Can a broken part be fixed with epoxy

[blume357]

I have a number of Poly guns. In fact my Sig P320 is sitting on my desk right now fully loaded with one in the chamber still waiting to go off.
But I'm pretty much a metal frame semi-auto guy.... I like the way it feels and I'm just old school I guess...also a DA/SA decock only fanatic

Got her shipped off today. Guy at FEDEX was great. That has become a huge business.

THANKS ALL FOR YOUR HELP.

Polymers, many of them anyway, are notoriously hard to glue. I'm guessing the piece in question is injection-molded glass-filled polyurethane - used in many Ruger firearms. I doubt epoxy would bond to it. You can try, mold the repair up and let it cure. Testing the repair with your fingers. If it passes that test, try to drill it. May end up scouring ebay for your parts though.

Might try drilling an off angle hole and inserting a piece of proper diameter wire to create a mechanical lock for the glued epoxy repair. This done frequently when glass bedding an injection molded rifle stock.

good luck. Please let us know how it worked out

Great advice. Thanks. The only problem is my proven track record. I have this special kind of propensity to destroy everything I try to salvage.

As many suggested, Ruger cannot fix my gun but offered me the opportunity to buy at a discount something fairly comparable. So, I'm asking for your recommendations if you have a minute. I'd appreciate your input.
Just a note: I have exceptionally large hands. Sounds funny, I know, but I liked the P95 in part because it fit pretty well with only a small portion of my hand extending below the base of the grip, grasping nothing. (Gloves never fit)

Thanks

RXM or GP100 ( 3 inch ).

With the info from Ruger (what they are offering) go to a gun shop and try some on for size. Costs nothing to touch guns. Then you will know what feels right to you.

 

[eveled]

RXM or Security nine. Are the closest to what you have.

Here is a comparison of their dimensions.

The RXM is modular and Striker fired.

The Security nine has an internal hammer.

"Polymers and composites stronger than steel are increasingly used in NASCAR vehicles to enhance performance and safety"

I think that kind of common and generalized evaluation influenced me over the years to trust plastic parts for some applications. I hadn't considered how brittleness may play a role over time.

Actually, plastic parts are not stronger than steel parts. Not size for size anyway...Maybe pound for pound, but how massive would a pistol frame have to be for that?.....You do realize that this whole thread centers around a broken plastic part that someone wants to glue back together?...LOL...I mean really, think about that.

A corner of plastic broke off that holds my ejector pin in place. I have a P95 and forgot to lower the ejector after cleaning it. That's when I broke it, I guess. Can I rebuild that little area with epoxy and drill a hole in it to accept the pin? Do you think it would remain in place on the polymer with enough strength to work?

In my experience the epoxy will not hold for long. It might for a few rounds, but do not trust it with your life.

I have had amazing luck using JB Weld. Prep and enough cure time is the key. It has held threads and withstood recoil

Epoxy, JB weld, is good stuff used in the right place. Eventually, sooner or later it will fail under recoil.

not an expert on the topic but have built a few boats using epoxy and have more than a few hours using different types

your question is probably more complex than it might seem
the best answer I could offer is "maybe"
the bond strength is greatly dependent on the type of plastic being repaired - I dont know anything about the type of plastic used in the those pistols, but I would GUESS that they are not conducive to making a good bond

if you try it, surface preparation is critical - you are making a mechanical rather than chemical bond so both surfaces have to be rough - I cant visualize the repair you need to make but a cross pin installed in a hole drilled through the mating surfaces is a common method to strengthen a repair - may not apply to your situation

also, selecting a quality epoxy is important - Devcon comes to mind but there are other options - you can use aluminum additives (or some such) for increased abrasion resistance depending on your situation

you might try asking Ruger - there may be an engineer there who knows the composition of the part in question who could recommend a compatible adhesive that they know will work

maybe more questions here than answers, but hoping something here helps

Contact Ruger. Describe issue. Even money says they replace the part. If there are any left in a 45 year old gun.

I sent the gun to them last week. They can't fix it. I'm going to get another gun from them, soon. We have to work out the details. They said they would try to help with the expense. Thanks for your interest and your help everybody. I know practically nothing about firearms, so I really appreciate everything you've done to help.

I was at HomeDepot a number of years back looking to buy a tarp... on one offered was printed on the big label, "Corners now reinforced with high strength space age polymer. " What I deduced after a moments contemplation was the bean counters at the factory figured out a way to make the cheap vinyl tarps even cheaper by replacing the metal grommets in the corners with plastic ones......

I don’t know if you’ve already chose a pistol or not but if you want a semi-auto 9mm & have large hands I believe the American full sized pistol might be the best choice. I have no idea what they would charge you but it has a full sized grip & interchangeable backstraps for the grip.

Eventually, before I kick (which is approaching rapidly btw) I'd like to own a .44 Magnum. That would be fun. Of course, I would also love to hunt grizzlies in Alaska. If I can manage to walk down the driveway and get back the same day, I'll book flight.
