I agree it's an excellent value. For a primary handgun in a SHTF world though, I'd prefer something that uses a more common military/police round, (9mm, .40, or .45) and known for exceptional reliability and low maintenance. The more popular and common the gun, the better. This kinda hurts the H&K because there aren't that many out there due to cost, but they are very reliable and low maintenance.
All I recommend the CZ 52 for is varmint control and plinking.
Its like a little 223 in your pocket!
For defense I like the 40 S&W
