It comes down to how many similar guns does one require. I like the LEM, V1 9mm version if I were to purchase a new H&K. The money isn't "that" big a deal unless you really are stretching to purchase the gun. I just picked up a Glock 30 "S" after owning one for 20 years without the "S". It is a terrific gun, at 30 is 31 ozs with 11 rounds of 45, I am content with, this and the others I own. If I were to buy another plastic pistol right now, it would be the Walther "for the size, capacity, weight ,and trigger, let alone the value.
I don't see any of the others able to do anything better than the Walther.
There comes a point where you have to ask yourself, "why am I buying this again"?
Another contender for me is the CZ P01, same amount of rounds great looking, accurate, and the trigger is OK, "the tactical version" is better with the Omega trigger. But it's a metal gun, so I like that. They also have a custom job with the wood grips tritium sights and target trigger for about the price of the P30.
I am noticing that many gun manufacturers are not pushing the 40 caliber any more, I stopped a few years ago, and went 45 and 9mm only.
Cz doesn't make a 45, and has problems with the small guns in 40, the PCR and P01, Walther pushes the 9mm as does Sig and HK.
Soon 9mm ammo is going to tighten up at this rate.
