Just bought my first CCW, a S&W M+P .40C and looking for suggestions on ammo for target practice versus carry/protection. I'm new to this so really appreciate input. Bought the gun at S&W and dealer there suggested Corbon 140 gr. DPX for carry/protection. Quite pricey at 41.99 for box of 20. Later, went to local gun shop and owner suggested Winchester 165 gr. target/range for target at 43.50 for box of 100 and Winchester 155 gr. "Ranger" law enforcement ammo at 22.95 for box of 50 for protecftion since this is what police carry. So much variety in brands, prices and grain. Isn't more grain better for carry ?
