I know the manual says no +p or +p+, but do you guys think the speer 200gr +p gold dot will hurt the M&P45? I got a good deal on a case. FWIW, I would hate to hear that the M&P is a non +p 45, especially since S&W wants to compete with Glock.
How the hell does being a "plastic" gun have anything to do with whether or not it should be +p or not?? The cartridge is still being discharged in an entirely metal chamber. Please elaborate on your opinion, that makes no sense whatsoever to me. In fact I shoot 185 gr +P GS and they actually feel SOFTER than the 230 grain Remington's I practice with! The standards set forth by S&W have nothing to do if the FRAME can handle the loads and pressures, its all about the chamber and action holding up to it.
Plastic pistol has nothing to do with it. In the case of the M&P the stainless chassis is embedded, or rather cast, into the polymer portion of the frame. The slide and barrel are steel. +P has cracked plenty of steel and aluminum frames anyway.
I'm a big slow bullet fan that penetrates and crushes bone and gets into organs. I also like a regular JHP 230 grain .45 round because it has the same recoil impulse and same point of aim, point of impact, as a practice hardball round.
If you like .45 in +P more power to you. ;-) I carried +P 200 grain for a short time in the past but have returned to 230 grain hollow-points.
Personally I would not use any .45 against a bear. Minimum of 10mm for a semi-automatic but better to have a big honkin' revolver round.
Test Event 2 - Heavy Clothing. The gelatin block is covered with four layers of clothing: one layer of cotton T-shirt material (48 threads per inch); one layer of cotton shirt material (80 threads per inch); a 10 ounce down comforter in a cambric shell cover (232 threads per inch); and one layer of 13 ounce cotton denim (50 threads per inch). The block is shot at ten feet, measured from the muzzle to the front of the block.
I like CorBon's standard pressure 160g DPX. Penetrates and expands just fine (at least 12/.75 in bare gel and through 4 layers of denim), kicks less than the 230s, has more energy than the 230s, and even CB's 185 +P DPX.
Any other 230 JHP is just fine by me too, usually carry 230 GDs.
I continue to be interested in Corbons DPX from what I have read about it. They also have a 185 grain version I believe. It does violate my 230 grain rule but it is still an interesting round. I think Evan Marshall carries the 165 grain Corbon DPX. In case anyone thinks that is significant.
