I like my USP45CT a lot. Still, as I shoot more and more with it, I realize that the flat sides on the grip make it more difficult to hold solidly for fast follow-up shots, compared to, say, the HK45 or P30, or a P220. I’ve had to work hard on engaging my pecs, to press my palms together to keep the gun from shifting in my grip. As I shoot more with different guns, I am definitely leaning toward the HK45 as an upgrade. Especially with the interchangeable backstraps, the way the grip fills my palms makes it so that a more natural-feeling grip keeps it in perfect control.
Also, it’s been said that HK magazine springs suck. I have 7 mags for mine, and I do get the odd failure to lock back, as well as the odd failure to feed during a reload - especially when causing the slide to drop by slamming home a magazine, and most especially with the extended 10-round mags. I used to attribute these failures to myself, but I now strongly suspect the mags. I’ve just ordered some Wolff mag springs, we’ll see if that helps.
Finally, the trigger is definitely odd. I don’t have a v1, not the LEM, and it’s been said that the LEM helps a lot. But my v1 is gritty, and it has a “fake” reset, where it clicks a little before it fully resets. I have to be careful not to short-stroke it on follow-up shots. I’ll also second someone else’s post about it feeling like you can snap the trigger by pulling it too hard while the safety’s on.
With that said, I’ll repeat: I love my USP45CT. It’s taken a beating during 1600 rounds and daily CCW by this clumsy noob - even the finish is still great. It eats Wolf ammo like a champ, which keeps me on the range longer. It’s easy to clean - I just dump the whole field-stripped mess in a bucket of Ed’s Red for an afternoon, then scrub for 10 minutes with Hoppe’s bore cleaner to get it pretty much spic and span. I’m in the process of putting it through the “2000-round challenge” - so far it’s got 475 rounds of mostly Wolf and Blazer with no hiccups other than 3 FTF’s during reload with the 10-round magazines.
