I'm ordering more Underwood Xtreme defenders because of their sale going on. My question is for my Shield 9mm, plus p or standard pressure. The standard is a 90 gr bullet moving at 1,400 pfs. I don't know if the extra 75 fps in plus p is worth the recoil and wear and tear on the gun for this application. Any thoughts?

I run HST 147 +P in mine but that’s going to feel different than the Underwood. Unless you’re running thousands of +P rounds through your gun, there is no measurable increase in wear and tear.
 
Pic shows the verbiage listed in my shield manual for reference.

I don't own a Shield, but for my 9mm Glocks, I primarily train with standard pressure and carry +P, but I think it's important to run a fair amount of your carry ammo through your gun on occasion.

I believe the extra impulse from +P will help increase reliability if shooting from odd positions, moving or having a less than ideal grip which I think are realistic possibilities in actual defense scenarios.

this is why we train & practice. I would suggest getting involved in either IDPA or USPSA clubs in your area. You'll learn things you'd never get standing at a range in front of a target.

Sorry, but I'm not a fan of gun games nor am I much of an advocate of statically punching holes in paper.
 
I run standard pressure. I have some Federal HST Law Enforcement that I think is not labeled +P, but that stuff is hot.
 
Speaking of HST, ShootingTheBull410 on YouTube, tested a bunch of 9mm SD rounds out of a 3" SIG P938 including the standard and +P versions of 124 and 147gr HSTs. From his tests, the +P versions of the HSTs only gave 2-3% increase in velocity over the standard velocity.

Federal 150g hst micro pistol. Low recoil. 850FPS, 15 inches penetration and .70 expansion. Doesn’t get any better than that.

I thought so to.But latest on line test dont show the Micro 150 HST doing to good threw heavy cloth.Problem is the velocity was running to low.They should juice that round up.I have some (but unloaded it)I will stick with my 147 Ranger T or the 147+p HST i have.I will have to chrono the 150 out of my shield before i would trust it

HST is great ammo...if 9mm+P it will be marked.( see photo)

Yeah, I know it would be marked. I just couldn't remember if it was +P or not. I usually run Hornady Critical Duty, but that HST LE caught me off guard. It seems way hotter than the Hornady.
 
Why do I go to the range to "punch" paper . So I can develop skill like a solid grip , shot placement , recoil management , trigger discipline , etc plus getting to know my firearms . As far as tactical training probably would help but I am old and slow so lol . I'm sorry but if you think you are going to buy a gun and only pick it up at the moment of need and be accurate , etc , well good luck with that . I use Federal 124 HST standard pressure defense ammo . I think Hornady is ok too loads of ballistic info out there on various ammo . Avoided + p stuff according manufacture suggestion .
 
The Shield manual states + P is ok but may accelerate wear; this is the standard S & W manual verbiage since the last century for 9 mm pistols.

To the OP's question, if your gun functions 100% with the standard load, you shoot it well and can afford to practice with it, I doubt the extra 75 fps is significant. Good luck in your decision.
 
I’ll be picking up a Shield soon and found this thread very helpful. Thanks for weighing in everyone.
 
Interesting that Smith and Wesson's "Military and Police" line of pistols are not designed to handle a steady diet of NATO pressured rounds which is used by Military and Police around the world.
