Kitbash: Rugaurus LTCP

The firearms industry is at its best when creativity and hard work combine to create something that’s truly innovative and great… But that’s not always what happens. Sometimes, the quickest way to get a product on the market is to simply copy what’s already out there. It’s no secret that guns like the S&W M&P orΒ FN FNS-9 are clones of the ubiquitous Glock, or that the subcompact market is dominated by guns that are all basically clones of each other, but the degree to which some of these models match up with one another can be surprising. For example, take the Ruger LCP and the Taurus TCP, which match each other so closely that, as one poster on Imgur found out, the Ruger’s slide will fit on the Taurus’s frame:


He calls this combination a “Rugaurus”. Personally, I prefer “Rugersaurus”. Image source:

Not only that, but this Frankensteinian gun will apparently function… Some of the time, anyway:


Many gun companies talk about their designs as being “hybrids” of other designs… But I don’t think this is what they mean, exactly. Image source:

Neither gun is a copy of the other, in fact, but their parts interchange in this way because both are a copy of the same pattern by a third manufacturer: The Kel-Tec P3AT.

    ARuger frame on a Taurus Slide.. I have not always been a proponent of Ruger ( I.E. when Bill Ruger lost his marbles and sided with the hoplophobes) but WOW this is literally a case of tossing pears to swine. it’s FUGLY it was never intended to be yet it live..good on ya , though I have to kinda question why ?

    • Andrew

      At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul.

      • Wizard_of_odd

        Wow, little hostile there. Might want to switch to decaf.

        And quoting an Adam Sandler movie.. What part did I lose you at ?, because I’ll be more than happy to simplify it for you.

        • Phillip Cooper

          There’s this thing called punctuation. You might want to look into learning to use it.. PROPERLY.

          • ostiariusalpha

            Those double period ellipses have no place in English grammar, and the commas just seem to come and go as they please. Otherwise, I’ve seen worse displays of punctuational ineptitude.

      • ClintTorres

        Dude, this is the comments section…where random thoughts are supposed to go. Who died and made you Comments Czar?

        • Bill

          Random thoughts are what schizophrenics have. Poor writing skills, while epidemic, still reflect on the writer and his or her credibility. Would you respect the opinion of a person who was a poor shot or lousy weapons handler when it came to a firearms issue?

          • ClintTorres

            Do you have to be credible to make a comment? The reason the comments section exists is to capture the diverse thoughts of the readers. Despite the lack of proper punctuation in Wizard’s comments, it was pretty easy for me to digest the point of his comments which are salient to the article/post. Man you guys are uptight!!

          • Bill

            “Do you have to be credible to make a comment?”

            You actually typed that out loud? I suppose you doest have to be credible to make a comment, Donald Trump proves that every day, and for sure the signal-to-noise ratio on the internet is way out of balance, but credibility really, really, really, really, really, really, yeah, really means a lot.

            Maybe “we” aren’t too uptight, maybe “you” are too willing to accept mediocrity. A person can be the smartest, most knowledgeable in the world, but if they can’t express themselves well, it’s just wasted.

          • ClintTorres

            You know, you have the freedom to ignore comments you don’t find interesting or “credible”. Maybe someone else will find something funny, amusing or interesting in something you don’t. But I guess you’ve already decided what is good for all the rest of us.

          • Bill

            Congratulations for your firm stand on the virtues of ineptitude. It takes real guts to defend error. I didn’t decide that proper grammar was good for everyone; thousand of grammarians did. But stand tall and let your wrong flag wave. When a clerk gives you the incorrect change and shorts you some money, hey, it’s just basic arithmetic, he should have the right to get it wrong, correct?

          • ClintTorres

            I think you missed the point. I’m not extolling the virtues ineptitude. I’m deriding pedantry.

          • Bill

            If people believe that correct grammar is pedantic, no wonder American society teeters on the brink of illiteracy. If you’re OK with that, you loose the moral authority to point out that a magazine is not a clip, a revolver is not a pistol, shotguns don’t knock people backwards, or any of the thousands of other inaccuracies that plague the field of firearms. After all, aren’t they minor?

          • ClintTorres

            You used the word “loose” incorrectly so your entire argument has been rendered moot…by your own admission.

          • Bill

            OK, I made an error that passed my proofing. I haven’t lost anything; autocorrect causes as many problems as it fixes. If you’re comfy with sloppy writing, you ought to be very happy, as you’ll find plenty of it. Enjoy being a member of the vast army of the mediocre.

            Are you this casual about shooting? Hey, if it hits the paper, it’s good enough, accuracy only matters in formal things like the Olympics?

          • ostiariusalpha

            Hmm … “typed that out loud” … now that is an odd phrase.

          • *opens door*

            *freezes, stares for several seconds of awkward silence*

            “Uh… I… Was just going…”

          • Bill

            I’m a 30 year cop. I’ve deciphered the reports that cops write, or at least attempt to write, and watched them get shredded on the witness stand because they could not construct a sentence properly.

            I send my random thoughts to my Happy Place.

