PMI E-Force Trigger

[procarbie]

Hey MCB,

Got kind of a dumb question for you. I got this old PMI E-force frame that’s in great condition, and I want to use it for a pistol project I’m working on. I love that it’s one of the few aluminum grip frames that PMI made (I’ve also been trying as of now unsuccessfully to get my hands on the mechanical aluminum 45 frame they made).

The trouble is that it’s a double trigger, and I find that throws off all the balance when trying to aim and fire a marker with one hand. So I want to turn it into a single trigger instead.

I thought about removing the trigger and cutting it down, but this thing really doesn’t look like it was made to be taken apart. I fear if I pull out the board and punch out the pins holding it in, that I just won’t be able to get it back together again without really messing it up.

So my question is, do you think I’d be ok if I just immobilized the action of the trigger in the frame, and very carefully tried to trim the second finger portion of it off with a dremel? I know that’s kind of the idiot way of doing it, but with a frame this old and cheap I’m just not sure it leaves me much in the way of other options.

If anyone has any experience modifying these, or just any recommendations for a gentler way to go about it, I super appreciate any guidance. Thanks!

Pull the whole thing apart to cut it....

Aluminum dust can and will short out electronic bits

I can measure and 3d print you a replacement trigger of the single finger variety if you'd like. I have one of those frames here and I know how to disassemble them without damage.

I haven't messed with the aluminium frames, but the newer composife frames weren't actually that hard to take apart. I forget exactly where (might have been under the noid) but there's a small-ish interior ledge that's held in with a pin, once you push that out it just all slides out.

Wow these are all great tips, thanks everyone!

So I will take the trigger out first then. I appreciate the offer grendal50 but I think if I can get it out cleanly then I’ll just cut the trigger itself, I do like the feel of it—it’s a nice fat piece of aluminum that fits my sausage fingers well.

Once I take the thing apart I’ll update this post with pics, try to do my part to add to the MCB compendium in case someone ever searches up how to do the same thing.

In the meantime if anyone has ever taken these frames apart and has any tips, I’m all ears!

Thanks y’all

If you have a drill press, use a drill bit punch smaller than the pin diameter to push the pin out. I use a piece of pine scrap to push the pin into. Otherwise you can use a punch with the grip frame laying on a scrap board and a hammer.

Weeell MCB, don’t be mad at me haha. Definitely not my prettiest work, but far from my worst either. I’ll prob clean it up at some point, round out the trigger a bit more. I was very diligent about the aluminum dust, confident the tape kept it out. Frame seems no worse for the wear, cycles fine.
