I have switched to the Federal 130 HST Micro which IS +p rated but does not recoil as bad as the 158 grain loads and the 642 is plenty stout ! This load is devastating in the recent testing i've done and just does nt blast and roar and kick others I used before.
It is perhaps worth noting that the OP asked about a *640* Centennial, not a 642 or other airweight. The 640 has always been a steel-framed revolver, heavier and stronger than 642s. It could have been a typo, I suppose. Even the older, .38 only 640 Centennials are plenty strong enough for any current plus P loads, so I assume recoil might be the issue.

Hi Gary, you are correct. I am speaking about the 640 Centennial. Recoil isn’t my concern. The reason I’m inquiring about Standard Pressure ammo is because although the 640 is a steel framed gun, S&W state’s that they don’t advise shooting +P Ammo thru any of their guns made prior to 1997. They also stated that the gun was not tested for +P. On the other hand, I’ve heard people state otherwise.. basically what you said. It’s strong enough to handle +P ammunition.Standard velocity HBWC. Bullet is already in an efficient shape and has adequate penetration.
I was carrying Speer Gold Dot 135 gr. +P but was told by S&W that even though the 640 is a steel framed gun, they don’t advise putting +P thru it. They told me that the gun wasn’t tested for +P ammo and that I should use Standard Pressure. They also told me to stay away from Buffalo Bore & Underwood ammo because they don’t meet SAAMI specs and are too hot. Im hearing different things from different people..Buffalo Bore or Underwood Ammo standard pressure wadcutters and sem-wadcutter hollow points. Anything's better than nothing though.
Hey Thomas, the reason why I was inquiring about Standard Pressure ammunition is because i was told by S&W that the 640 Centennial wasn’t rated for +P ammunition. I’m hearing different things from different people. The NYPD had us shoot 135 gr Speer Gold Dots +Ps thru them even though someone from S&W told me that +P’s shouldn’t be used in any gun made prior to 1997. I bought mine in 1990.I wondered why the OP wanted non +P ammo and just thought it for lower recoil. Since his gun is rated for real 38 Special ammo it will easily handle the +P loads that are at best the same as original 38 Special loads. Reducing bullet weight goes a long way towards reducing recoil.
Hey Gary, recoil isn’t my concern.. damage to the revolver is. I was told by S&W that the 640 although very strong shouldn’t have +P ammo thru it. They told me that the gun is rated for Standard Pressure. That confused my because I purchased the gun in 1990 while working for the NYPD and the department issued us Speer Gold Dot 135 gr +P ammunition. Very surprised that they would go against what the company recommended.Winchester Defend, 130 grain, has gotten some good reviews. It did pretty well in the Lucky Gunner tests. https://www.luckygunner.com/labs/revolver-ballistics-test/. The 640 Centennial is noted to be a very strong J-frame. Is your reason for using standard pressure for concerns about the revolver or concern about recoil? Some of the earlier Model 640s were factory marked “+P+” and it was chosen as the base for the first J-frame .357 because if its inherent strength. Aside from the Winchester Defend ammo, I favor plain 158 semi-wadcutters in standard pressure.