        Sieg Heil!!!

  • thedonn007

    I have a P3AT and a TCP. I will have to try this lster today. I do know that the P3AT and TCP mags interchange. I have actually ben thinking about getting a LCP due the to the better sights.

    • kipy

      I carry a Sig P238 everyday, you might want to make it 4 380s in the collection πŸ™‚

      • BearSlayer338

        Or just get a Sig P938,slightly larger than the P238(I have both) to the point that they fit in the same holsters.The P938 gets carried,the.380 gets left at home or is used for backup.The P938 is 9mm +P rated and if my life is in danger I rather have a 9mm +P to defend myself with.(Ranger T’s)

    • Kefefs

      I couldn’t get the LCP magazines to work in the TCP. This setup (LCP slide, TCP frame and magazine) was the only way it functionedor fit together for me.

  • M.M.D.C.

    Been done befo. The “Cougar”

    • Giolli Joker

      Thanks for heightening the beauty content of this page with a Bowen’s creation.

      • M.M.D.C.

        It is a handsome gun.

        • Giolli Joker

          As everything from Hamilton Bowen, indeed.

    • Renegade

      I really wish Ruger made the .45 Colt/ACP version with a longer barrel.

      • M.M.D.C.

        I agree. This is a good excuse to compare the original with the hybrid above. It’s interesting to note how much better the Redhawk looks with a little more contour milled into the barrel and underlug.

    • Anonymoose

      I want one of those in .454.

  • M@

    While that may be true, Ruger still has a waaaay better track record of quality products, unlike Taurus.

    Never had this happen with a Ruger…

    • Paul White

      my younger brother had to send back a 10/22 that wouldn’t rotate the little rotary magazine

      • Just say’n

        Dose anyone use the 10 round rotary mags that come with a 10/22? I thought those were immediately tossed and replaced with a Butler Creek 30 round mag or something more appropriate.

        • Bart

          There are benefits to the flush mount of the 10 rounders. The 10 rounders are also generally regarded as more reliable than the Butler Creek mags.
          I’m not even a 10/22 owner, but the above comments are the “word on the street”. Personally, I am more a fan of the Marlin 60 and 795 – cause I’m cheap – and cause they work well.

          • iksnilol

            I prefer the Marlins as well. Half the price, twice the accuracy.

          • spasmonaut

            I only use the factory 10-round rotaries. I have no desire to use extended magazines that aren’t flush.

        • ostiariusalpha

          I do, they’re extremely compact and convenient when all you want is 10 rounds. I have the banana mags also, but not the Butler Creek junk.

        • I use them a lot. When I am walking around squirrel hunting, having a flush fitting magazine is nice.

        • Hugo Stiglitz

          Not in NY! That would make it an assault weapon according to the dictators who run the state.

        • David Underhill

          Yes, here in australia we do use them a lot. Main reason is 10 round limit imposed by government. There are even 10 round versions of the ruger bx-25 mag sold so the tacticool brigade using the ruger charger can look “KOOL”.

      • ostiariusalpha

        Wait, he had to send back the entire rifle because the little magazine was defective? That doesn’t make a whole lot of sense. Just buy another magazine and get a refund for the old one, the gun doesn’t operate the magazine’s follower in any way on a 10/22.

        • Paul White

          He just did what Ruger told him to. I know nothing about the design of the gun so I can’t even speculate what would cause it

  • JamesRPatrick

    I read that Kel-Tec never bothered to patent that gun.

  • J-

    So it’s as reliable as the Taurus on its own

  • robo kruck

    Going back to Big Bill himself, he copied what ever. But he made it better. He is gone and now Ruger just copies. They should owe Kel Tec half for all that they have stolen from them.

    • Matt

      Except they make better versions that actually work, rather than junk swathed in polymer, like Kel-Tec?

      • L. Roger Rich

        LOL..Matt the Rugers are polymer too…

    • Bill

      Like the Mini-14?

  • Will

    The Glock and Smith & Wesson interchangeability.
    Glock 17 and S&W Sigma slides and frames were interchangeable when the Sigma first appeared on the market.
    HUGE law suit ensued. Glock lost because the only thing they patented was their “Glock Safe” trigger. Flocks arrogance and S&Ws willingness to pirate a better design cost Glock a fortune. Such a shame.
    S&W should have stuck to what they were good at.nrevolvers.

    • Curious_G

      Was going to mention this. The author suggests the M&P is a copy and it is definitely not. Being plastic does not make it a clone.

      • And if it did, that would mean the Glock is a clone of an HK pistol… πŸ˜‰

  • floppyscience

    Wow, never expected to wake up and see my little experiment on TFB. Thanks. πŸ™‚

  • Machinegunnertim

    Ya, what the hell!? Glock is not the originator of anything nor is it the best.

  • L. Roger Rich

    Never saw any poo on any of my KelTec. The all work well including my KSG and my 2000. Why do find poo on guns Matt?

    • Matt

      I don’t think you took the time to read what I typed.

  • L. Roger Rich

    I have a great KSG. Never skips a beat.
