Yahhhh...
No +P
And, stay with pure Lead Bullets, no 'jacketed' or 'Hardball'...
Any standard loading 'SAMMI' compliant .38 Special Rounds of usual 'Round Nose Lead', or, lesser power mid-range Wadcutter types will be fine.
My own favorite Loading for S&W 'M&P's of that period or earlier, is as full house as will fit of 3f BP ( being about 20 Grains ), thin home-made Grease-Wafer between Powder and Bullet, and, 158 Grain RNL or pure Lead Hollow-Point Bullet.
This will give better than 'SAMMI' Velocities, and it entirely safe and easy on the Arm.
