Compared to Glock pistols, everything else is expensive. H&K pistols used to be a big name in law enforcement, but not so much anymore. Many manufacturers have stepped up to the plate and put out great products.
FYI - the MP5 isn't as popular as it used to be eaither. It hasn't been very popular for about 10 years or so. The AR platform is taking up the current market for anything that's not a shotgun or pistol. Hell, they're taking over shotguns in MOST of the country, now.
Of every one hundred men, ten should not even be here. Eighty are nothing but targets. Nine are real fighters, and we are lucky to have them, for they make the battle. Ah, but the One... One of them is a Warrior... He will bring the others back.
"Wrong door, buddy!"
Let no man's ghost say my training failed him.
