Yes, albeit with a caveat. Here's what the manual says on page 9:cajun47 said:its ok to shoot +p in the shield?
There IS a SAAMI pressure specification for 9mm+P, so this statement implicitly endorses its use.S&W said:Use only commercially manufactured ammunition with internal ballistic pressures which are in strict accordance with the specifications of the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI). If you are uncertain, contact your ammunition supplier for verification.
So there you go. +P may require more frequent service, but the manual doesn't outright say "We Won't Service It." OTOH if you use +P+, you're on your own.S&W said:“Plus-P” (+P) ammunition generates pressures in excess of the pressures associated with standard ammunition. Such pressures may affect the wear characteristics or exceed the margin of safety. Use of “Plus-P” ammunition may result in the need for more frequent service.
“Plus-P-Plus” (+P+) ammunition must not be used in Smith & Wesson firearms. This marking on the ammunition designates that it exceeds established industry standards, but the designation does not represent defined pressure limits and therefore such ammunition may vary significantly as to the pressures generated and could be DANGEROUS.
In the S&W owner's manual I had for my full size 9x19mm M&P pistol, it stated it was safe to fire factory made +P & +P+ loads.
I was going to point out the same thing.MrApathy said:I havent seen a S&W manual that stated +p+ was safe to use in fact the manual states +p+ ammo is potentially dangerous. S&W sticks to saami standards.
FWIW I'm not comfortable carrying FMJ because of overpenetration concerns.Ibmikey said:...my carry Sig 938 loves [9mm FMJ] so for me that is what I shoot and carry.
When we redesigned the Ranger T Series of ammunition we widened the velocity window under which the round would expand to allow for the slower velocities that shorter than standard barrels produce. What this means is that if you own a standard or sub compact pistol the round should have adequate expansion. In 9mm I would recommend the 147 grain bullet as it loses a lower velocity percentage than the faster lighter bullet in shorter than normal barrels. This is because the bullet has more dwell time in the bore and has a greater opportunity to burn the powder before the bullet exits the bore. Powder that is burned outside the bore does nothing for velocity. The lighter faster bullets generally have more powder to burn and since the lighter faster bullets have less time in the bore they are not efficient burners of powder in the shorter barrels.
We increased the velocity window under which the round would expand by increasing the size of the hollowpoint, tweaking the jacket thickness and the depth of the cuts on the inside of the jacket petal segments.
