    Will a Ruger P89 Slide and barrel fit on a Ruger P90 Frame? or Vise Versa? How about a P94/944 (40 S&W) will that slide onto either of the other frames or vise versa?

    Taking into account the same decocker and saftey setup. (e.g. a P89DC on a P90DC, or just the P89 DA on P90 DA).

    I have yet to find a definitive answer. I have a Taurus PT-92 and a Taurus PT-100 and can swap slides around and easily go from 9mm to 40 and back, just swapping my slide, barrel, and magazine.

    Could I go from 9mm to 45, and 40 or any combination in the Ruger platform?

    If it does not work simply because the magazines don't work that's fine, I can fix that.

    Thoughts anyone?

    Before anyone can answer, we would like to get to know you.
    How about stopping in the "Introductions" area.

    We do not know your experience and are hesitant to say "yes" or "no".

    Have you personally tried it?

    They won't interchange to the best of my knowledge. I don't understand why you would want to in the 1st place as Ruger don't offer conversion kits anyway. If you have the slide/mag/barrel then you also have the frame.

    Made intro, and more information

    Well hello danf_fl. I did as suggested and posted an introduction. To re-iterate a little bit, I reload and am accustomed to paying attention to detail. No, I have not personally tried it. That's why I posted the question.

    stalkingbear: Taurus (or Beretta for that matter) doesn't make reference to swapping either, but I do it. I even have the 22 Taurus conversion kit. When I called their support, the gal I talked to had no clue that they even made such a thing. So the "Ruger don't offer conversion kits anyway" doesn't mean a whole lot. I just want to be able to do it, even if it requires a little modification. I turned my WASR 10 from a single stack to a double stack and it works beautifully.

    I have purchased a slide, barrel, and magazine without having the frame, so yes that's possible.

    I apologize if this might come off a little curt to anyone. I was looking for something constructive vs negative of "I don't understand why you would want to in the 1st place". A definitive answer like "On the Taurus PT-92, the slide catch does not protrude out enough to catch the PT-100/101 slide, and the replacing the 92 slide catch with the 100/101 and it works perfectly, but you will have slight problems just doing the top end ONLY." (for example) is a much more constructive answer.

    Regarding that, if someone only has one of the pistols in question (Ruger P Series), if they could run their caliper over the critical areas, it would greatly enhance my education, and likely the responses in this thread. Thank you.

    Have you looked at any 1911's? Those are begging to be modified to your personal firearm.

    I have an old P-85 and will check the dimensions in the next day or 2. I just got back from watching freestyle monster jam and am too tired tonight.

    I have a P944 that I can take measurements from, if you tell me what it is you want. I've also wondered if this is possible, as the wifey has a P95 (which I don't care for) and wondered if I could swap slide/barrel/mags to my P944 frame (which I do like).

    Measurements

    I took measurements of the slide rail of my P90. I am curious to see how the P89, P94, and 944 "measures up". What I found is that the slide rails are roughly .746 Inches or 18.94mm although this might be off a little.

    You're right. They won't interchange.

    WHY won't they interchange? Are the measurements drastically different? Is the slide too long/short? Too thin/wide? What?

    AT best, you get some 40 conversions down to 9mm. And, some 40 owners get conversion barrels to go from 40 to 357 sig, depending on the brand of gun and availability of the barrel.

    You will not get a 9mm/40 to up convert to a 45. Not gonna happen. Slide, barrel and frame all have different dimensions. The body of the frame (grip) will also be bigger on a 45 caliber of the same gun model. Go look at some 9mms and 45 ACP models of the exact same model (like an HK UCP9 and HK USPc45). Not the same size grip.

    EVen a 1911 in various calibers typically cannot just covert like that with a simple change of the slide. Ejectors, extractors, feed ramps, etc... All are slightly different in various calibers

    I'm persistent

    I now have a P90 (45ACP) that I can convert to fully functioning P91 (40 S&W) with just a slide swap, and am looking to extending this further to a P89. (9mm).

    This was done without any positive input to this thread. I figured out how to do it myself.

    To those negative posters here, if you don't have anything positive to contribute, then you should not be replying to people only to disparage them for their innovation. Whether it is guns or any myriad of subjects.

    Why don't you call Ruger? Technicians at the Prescott, AZ plant are experts in these matters. If it is a drop in conversion they will tell you the truth and order the parts for you. Calling Prescott is lot simpler than going through all of this guessing.

    P89/P85 slide swap

    I can't speak to wether the previously mentioned models can be swapped with or without modification. But I do know that the P89 slide can be swapped out for a P85 slide if required. I have personally modified the P85 slide to work with the P89 frame. My P89 came with the stainless slide and I'm not a very big fan of the two tone look. Since stainless is so notoriously difficult to darken, I decided to simply replace the slide. I found a blued P85 slide being sold at online auction for next to nothing and decided I would purchase it just to see how much modification would be required to swap the slides. It turned out to be easy. The only modification required was that the grove on the underside of the slide needs to be ground down or milled just behind the detent, and the opposite side grove may need to be widened just a tiny a bit, if at all.

    The modification only took 15minutes to complete using a dremel and jeweler's file set. The key is to remove small amounts of material at a time. Frequently dry fitting to ensure that you don't remove too much material. After applying cold blue to the newly exposed metals, you can hardly tell that any modifications were done. Works just as well as my P89 slide and looks great.

    I'm in no way a professional gunsmith, but I have built countless custom 1911s. As well as other firearms for my own person use. This type of modification carries a great deal of risk as any modification to any firearm can cause any number of dangerous or leathal failures during firing if the modification isn't performed correctly. If you are not confident in your abilities as a gunsmith, this mod should not be performed. If you decide to attempt this mod, do so at your own risk. Lol.

    I hope this helps. And I apologize if this post violates any forum etiquette. This is my first post and I'm learning as I go.


    Thanks and enjoy.
