M&P 340 CT Range Report
Finally got to the range with the new toy and various types of ammo. Unfortunately my other new toy (chronograph) had issues which I can fix, but no velocity numbers to report on the 340 (got a few on my M&P 40C but that's another thread).
I'm a semi-auto guy; never shot a revolver (as long as you don't count a .22 when I was a kid). Based on a lot of reports, I was prepared for the worst recoil-wise. Short answer: t'aint that bad.
Given the chronograph issues I was not going to burn up a lot of ammo just tossing it downrange, so loaded up a few of everything I had just to get a feel for the pistol (accuracy not particularly monitored or striven for, but most rounds hit a 12" target at about 10 yds; also, bullet jump (if any) not monitored).
5 rounds of .38 Special PMC Bronze, 132 gr FMJ for a baseline. Pretty tame. This stuff is dirty (no surprise); power residue evident in the cylinder when the spent brass was ejected.
5 rounds of .38 Special +P Buffalo Bore 158 gr LSWHC. Now we're shooting something, the recoil told me. Not bad, but it's barking now
5 rounds of .357 Mag Buffalo Bore 158 gr JHP Tactical Short Barrel Lower Recoil. Perceived recoil seemed about the same. That surprised me.
2 rounds of .357 Mag Hornady 158 gr XTP Custom immediately followed by 2 rounds of .357 Mag Hornady 125 gr FTX Critical Defense (no reload). Both of these are a handful, couldn't really say any worse than the .357 Buffalo Bore, or not terribly worse, but I am now aware that the 340 has a steel backstrap. A Hogue grip would probably be more comfortable than the Crimson Trace 405.
2 rounds of .357 Mag Remington Golden Saber 125 gr JHP. Recoil seemed about the same as the Hornady.
I'm probably insufficiently familiar with the pistol to gauge the recoil at this point (I can easily tell when switching ammo in my M&P 40C), but the bottom line is that the M&P 340 is quite manageable with the above loads. I wouldn't want to shoot a hundred rounds in one sitting, but I suffered no ill effects from the short stint above. I must say that the 340 does not point 'naturally' for me, and my grip feels 'contrived' (I'm doing the hook left thumb over back of right thumb joint in order to control recoil -- this is not the grip I use when shooting a semi-auto).
I'll be making some chronograph 'repairs' later today and try to hit the range in the A.M. and get some hard numbers on this ammo.
