The grip can not be complained about...you have a gazillion grip combinations...but the magwell sucks,..and unless you are used to using a paddle release mag release, you will have to use it exclusively to get it into muscle memory.
The trigger can be bettered but not keeping you in production division,..unless there are lighter hammer springs and firing pin block springs available. Yep...parts are not "readily" available, and you pay a premium for them I would imagine. Magazines are overpriced if I recall...like $75 each?
You can get sights for them,..like fibre optic units. ONe thing you get when buying one is that they are more reliable than most guns I see at the range...
I have high hopes for the VP9,...better trigger (striker fired in the 5.5 lb range), lower bore height,....although I forget what the magwell looked like, I do not think it changed much. I handled one in Florida,..everyone I saw handling it commented on how comfortable it felt in the hand. They are numerous reviews on youtube of the VP9, and my advice would be to wait and get the Canadian version of the VP9, and forget about the P30L,...if I had to compete using one, I would get a P30L-S.
