Anyone of you blasphemous glockers want to share their experience with the OT defense gripfix hump remover?

I love the simplicity and reliability. The finger groves or goalpost sights don’t bother me.

What my smooth brain cannot cope with is the hump. So I’ve kicked around the idea of either sending my 4 glocks out for service, or the gripfix.

Leaning towards the DIY gripfix.

OT defense gripfix hump remover

The theory is sound, but this isn't for the faint of heart. Doing grip reductions isn't rocket science by any means, but creating a nice looking finished product takes work, expertise, and experience. There are some little idiosyncrasy of the reduction process that only comes with the experience of dealing with different polymers and even different production years of the same glock pistols, IE Gen 2 polymer reacts slightly different than Gen 5 polymer.

I have quite a few experimental frames, that were used to get my process down. Most folks don't have those types of resources. This plays like a one and done kind of deal. I would at the least advised people to practice their texturing techniques before committing to this type of project.

I'm also a bit weary of cutting and gluing parts back together.

I don't mean to sound like I am trying to sell you or anyone on sending it to someone who does reductions, but you have to understand that shops that do reductions have tested their process for strength durability and possible failure rates, or at least they should have. This is putting the entire process in the hands of the consumer, start to finish.

I built several test guns 2007/2008 and they spent time at local ranges as rentals. This way they were handled by different people under different conditions. My test guns were in service for no less than two years and 10k rounds. There were no failures of those test guns as far as the reduction process or the texturing during that time.

I agree completely. I’ve played around with a gen 2 to scrap frame. I put a slit in the back and heated it to reform the hump like an HK.

It works, but am hesitant to perform this reconstruction on the fleet.

What are your thoughts about heating the back strap up and molding it to form more of an apex?

I’ve done a couple. Pretty easy job.

Those are ugly as sin... And I DO NOT mean @Thomas Kelly your actual work. Your work is consistent and pretty darn nice. I just can't wrap my mind around Glocks looking like that.

Again, your work on those two is nice. I'm just referring to how odd Glocks look without their signature lines and curves.

Glocks are ugly regardless…. Now they just point like they should rather than “nose up”.

 

[PilatusTurbo]

I don't find them to be ugly naturally; to each their own is as true with firearms as just about anything else. I think that even though the grip hump may not help some, removing it just makes them look weird, to me. Again, not a criticism of your work or Glocks, just that look.

Sorry, back to OP Topic.

I need to go back and find all the pics of the process, but these are a few I’ve still got on my phone. The end result is the same grip angle as the P80 frames for reference, without the issues that come with a P80. But I’m not sure how so many have issues with P80 frames given that you’re provided a jig and bits with the kit, and it’s a simple and straightforward process to complete them.

After the hump removal, what is the circumference of the base of the grip?

P80- there can be a number of issues with an 80% frame’s function. It took me some tinkering to get mine “reliable”. Even then it’s not as smooth as an oem Glock. And that’s sayin’ something. The phrase “your results may vary” could not be more true.

Taking a reliable platform and improving personal egros is ideal rather than finding another brand or “just deal with it.

The circumference is roughly the same as a P80

 

[Dbltap22]

Interesting. I measured my p80, gen3 and gen4 19's. they all come out to 6"

That Gen 3 34 had an obnoxious hump. They lessened the hump on the Gen 4 with the incorporation of backstraps.

I could see that. I have a 34.3. I chopped the grip so it works with all my mags. Part of the hump was eliminated, but still there. I also cut a slit in the heal, heated it up and pressed the two ends together. Going for the taper effect. But that polymer is very thick there. I really wanted to return to its original shape.

Removing the hump is what makes the difference in how the grip feels. The hump just hits most folks in the wrong spot, causing the Glock to point high, or just feel off. Reducing the circumference of the grip is just a by product of getting rid of the hump.

It’s no different than the finger grooves. Some hate ‘em, some like ‘em. I don’t mind them. They provide Extra leverage. But that flipping hump! LOL. I modified my grip (rotated forward) so it doesn’t press in the meat. Maybe that’s what people do naturally that say it’s no big deal.

BUT, BUT, BUT....pointing high fixes the shooting low, so all they ("most folks") have to do is move the rear sight to the R.

One can always use the 1911 grip safety argument - "if you can't hit the grip safety correctly, you are gripping the gun wrong." In this case, if you mind the hump, you are gripping it wrong. 😂

Guess I do everything wrong since I pin my grip safeties too

 

[Dbltap22]

GripFix’ed my first child.

Mad scientist alert.

I designated my 34/35 for the first tumor resection surgery. I had already chopped the grip years back. So why not?

Before I finish it off and add texture, I wrapped it in goon tape to test ‘er out and see if it’s something I’m going to continue on some others. I’m looking at you gen 3. .

Feels good so far.

And you would right about both guns.
