USPc is a better all around gun IMO. The 23 was an issued gun, the USPc, was my personal. The frame of the Glock feels more plasticy and feels lighter so the recoil is snappier to me than with the HK. I had a V1 so I always carried cocked and locked. The lighter SA pull was much nicer to me than the heavier glock trigger. The trigger on the Glock was farther away as well, so I would sometimes only get the tip of my finger on the trigger and then have to readjust my trigger finger. The Glock had the advantage with no external safety to deal with so I did have better first shot times than with the USPc. But my follow-up shots were always better with the USP than the Glock. Mag changes were always better with the USP. I don't care what anyone says, you will never convince me that Glock mags are "drop-free". Bullcrap. The mags were always sticking in the mag well. The USP mags did drop free because of the weighted bottom and large mag well. My hands sweat profusely so both grips weren't the best. Putting a Hogue grip on both made both grips feel better. Trimming of the hogue was required for both, the USP had a better feel to it, the slim Glock grip made the hogue slide a bit under long strings of fire due to me adjusting my grip for mag changes. Oh, back to mag changes. Whoever designed that tiny little hard to push mag release button needs to be kicked in the junk. That thing is terrible. In fact, that is my main complaint with glock. Their mag release and magazines are terrible. Other than that, not a bad gun. Get the USP compact and never look back. Oh, and my final complaint about Glock, WHO THE HELL WANTS TO PULL THE TRIGGER TO DISASSEMBLE THE WEAPON?!?!
