A Heckler & Koch P9S pistol in Lego, with moving slide.
About this creation
H&K was formed in 1949, manufacturing the G3 series rifles for the German Bundsweher. Their first pistol design, the HK4, could use 4 different calibres by switching barrels, and their next, the VP70, was the first pistol to have a polymer frame. Neither were great successes however, and their third design was more conventional, although it did use an interesting locking system. This system was roller-locked delayed blowback, also used in the aforementioned G3 series, and, until recently, the mainstay of all HK rifles. Put simply, this system uses a bolt with little rollers [think paint rollers, painting horizontally] on each side. When the bolt was forward these rollers fit nicely into recessed in the sides of the receiver, and when the gun fired the bolt's rearward movement was slowed, because the rollers had to roll into the bolt for it to move. This kept the chamber closed until gas pressures had subsided [all rifles have some method of locking the bolt closed; the time it takes for it to move back and forth is still EXTREMELY fast].
In any case, I wanted to make a pistol with a moving slide, and went ahead with the HK P9S design [the S indicates double-action]. I also tryed some new things with texture on the grips, as suggested by TheQ of LAML. So, have a look and tell me what you think.
Left side. You can see what I mean about the ejection port. When seen from the right it looks like it goes all the way across the top of the slide in a big square cut, but really it only cuts into the right hand side.
Slide retracted, from the front. My pistol does not have slide locking switch, these pictures are staged with an internal locker to show you what the slide looks like when back, without my hand in the way.
Pretty awesome P9S, it would be nice to incorporate a bigger magazine into the grip, but I have tried, and it just makes the grip unstable. I like the grip texture, it really gives it a rugged look. Great job.
Your Gunsmithing is getting much better. The wing that hangs over the hand at the back appears a little short. Here's a challenge: try to expose a bit of barrel when the slide comes back like the real thing. I don't like the handgrip texture, sorry. The trigger guard is looking better. Now just to figure out how to smooth it out. Your ejection port is looking good. Great sights; I never thought of that. Good job on the slopes of the gun. The front of the real P9S is a little squareish, so you didn't do a bad job on that. But, 4 studs is a little wide as I discovered with my Glock. 3 studs is hard to work with though, so there's a tradeoff. Keep up the awesome work. [4/5]
