First, I've had my Kimber Solo for over a year now. I carry it on warmer days when I'm wearing shorts or in an ankle holster when I'm wearing a suit at work. I have close to 1000 rds through it and have not had any problems. The street ammo I've been using is 127grn Ranger T +p+. I've been reading about 147grn HST and it sounds like a good, effective round. I am looking for opinions on what would be a better round for a short barrel pistol (eg. deeper penetration) a lighter faster round like the Ranger T or a slower heavier round like the HST. Thanks.
