If they are going to refresh the pistol, do it right. Like the glock gen5, improve all parts of the pistol.
1. fix the trigger return spring design to one that mimics the beretta m9's bomb-proof version.
2. fix the firing pin retainer pin issue.
3. redesign the slide so there is more metal from the chamber area on back (the way it tapers now, doesn't leave a lot of metal for the front lugs on a rmr/holosun cut.
4. add a independent locking block. (instead of using the slide stop to catch the barrel lug)
5. move the decocker to the rear of the pistol like the hk p30.
6. improve the pistols grip.
7. create a new size (p-08) 4-inch barrel and grip length in-between the 07&09, 17 rounds, like the glock 45.
I would be shocked if they did update it. I don't think they are spending another second on this platform. It would be nice tho, I only appendix carry hammer guns.... if hk ever updated the p30 slide to accept a red dot, that would be perfect, as it is now the p30 with trijicon hd xr(s) are as good as it gets right now.
