Gamo Gamo Urban - Gritty trigger after trigger screw mod UPDATE: Charlie Trigger is aweome!

[WIndOnYerGrape]

Edit: See bottom post for the fix!

Hello all.

Got a gamo urban and used the barrel band screw , to replace the trigger screw.

The trigger is now very crisp and light with a tiny bit of creep.

The problem is the tiny bit of creep is "sticky" or "gritty".

If I pull the trigger, and let off before the break....it will stick in that position.

What do I need to do? Any help is appreciated. Thanks AGN.

I did mine years ago but if you search there is a video about polishing the housing on the Gamo trigger. Super easy.

Did you polish the screw end on the new screw? If no chuck it up in a drill press or hand drill and smooth it out.

 

[WIndOnYerGrape]

No I didnt, great idea and make sense. I really appreciate the help!

The Charlie Tuna trigger fits right in and is a huge improvement.

 

[WIndOnYerGrape]

Interesting, I just submitted my order. Website looks like its from 1995

Im assuming this eliminates the screw in the back? Ill watch the install vids later.

Thanks for the heads up.

You no longer will need to repurpose the barrel band screw. The trigger is a drop in and it is a perfect fit. It should come with the needed bearing. The trigger pull goes from being so so to being excellent.

The website is an antique but the lady is super nice and will get your trigger out to you. Patience grasshopper .

I did the Charlie Da Tuna trigger to my Urban, it made it a single stage,,, that fixed the creepy vague trigger pull
I like it a lot better than factory

Trigger showed up today. Very high quality unit and worth every penny.

Super easy install. Very happy with it.

Thanks guys.

I gotta say this urban is pretty dang sweet. Added pic rail, sling mounts and single shot tray.

Got it cheap second hand and its really surpassing my expectations.

Not regulated, but its right up there with the notos as far as "bang for the buck". Really great budget option.

So did you guys order the "GRT-4G" model number from Charlie? Seems like a nice upgrade.

 

[WIndOnYerGrape]

Yep GRT-4G. Craftsmanship is top notch and the price is right IMO.

You do have to remove the trigger group from the urban to get the plastic trigger plate off.

It looks like the plate will just come off, but it will not come off without removing the trigger group. (very easy, just an extra step compared to some gamos)

Just encase anyone in the future sees this and cant figure out why the plate isnt just coming right off after removing the action from the stock.

Cool thanks for the info. Just ordered a Coyote from Gamo for uber cheap and would like to try out the Charlie Tuna trigger.

 

[WIndOnYerGrape]

Awesome, I think you're gonna like it!

If you have any trouble with the trigger, just holler.

Pretty straight forward install tho!

I had the CDT trigger on my previous Urban and it was wonderful. My new/used one feels acceptable so far but I may have to do the CDT trigger again.

 

[Deleted member 58271]

When I first installed my CDT trigger there wasn't a huge improvement. The magic happened when I went back and CAREFULLY used the supplemental instructions to adjust it.

My Urban lost the pickle a long time ago. I use a DFL when I need quiet. I sleeved the barrel with a snug fit carbon tube to further stiffen it. Also some porting and clean up.




I can run it up to about 30 fpe with the JSB 18s but it is happiest around 26 fpe. The JSB 18s and Hades shoot fantastic, the CPHP are okay.

So is that a Donny Tatsu and which pic rail adapter is that? Looks nice and low.

I use a Tatsu or a Tanto typically. When I use my Jeep as a rolling blind I go bare.

The pic rail was from the "The Country Store" in Britain but I think this is it here:

Picatinny Rail - Gamo

www.gamo.com

The rail does not run full length but it works great and fits nice.

The barrel adapter was from eBay and I bonded it on after careful alignment. The carbon fiber sleeve was Amazon.

Edit to add, there is all sorts of mayhem on the internet about removing the pickle. I removed the barrel from the rifle and put it in a wooden vise. I got out my propane torch and burned it off. The heat did not hurt the barrel or finish. I used a thick pair of welding gloves and after sufficinet heat and burning of the hated plastic pickle, grabbed a hold of it and pulled it off. What is left under the now gone pickle is quite ugly thus the need of an adapter and possibly a carbon fiber sleeve. Do not cut the barrel down. The barrel has a choke in the end and is on the short side already.
