Thank you… the family member is a bother who opted for .40 M&P as his target pistol. He’s not new to shooting, but “liked” having a round that was cheaper to shoot then .45 ACP. I understand the ballistics of lower grain, flatter trajectory but was curious about the folks here, there experience with the .40 round. I personally shoot 9mm, use 147 grain for steel plates, switch to 124 grain for paper targets out to 25 yards,,. XS Sights… so my POI is consistent.

Based on the comments, I’ll suggest 180 grain as this is probably closer to his defense shooting needs (lighter grain longer distance for target) relative to <10 yards for close engagements practice.
