How much of a difference in recoil is there between a normal .38 round and a +P .38 round when firing a 340 M&P?
Regarding recoil with a 340??

I percieve very little difference between .38 spe. and .38+p. However when you go to .357mag, there is a big difference in recoil. I shoot all in my M&P 340. If you start with .357 mag for about 20 rounds and then switch to .38 spe +p, you will think you are shooting a .22

It'll really depend on what loading and with what weight bullet your discussing?
A 158 grain .38+P @1000 FPS in a 13 ounce gun, may tear you up more than a light loaded 110-125 grain .357 Mag. Also a great deal depends on what grips your running, too!

S&W does not recommend anything less than 125gr. when using .357 mag ammo in the 340M&P

The 340 M&P has a stainless steel cylinder and is not subject to the bullet weight restriction that the titanium cylindered guns are.

Hmm, my manual said nothing of that in it. I thought that was for the titanium cylinder guns? I don't notice much of a difference in preceived recoil either between 38 & 38+P.

Just took my new 340 M&P out today. Wad cutters no problem, 147 grain +P+ 38 a little snappy. The 158 grain 357 oh my god they hurt. I'm not a small guy and have no prob with 44mag, but 357 in the 340 just jarred the hell out of my hand. So I'll be carrying the +P+'s in it.

You are correct, I stand corrected, the steel cylinder on the 340 does not have that restriction, the ti cylinder on the 360 does.

D/G 95,
I admire your honesty about shaking hands with her! Too many feel it's a sign of weakness somehow saying that MF'r is capable of putting hurts on both ends!

I'm shooting .38 135 gr Speers with no problems. Great round and have tried the .357 to satisfy my curiosity. I'll stay with the .38 for a much more manageable 2nd shot.
That's my experience with the 340PD too. .357's = Serious Ouch!

I have a 340PD, on which I've mounted Crimson Trace LG-405 Laser Grips. The grips make a huge difference in the "shootability" of the little beast. I keep mine loaded with Speer 135gr. Short barrel .357 mag ammo. With the CT grips and that ammo, the 340PD is less abusive than is my 342 with Spegel Boot Grips and +P .38s, at least to me.

Speer SB .357s go a long way in aiding shootability. They are perfectly suited to the little monsters. Full power 125 gr. .357 beat the snot out of me and aren't doable. SB .357 are stout, but I can shoot them well. FWIW I use wood grips on my 360 PD.

Try the Speer 135gr .357 Short Barrel Ammo. It's a little more recoil than the same bullet in the 38+P.

The Crimson Trace grips solve the two biggest problems with the 340 -- recoil and aiming. The grips provide a larger area for the hands (increasing control-ability) and cover the back portion of the frame. It's this back portion that slams into your hand with each shot. The laser grips also greatly aid in hitting the target. Let's face it. The sights on this gun are basic, small, and with the short sight radius, difficult (at best) to use effectively.

Admittedly Reg, every word you said is true!
But the fun with the little fart's sometimes comes from working with them long enough to get good with their iron sights too! They're really quite amazing in their capabilities.
BTW: WELCOME!
