The common complaint with Army issue guns is that they are made by the lowest bidder. South Korean K5 (P51 in the commercial dress) is no exception. Back when Korean Daewoo P51 pistols became available in the US, I didn’t pick one up. I wasn’t sure what niche it filled and didn’t have a chance to try one out. The guns were milspec (it’s used as the officer sidearm in the South Korean Army) and looked the part. Recently, I discovered that Daewoo is building rather higher-grade variants for Lionheart Industries. They sell three LH9 models, standard, compact and mk2 (with an accessoryy rail). The pistols are Cerakoted, have options of tritium night sights or fiber optics, and generally look worth using.
The guns have an interesting trigger mechanism — it can be carried cocked and locked, hammer down for double action first shot or in “fast action” mode — with the hammer first cocked, then pushed forward. The trigger pull is then similar to Para Ordnance LDA — long but very light and smooth. The pistol frame is aluminum alloy, so the overall weight is 800g vs. 1kg for Browing Hi-Power (same 105mm barrel length and 13-round magazine capacity).
I have not fired the pistols I have here yet, so a range report is coming later. I like the feel and the balance, like the anti-glare texture on top of the slide and the trigger. It has no magazine disconnector. I am not wild about the way the safety works: it disconnects the trigger, so it can be pulled with no effect. I would have like a CZ/1911 type safety that arrests the trigger motion better for the sake of more obvious tactile feedback. The gun comes in a zip-up soft case with spare magazine, cleaning tools and other accessories: the first impression is very classy. It helps that GCode offers a variety of holsters for LH9: I consider them to be among the best Kydex designs made.
