Designing the Ultimate .22LR handgun!
I'm putting together a .22LR handgun that is largely inspired by pocket sized .380ACP handguns. I want to create something that is reliable with cheap .22LR plinking ammo like Federal 550 bulk packs that you can just pick up at Walmart.
It will cost around $200 with 2 magazines. The frame, magazine, sights, and non essential components will be polymer. The slide will be aluminum. I will most likely just order short 3-4 inch rifled barrel, metal springs, extractor, and the firing pin assembly. I dread iron sights so I will design novak clone 3 dot sights as well. If your interested in learning more I've posted many more details and pictures on my blog, along with pictures I appreciate any comments on this new concept gun. |

This will be a 'blow back' action .All the recoil forces will be delt with by the recoil springs and slide weight. A lightweight slide will need heavier springs.

New 22
Thanks Mete,
Since its .22LR and the focus is High Velocity (cheap bulk) ammunition wouldn't the recoil spring and slide both have to be somewhat light in order to increase felt recoil? I have a bersa .22 long rifle that has an extremely heavy steel slide with a light recoil spring. It functions just fine with higher quality ammo but jams with cheaper high velocity ammo (bulk might as well be called SV). I'm hoping that a lighter aluminum slide and moderately tight spring would be perfect. I understand you need some tension to function correctly and I will recruit an engineer to make the final product specs. |

Cool, I would love to have a poly pocket sized .22lr. I guess the closest I can think of is the Taurus PLY .22.
Right now one of my grail guns is the little pocket Walther TPH http://en.wikipedia.org/wiki/Walther_TPH

I have a ruger sr22 and it has an aluminum slide and it functions flawlessly with the cheaper bulk ammo and even some standard velocity stuff

being an engineer myself, let me suggest you consult a gunsmith rather than an engineer. while an engineer can give you his opinion on any mechanical system based on concepts, experience is far more valuable. you want a specialist in the field you are investigating. i work on packaging equipment. you wouldn't ask me a question about bulldozers. a gunsmith with experience in 22s will be able to tell you what he has seen be more successful.

asm3686,
Is the breech face aluminum or is there a steel insert? David |

And take a look at the feed system of the P30 Grendel or Kel-Tec PMR. If they can get 30 rounds of 22 WMR in full size pistol grip why not 20 or so in a pocket size frame 22 LR? The HP22 in a very small package has 10 rounds.

ballardw, you hit the nail on the head. Its ridiculous that someone isn't designing high capacity .22LR magazines. Its very affordable to rapid fire .22 rimfire and quite fun actually.
I'm really trying to design something using ABS plastic like the Tec .22. I do not plan to use Ruger magazines because of reliability problems and will keep the magazine in the handle. The Bersa 22 magazine is a great design that allows a slight staggering for rimfire rounds. Ideally when 3D printers become main stream you could download my polymer design blue prints and just print off your own gun parts at home |

Little over 30 years ago I bought one of these for a C note. Put about 350+ WW Wildcats through her before she jammed and required cleaning. The Iver Johnson TP 22 was a wonderful little rimfire and remarkably reliable. Good luck topping it.

Your Iver Johnson is a beauty. I love Walther PP clones and have a Bersa .22 myself. The walther design is elegant but I just don't like the ergonomics for some reason. I'm designing a .22LR inspired by a RUGER LCP and SIG p238 (Colt Mustang)
I'm also going to try to use as much polymer on this gun as possible. It's going to be more plastic then the case it comes in=) |

Good advice to talk to an experienced designer. There's a reason .22 rimfire autoloaders are imfamously unreliable. The problem with .22 LR in stick mags always seems to end up being that the rim sticking out farther than the case wall throws the angle off in the mag and feeding suffers sooner or later. Even the 10-rounders have problems.
There's a pic of the rim interference at the top of this thread: "Why are .22 Pistol mags always 10rd? " http://www.theoutdoorstrader.com/thr...ays-10rd/page4 John |

Why not embrace the banana? Instead of making a plinker that also can serve as BUG, why not just make it a plinker. Make the grip and barrel standard length and then let the mag start to curl forward. Would look a little strange but many target pistols do. That would allow single stack high capacity. That alone would make it pretty desirable since only the keltec can shoot .22 with more than 10rnds in it. But those are more expensive .22mag.
But I would disassemble a Keltec mag and find out how they are the only ones to be able to make a straight, above 10rnd capacity, magazine. |

To the OP, I'd buy one of those. Great idea.

Hi Capacity .22 LR pistol,,,

I don't buy that for a second. Every full size pistol is designed around the highest capacity magazine for its size. Then they are decapped for Commie states.

I think that is one of the reasons
the .25acp is still around. The 22lr can't meet the reliability of the 25. |

For full-sized pistols. Ruger has made the statement they keep .22's to 10 round mags,,, Specifically so they don't have to have two different manufacturing lines. If they thought there was a viable market for hi-capacity rimfire pistols,,, They would be making and selling them. Aarond .

I'm not sure this is a gun you would want to bet your life on as a serious BUG.
Its has multiple variables that hinder reliability *chambered in .22LR (rimfire is one of the worst rounds to bet your life on) *Polymer material ( I am going to try to design a gun that you can print the parts out at home using a 3D printer) *High capacity magazines always sacrifice reliability in the long run. (Surefire makes great AR high capacity magazines but your going to pay for that quality; I'm going for value at the range) Overall a high capacity plinker has a huge market. If you can print the parts out and assemble a gun yourself just as a project it would be a lot of fun. Also these guns would be great in a SHTF scenario where .22LR becomes everyone's favorite round based off value and weight. I am not encouraging anyone to start manufacturing these from their home. That would be a concern for the ATF agency. |

I'd buy it, even 9 - 10 round mags, if it were in .22 WMR. Would be a nice little trail gun. Most revolvers in .22 mag are too big and heavy.

One thing at a time
.22WMR and .25ACP do not interest me at this point. The more I'm learning about ABS plastic the harder this project is appearing. I am confident in .22LR and really want this gun to be affordable.
I am most likely going to make a prototype that shoots .22 short just for saftey reasons and then work my way to .22LR. I want to create a plinker that is "built to last" and I'm not sure a .22WMR chambered gun would. Keep in mind this project is just for a .22LR possibly in the future I'll look into other calibers but right now your best bet is an existing Kel Tec. I am actually planning a trip to shot show. It would be great to have something to show off. |
