HK's 45, perhaps the most comfortable handgun chambered in 45 ACP on the market is worth every dime. Developed and used by U.S. SOCOM, the HK 45 is a vast improvement over the giant HK Mk. 23 and incorporates many modernized features from the USP line. All in all, the HK 45 is outstanding. Magazines for the HK 45 are high quality, made of steel and feature a solid floorplate for years of use. HK uses quality springs that allow for prolonged timeframes where the magazines remain loaded. The HK 45 ships with two of these 10rd magazines...why not pick up a few more?
