Haven't bought a new pistol for years. Looking for a 9mm to use in what we call "service pistol match". Shots fired from distances 10yds out to 50yds from various positions. Not a speed draw competition. No optical sights allowed. I would prefer an adjustable sight. What's the best choice from HK line of firearms, thanks. I have a P7M8 already, so maybe just look for another to wear out ( mine is my "baby" only had about 400rds through it in 15 years, shot 45acp when I played IPSC years ago) so I don't want to use it for match shooting.
