S&w m&p 9

You have 1 gun that doesn't shoot 147 or has this been your problem with others mps?
I am talking from the experience of comparing other shooters guns at the range. Mps are like as.....s everybody's got one.
Grab a couple barrel and look down, you will see how poorly the crowns are made.
As for the 147s. The theory behind it is that the mp had been designed for .40 cal originally, hence, being very accurate in early models with 147s. And I am not making this up, all the post that are flying around the internet about the mp being poorly accurate, is whit 115 and 124 and not 147. So why yours does shoot 147 right, that I do not know.
As per the twist, the actual twist used in earlier versions had been used MANY times by SW in many other guns, the 1:10 is an European thing and probably just a marketing move, 1:10 twists (in theory) will foul more than a slower twist, physics, so which one is better? and why? where is the proof or the cientific proof? They are probably both the same 'workwise' and I doubt SW made a mistake using something else than 1:10.
Cheers.

I have several of both brands (9mm & 40). I find the S&W easier to shoot well.
Jerry Miculek states quite clearly that the twist was changed from 1 in 18 to 1 in 10 specifically to stabilize 147 grain bullets (11:20 of http://www.youtube.com/watch?v=HcR2armhilo)- I'm assuming he would know, my M&P does not like 147 grain bullets and it's an older one. 115 and 124 bullets (pretty much regardless of velocity) shoot well.

well see, that is something I believe then. All the guys complaining about the accuracy in their guns (in those old posts) were complaining how they couldn't shoot anything straight with 115 -124 and the problem would be solved (as per recommendation from SW) to switch over the heavier bullet. I remember this vividly because their complain was that they could shoot the cheap stuff, instead the had to stick to 147 and that was more expensive...
So who do we believe? an experienced shooter or the internet myth?... something to think about!

Frankly I have never heard that. Whether you want to believe it or not the 1 -1 8 twist rate is to stabilize the 9mm 147 gr bullets. My FS is from 2007, an early model and has been dead nuts accurate with everything BUT 147 gr bullets. I wish I could tell you different was but it isn't. I have had them tumble in as short a distance as 7 yards. My barrels are fine. I know there have been accuracy issues with some of the production guns but on balance I think they have been corrected. The guns now have a 1 - 10 twist, it is an improvement and it will help.

S&W changed the twist rate in 2012. I don't know the exact date or the serial number when it changed. Email S&W and they should be able to tell you. If you bought yours prior to 2012 then you have the 1 - 18 twist. Mine is the older version. The gun shoots well with 124 gr bullets so I am in no rush to replace the barrel but will when opportunity presents itself. I shoot SS in IDPA SSP and don't have the talent to make Expert so there really is no rush. A man has to know his limitations.
My PRO in .40cal shoots great with my Lyman 189 gr boolits, a gun I use for Standard division. Vogel, Leatham & Co have nothing to worry about.....Take Care

I am sorry but the fact that you have a gun the does not shoot 147 well does not prove anything.
No offence.
Like I said in 3 posts already, earlier version of those famous internet posts about inaccuracy, where great shooters (according to the writer) with 147.
What is the twist for 45 and .40 cal in the MP ? in actual and earlier versions... If the twist for 40 was 1/10 5 years ago in the mp, well then you are right, if not, well, you are just drinking the SW Kool aid.

I have an 09 M&P 9. 25K+ down the pipe.
Groups at 25y off a rest,;124gr, unique, win SPP, just under 4". 147gr, unique, win SPP, just over 8"...... I have to find a recipe or factory loading that groups well with 147s.... I have yet to find one that doesn't group well with 124s.....
Just a side note, S&W recommends changing the recoil spring & striker spring at 50,000 rounds...... Crazy!

In a lot of ways the M&P trigger is the same as a Glock - you have to learn how to work the trigger - both staging and reset before hitting stuff gets easy. If you strictly follow the basic steps of marksmanship, they do shoot well. What they don't do is make it easy, in the way a 1911 does.
FYI at IDPA/IPSC PF levels (130 ish) accuracy was no hell no matter the powder combo I used with the 147's. Last time I tried them out of say 110 rounds I would have a half dozen tumble on me. Some as close as 7 yards. My buddy down south found the same thing. His FS go back to the beginning and his PRO;s were first run. Our experiences are the same with the guns doing well with 115/124gr bullets lead/plated or FMJ. I suspect the switch to the 1 - 10 twist was motivated by the number of Police/Military units who want to shoot the 147's or want to mount suppressors on the guns and again use the 147 gr sub sonic rounds.
FYI I tried 231/HP38, HS 6, Unique, Titegroup, Bullseye and Clays under the 147's. with no luck.

Can people help me, who sells or is a distributor in GTA for Smith and Wesson? Also in Ontario. Hawthorne security is starting an armed unit. So we are debating whether to go to the Glock 17 or Smith and Wesson M&P 9mm. So looking for companies to get quotes but having trouble finding Sw dealers in GTA, southern Ontario. Any help, pm me or post here.
Why not contact S&W directly. They may give you a quote direct from the factory or put you on to their distributor here in Canada who handles commercial sales. Does the CFO in Ontario dictate the caliber and type of guns used by private security companies?

Armed Security is so grey in Ontario. I cannot find any true information but i've heard of ppl using .45 back in the day and prohibs have been know. But from what i can gather its now 9mm or 40sw like Police. As far as i know triggers are game as long as their not sporting triggers so 5.5lbs and up. Brinks uses SW MP in .40SW with stock trigger and i was told they dont have nightsights just plain white dot sights.

I believe there were some "range kit" pistols sold in Canada with the regulation 10 # trigger. have you checked the weight ? you can get the model # off the case and check specs on the Smith website if you dont have a guage.
that may have affect on your performance with it.

even though North Sylva is not a retailer they may be able to help in that circumstance. check dealer section for info
The 10 pound trigger is an LE special order item, it has a different trigger bar.
