Is a weighted plug legal in CO?


Recommended Posts

I shoot open so I’m not a CO rules expert. Searched and can not find anything that says no. Have a friend that is getting his new CO gun ready and asking if this plug is legal. Weighted glock plug. I feel that the answer is it is not legal but all the searching of the rules I can find say it is. Can I get a second opinion please? Thanks guys!

Yes, legal provided the following is met. The appendices for carry optics in USPSA rules (#22.2) states that an external plug that fits flush with the heel of the grip (extends no more that .10") is allowed. Plugs that extend more than that below the heel of the grip are not allowed. And, yes, the weight limit of 45 oz. including an empty mag and optic still applies (#18).

Do you know where he purchased the weighted plug?

Thanks for all the responses guys...My next question...is adding a weighted plug adding any sort of advantage or improvement? The reason I question this is if adding a weighted guide rod is a good would this plug not offset the improvement? Thanks again in advance

The idea/theory/plan is to get non-moving parts heavier. The GR and weight in the grip work in tandem.

I have the “thug plug”. I wouldn’t recommend searching lazily for that on the internet. It does feel nice but I had to take some material off of it to get the mags to drop free.

I bought 2 thug plugs-one for each CO Glock.  Both required slight filing to reduce protrusion.  Also, one fits really nice and snug, the other is a bit looser.  Neither gun was new when I installed them, so the loose tolerance may be due to the frame.  I don't notice any difference in performance, but the slight movement in one is kind of annoying.  I also have both steel and tungsten guide rods, both captured.  The slightly heavier guns seem to be a little more enjoyable to shoot, but the added weight doesn't equate to better performance on drills or stage times for me.

I used tungsten buddy, kids darby car stuff (Pinewood), and shaped it to fill the entire grip recess.  Brought the weight up from 2.4oz to 3.1oz and takes all the flex out of the grip.  I don't think it'll be easy to get out...

Does anyone know of a steel or tungsten plug that will work on the gen 4 with backstrap? The only ones I can fine only work without the backstraps.

He should skip 4 and go to 5. 4 is dead. 

I hear you. I have two gen 4s and recently heard that Glock is phasing out every Gen 4 that has a comparable Gen 5 model

I've also found you could use the flat car tire weights that come in 1/4 or 1/2 oz increments and put them in the cavity. As long as they don't show or extend below the bottom of the cavity you're good ( according to Troy). I'm going to check out the thug plug and the Carver brass insert. Unfortunately neither of them work with a backstrap but such is life

I thought they were killing all of gen 4. 

 

 

Probably the direction they want to go, but I heard only comparable models.  I'd like Glock to offer me a trade for a Gen 5 on each Gen 4 I have, lol.  Still like Gen 3 better.

If you were to add weight to the "tunnel" in the grip of the Glock, it could not extend past the heel of the butt more than the rules allow a plug to extend, i.e., 0.1 inches.
Adding the weight is not illegal, extending it too much is.

I’m all gen 5 at this point. Might be tempted in a gen 3 24 if I stumbled across one cheap

They are legal, ive been using one for years. Just make sure it doesn't protrude out. Mine did slightly, it would take a rules nazis to ding me for it so I sanded it down to fit flush.
