns out there..
 
I'm not sure if this is a thing or not but it happens to me with the 40. I own several guns in 40 but they are the only ones I'm accurate with. I have a HK P2000 in 40 that's I can't miss with but my HK USP 40 I couldn't hit a single thing. My Glock 22 is very accurate but when I had a Glock 23 i was awful. Don't know why that is
 
I'd check it over to make sure everything is tight. I recently had a issue with mine while at a training class. Went from good solid hits on target early on, to my groups falling apart. It was the end of an 8 hour pistol course, and I chalked it up to fatigue. When I got home and started to take the pistol out of the range bag to clean it, I noticed the rear sight was overhanging the slide by about 1/4". It turned out the sight had come loose and could easily be moved by hand.
 
My newly purchased 07 model .40 is EXTREMELY satisfying, I will admit I can shoot it a lot better than my GLOCK. I love this sucker!
 
I have both a 5" Pro Series and a Shield in .40S&W and love them both. However, the M&Ps aren't really target guns. That said, you should be able to hold acceptable self defense groups out to 25 yards or so. I shoot Winchester white box all the time and don't have a complaint about accuracy.

The triggers on M&Ps aren't the best. A lot of people on this forum, including myself, have installed trigger upgrades from Apex Tactical. I have their Duty/Carry Action Enhancement kits in both of mine and feel that has helped accuracy considerably.

This target was from 30~35 feet. I can do better with my 1911, but for a night stand gun, I'm satisfied.

I took my newly issued (NIB) M&P40 and fired it the same day I took it out of the box, and then again the next day, using a mix of current and previous duty loads (180gr). While I'd field-stripped it and checked for anything visibly amiss before shooting it, I didn't lubricate it for the first session (and it was essentially bone dry).

Both times I was pleasantly surprised by the practical accuracy. I found it a bit more enjoyable to shoot than my well-worn M&P40c (from 2010), and even my well-used M&P45 ('08). Of course, I also liked using a T&E Shield 40 more than my 40c (again, with 180gr loads), which seemed a bit odd, at first.

Let's just say that making called hits on wooden clothespins (holding the paper targets on the cardboard back board), shooting 2-handed, unsupported, was an enjoyable way to test my shooting with the new duty gun once the qual shooting was out of the way. Nice.

Another of the senior instructors, who owns a M&P40 & M&P45, said his M&P40 is the softest shooting duty-size .40 he's ever fired, and also has no complaints about the inherent & practical accuracy.

if I had any more interest in owning a service-size, hi-cap pistol, I'd be hard pressed to decide between the M&P9 5" Pro and the current standard M&P40, as I've enjoyed using examples of both on the range. The new production M&P9 5" Pro I was trying (belongs to yet another instructor) almost makes it seem like having an unfair advantage. ;)
