In all honesty. I like it over the USPc because it's sexier and comes with the O-ring which actually does help with accuracy. Trust me, I suck at shooting... I shoot the HK45c better than any gun I ever shot.
+1000...here, but if it's a HK you cannot go wrong. I shoot very well with mine but limited so far. The DA is a little heavy but use and dry fire will solve that.I like the ergo's and tapered slide and overall feel. But the pic rail is poorly designed and useless. Mag release and ambi controls are improved. Is one better than the other? No, just different.
Fixed it for you.If you look at the differences in the two, or research them - that will answer your question - IMO. Because, those are the differences - and I believe that those differences make the HK45c more desirable to some over the USPc.
It's already been addressed in most posts above, but in short:
1. Tapered slide (CCW)
2. Forward slide serrations (press check)
3. Ambi slide catch
4. Extended Mag release
5. Longer Barrel
6. Less aggressive grip (CCW)
7. Pic Rail (TLR-3 fits solid)
8. Angled frame and slide towards muzzle for easier holstering
9. O-ring snug lock-up
10. Slimmer slide catch and safety/decocker levers
11. Replaceable backstrap
I agree...nothing magical. H7K put it best - just "enhanced".
