    The only part of the Glock grip frame being used is the grip area, the upper part of the frame has to be cut off, destroying the handgun receiver. Only 1 gun.

    I havenít done anything with it. I think Iíd rather have one fabricated from sheet steel and welded on like the stock grip.
    Their steel lowers are not designed to use removable grips, AFAIK. It simply will not bolt up. Additionally, the aluminum lower might have slightly different dimensions. It may not be as simple as just bolting this grip on, it might need a spacer or some other mod.

    Thanks for the clarification.

    The initial model released with the Glock lower was a steel frame and a bolt on aluminum grip. They later changed it to an aluminum frame. The one I bought 3 years ago is for the steel frame. Thatís what I specifically asked them for as the aluminum frames were already out at the time. Once you get yours, we can compare dimensions and see what the differences are (assuming the text on their site is correct and that they sent me the correct grip for the steel frame).

    Oh, I see. That would be useful. Thanks.

    It's a Magwell not a frame.

    I spoke (wrote?) out of ignorance; I didn't realize that by cutting off part of the registered part rendered it a non-firearm.

    Hey, so not to beat a dead horse here; however, I think that something like this is possible if I can dig up the old DIY Iron Glock files. The Iron Glock was the original Glock 80% receiver and you had to modify old airsoft frames for aftermarket upgrades for the Tokyo Marui guns, if anyone is familiar with that airsoft brand. You would use after Guarder Glock frames which even to this day are some of the best after market ones on the market. I digress, though.



    What I'm thinking is, because I would personally like this more than Grease Gun mags for my OBS SM10, I could probably modify the DIY Iron Glock kits for the 21 to the most vertical grip angle. Or the other option being would be to get a 3D .stl or .sldprt file, and modify it to the point we could have someone do an SLS manufacturing for the grip and make it a Gen. 5 style.



    All of these are possible and it would mean that Glock 17, 19, 21, and 42 (.380 ACP) magazines.

    I bought the MPA Glock grip and made some measurements. As far as I can see, the Glock mags/grip could work very well for 9mm on the M11/9 and M11/380s. I'm pretty sure the 9mm Glock mags could also use 380 ammo too, but the distance from the feed lips to the chamber is similar to using ZMAGS. The Glock mags would work... just not as reliable as the small metal mags. I would be concerned that the CFW bolt would have similar feed problems with the slower rate of fire.

    I am still very interested in this conversion but for me, I would want multiple, easy to attach, grips for various combinations. Something like the way an Uzi grip fit on to the receiver.

    1. Large OEM 9mm grip, for 9mm and Lage 22 mags
    2. Small 380 mag grip
    3. Glock mag grip
    4. AR or AK grip

    Okay, so this has actually garnered an interest. I'm going to download an M10/45 file and then use a 3D G21 file. I'm going to match the G21 feed angle to the grease Gun feed angle. I'll plot this out in Solid works. I can have this done tonight if I had the time.


    I can then 3D Metal print this out of 17-4 Stainless steel so it can be welded to the frame with ER3O9LSi. You wouldn't have to worry about post heat treating either.

    Big140 can you show a vid of how you're attaching the MPA grip? Have you actually chopped a transferable?

    I have not, I was considering my options. I plan on it and I'll post about it if I do.

    Hello,

    The gun on the plywood backing is actually my gun!

    The grip is indeed correctly identified as being from a steel CCF race frame. CCF made very few frames, of those made the vast majority were aluminum. The steel CCF race frames are absolutely ridiculously rare. It took me over a decade of looking to get one, and it was expensive, especially as it had to be canabalized from somebodies pride and joy "racegun". Then I sent it off to Len Savage. The CCF race frame is indeed destroyed, as far as being a gun, in the process, you are truly just cutting off the grip portion and welding that onto the M11 frame (of course it is not that simple, mag height, feeding etc.). BTW I was also able, all those years ago, to contact the former owner of CCF and ask him if he had one still laying around even if it was a defective one that he might be keeping as a memento or paper weight and he hooked me up. I got the last one!

    I am currently getting ready to send an M11A1 380 off to Len for the Glock grip conversion (using that piece I got from the owner of CCF) and conversion to 9mm with tungsten bolt so I can have something much more compact. It should have a cyclic rate of around 1,000 which I am totally fine with (I've got training time on the mini-uzi and a factory Glock 18C as well).

    I suppose other smiths could do it (I would try practical solutions if I didn't use Len Savage) but I went with Len Savage because he had done it before. There are I think maybe 4 or 5 total out there like mine. Not sure if they are transferables like mine.

    With a CFW tungsten bolt in that thing, I would put it up against an MP5 any day for shootability or controllability and accuracy in burst (still can't compete with that closed bolt semi accuracy). I say that advisedly as someone with a fair bit of formal MP5 training and according to Anchorage Police SWAT standards (I've never been a cop but my instructor for a couple of the MP5 classes used to run APD SWAT and taught class accordingly). That was a lifetime ago!

    Best wishes to everyone and a Happy New Year.

    Thanks for replying TED. I look forward to seeing pictures or video the M11A1 Glock grip conversion. After shooting about 2K rounds through a OEM G18, I wanted my own micro select fire pistol and this seemed to be the way to go. I too bought a SS CCF race frame after talking to Len Savange. I purchased the grip from the owner of CCF that was copped for the project. In the end, I did not go through with it as I wanted the option for multiple grip combos. Here is pics of the SS grip that I purchased from CCF.

    Personally I think there are those that want a multi grip modification. But it certainly seems to me that some type of structure needs to be added to the receiver to make up for the loss of structure of the welded in magwell/grip. Since we are talking about the registered part, I would think that such a modification would need to be throughly engineered and tested. And there is the rub. Such development would not be cheap. How many owners would be willing to pay how much for such a modification? Would an 07/02 be able to make a profit after the time and resources spent in development and application? If only five owners or even 50 owners would want such a modification, would be a very different price structure than 500 owners wanting such a modification. This is just my opinion.
