I forgot to update. When shopping around, I came across a new H&K P30L in .40 at a great price, and ended up getting that.
I know that's a completely different direction than I originally intended. I decided on consolidating my centerfire pistol chamberings down to 9 mm, .40, and 10 mm Auto. I reload for all 3, and have multiple pistols in each chambering (two is one, one is none). I have plenty of brass, primers, bullets, and powder. I sold my remaining .357 ammo and decided to concentrate on those three. Keeping it simple....
Lastly, I have a few other HK pistols and figured I couldn't go wrong adding another. I love the P30 so far. My only complaint is the SA reset is kind of long (even compared to my USP triggers). Might need the Grey Guns short reset kit.
