M&P9 Accuracy issues... is it me??

[MegademiC]

Even the bad mps shot 9" ant 25yds from what I've seen. 7" at 10 sounds like a shooter issue. Try to find a good shooter to test it for you.

You need to start eliminating some of the variables.

First I'd change your ammo, old carry ammo or anything of a known decent quality.
Second I'd probably unmount the RMR and shoot irons only.
Third get someone else to shoot it.

Also it's hard to imagine that big of groups at such a close distance? Either turn off or remove the optic and with the irons shoot at 5yds at a tiny paster. You should be able to obliterate it at that distance. Then move it out until you notice the problem if any with the irons.

What's the twist rate and what is the ideal twist rate for 9mm?

Twist rate is really irrelevant at the distances most people shoot pistols at (FYI).

Have you shot it with just using the iron sights? You listed quite a few guns you had success with. Unless you had a RMR mounted on all of them, I would look there for an issue.

A lot of people don't shoot Red Dot Sighted pistols well as they do not like all the movement they see with the dot. It is a learned skill to shoot them well IMHO.

I had awful luck with the factory barrel also, which is why I decided to send it out to get a fitted barrel. Would anything change by trying it again?

We shoot the fitted barreled slides for group at our indoor range. They will shoot at least a 2" group at 25yds and have recorded SUB 1" groups before.

Something is definitely wrong there.

I have a 9L slide with SL barrel fitted by Grant with a RMR cutout from ATEi. This was unsupported slow fire @ 15 yards (closest photo I have to 10 yards):

If you're having problems with that setup, I'd assume there's an optic mounting problem, jacked up optic or possibly shooter error (no offense). Are you seeing any change in zero on the RMR relative to the irons?

This is the norm from what we see on our end. The RMR could be the issue and is not holding zero (seen this before).

Are you shooting off a range bag or what?

I ask because of a tip I got on the Brian Enos forum years ago regarding M&P's. The tip was to not rest the gun on the bag but only rest your arms on the bag. It greatly improved my accuracy and groups with the M&P. But, I've never seen someone shoot a 17rd group. I probably couldn't focus that long.

I was shooting unsupported. I shoot groups based on magazine size. If I was shooting my rifle at 100 yards then I'd keep it at 5 rounds for a bench mark, but I feel like ammo shouldn't make that much of a difference at pistol distances.

Has any one else shot this m&p? Not saying it's operater error but it would help to get a better diagnosis.

I don't really know anyone that can shoot precisely with a handgun.

I don't take offense to it, I'm sure I'm better with some guns than others. I'm generally pretty precise with handguns and I figured that I could squeeze at least some respectable accuracy out of this gun, especially considering how much money I've dropped into it.

If you know anyone in the Tampa area, I'd love to hit them up. I don't know anyone that can shoot a handgun precisely.

I'm sorry if I came off like I was blaming the barrel. I'm definitely not and I strongly feel that there are outside factors here. I'm going to mount the RMR on a few different weapons (another handgun, my AR15, and maybe my shotgun) to see how it reacts. For some reason I didn't think to try shooting with irons.

I'm also going to try a different trigger, I still have my old CompAEK laying around. Maybe that trigger isn't working too well with me.

Maybe I'm wrong, but how much of a difference will ammo make at 10 yards? Do they even make precision hand gun ammo?

Not a lot. Yes, there are some companies that do.

Most of the "precision handgun" ammunition seems to be for 22's for match. Sure you can hand load to achieve "greater accuracy" but unless your shooting 25 yard bullseye then whats the point? I can say that some guns shoot certain brands or bullet weights better than others, yes I'm referring to handguns here. I have a Sig MK25 that shoots 115 gr FMJ better than 124 FMJ but then again it shoots 124 +P GD's perfect so yes sometimes it depends on the gun. More times than not, the issue pertain not to the gun but the jerk behind the trigger. (Note:I am not calling anyone a jerk but rather a reference to jerking the trigger)
