the posterior of the slide to the left of the spurred hammer. Single-action trigger pull of (+4/-2 N), double-action trigger pull – (±5 N).

Ammo The P2000 manual clearly states that HK does not recommend the use of +P and +P+ ammunition in P-series pistols: The revised manual (2014) removes this recommendation, stating that P series handguns are designed for brass-cased ammunition, factory-loaded to NATO or SAAMI specifications. The revised manual continues to warn against the use of steel- or aluminum-cased ammunition. P2000SK The P2000 SK model is a smaller "sub-compact" version of the P2000. American versions of the P2000SK will accept the longer USP Compact magazines which provide higher capacities; up to 13 9 mm rounds and 12 .40 S&W/.357 SIG cartridges. Some of the advantages of its compact size will be compromised as these longer magazines will protrude approximately 1/2" below the bottom of the P2000SK's grip. Lower capacity 10-round magazines are the same size as the higher capacity USP Compact magazines.
