Reloading for S&W M&P Compact 9

[ronas]

I've been using 115 g Berry plated bullets loaded to 5.1 grains of 231. I know that may sound high but when I used the load I've used for years with Beretta 92 FS I had nothing but jams and failure to fully cycle the action. The Beretta load is 4.7 grains of 231.

I tried 4.9 and still pistol would not fuction reliably. Then 5.1 and have not had any problems.


Well I now want to load up some Winchester 124 grain FMJ bullets with flat exposed lead base. All the recommended loads I've seen in my manuals are so low I can not imagine they would function in my pistol. The only exception is my Speer manual which for a round nose flat base bulllet with a cannalure weighing 125 grains. The manual shows 5.8 g to 5.2 grains of 231. Now that sounds about right. Manual is third printing, February, 1981.

Not sure what to do. The loads in the new manuals and Hogden online data center are very very low for max. load.

So anyone shooting a S&W M&P Compact 9? It's a great little pistol and if anyone is reloading for it or has a suggestion I'd be interested in your load and/or input.

I feed my 9c the same stuff I do my G17, EMP. It has handled light loads just fine. Current plinking load is 4gr titegroup under a 124gr rainier. Tested 115gr xtp's with 6-6.5 gr power pistol. In .1 gr increments they all functioned fine.

My M&P9C eats the same thing my full size M&P9 and Sig 226 eat, 4.5 grains of titegroup with a 115 grain FMJ from Precision Delta. About 1500 rounds of reloads and no problems, about 1800 rounds total.

I shoot 3.5 titegroup under a 125 grain westcasting match projectile. Gun cycles 100% and shoots some nice groups at 30ft. Thats odd your gun won't funtion with a lower velocity load. I have loaded 3.0 grains under a 115 fmj for the wife with no hiccups. Sounds to me like a possible crimp issue?
