Trigger Mod Differences

I found three different trigger mods around:

1) Charlie's GRT
2) PSP's Micro GTX
3) Rich's Mini II

It seems that the GRT is significantly more expensive than the other two. What makes it superior?

For all the different mods, do they require removing the stock and taking out the anti bear trap device?

Thanks.

I believe comfort makes the GRT the best. It's also not just a mod, its a whole new trigger. Feels totally different than the stock gamo trigger.  I will be posting a full review really soon, but lemme tell ya, you won't go wrong with the GRT trigger

I don't know about the bear trap, but I'm sure someone here will.

Trigger mods seem to be a controversial topic on some forums.  I bought the tuna trigger for my Gamo 440.  I am very pleased.  Even though it is higher, if I ever get another gun, I'll get another tuna trigger for it.  If it were in Consumer Reports, it would be a solid red dot!

None of them require removal of the anti-beartrap linkage.  As Randy said, the GRT III is a drop-in trigger replacement, instead of a modification inserted in the stock trigger.  I've heard 1 report of Rich's insert getting erratic after several thousand shots.  That person replaced it with a GRT.  I've heard no negative reports on the PSP insert, but I find that a little suspect in itself.  Negative comments about it would be construed as counter to Yellow forum policy, and would therefore be likely to disappear :-)!

Installation of the GRT is a snap, as long as you don't drop any small parts, it's a 15 min. job.  And it usually works really well as it comes, no adjustment needed.  The installation of the insert is more involved, and can sometimes require additional modifications.

I have no personal experience with the inserts, but I've installed 4 or 5 GRT's.  One of those is in a CFX that has around 20,000 pellets through it, and still shoots great.  Randy's right, the feel of the GRT is far superior to the stock Gamo trigger, and it looks pretty nice too.  Functionally, I don't think there's a lot of difference between the 3, but the GRT is one very nicely machined part, the others are multiple parts that still utilize the stock trigger, a less than great piece to start with.  I know the choice I'd make, I've made it several times already.  BTW, welcome to the Gateway!

Both the improved trigger pull and ergonomics (as well as the manufacturing process) are the big differenceand that certainly does help in the improvementof both accuracy and consistency.

There are a couple ofguys out there on another forum that say the ergonomics factor doesn't matter.... but......, those that own the GRT-III know the difference.I get e-mails from customers around the worldeveryday as well as comments on different website's, some of which are posted on the testimonial pageon my website (can't post them all) that will attest to the GRT-III trigger and the difference and improvements that it makes.

Just installed mine in my Gamo 440 this morning.  Drop in fit and without any adjustments feels just right.  Its a machined part and even with modern CNC equipment it still involves many separate operations to make.  I have conventional machine tools but items like the GRT-III trigger or Mac1 solid lever are a steal in comparison to making them yourself.

Hello Stilte,

WELCOME TO THE G.T.A. Forums !!! This is a GREAT PLACE TO BE !!!!

I have been shooting for over fifty years, and I can say without reservation, that the GRT-III Trigger is without equal for cost and functionality. This has been the best money that I have ever spent, ever. If I had spent twice the moneyfor the GRT-III, I would have been VERY HAPPY !

This sounds like a sales pitch, but ounce you have yours, you will feel the same way about this trigger, I GUARENTEE ! It's just SUPER !

One big difference is the installation. The GRT pops in real easy, the insert (at least Rich's) takes more effort and likely requires some hand fitting. If you're doing one and you're a smidgen tool shy, the entire trigger replacement is far and away the least painful.

Personally, I've got a volume issue! I'm looking to do 6-7 guns, so I'm almost certainly gonna go with the inserts. As for ergonomics, maybe the stock blade doesn't have the best shape in the world, but the feel of the trigger pull is improved so much that to me, it doesn't really matter.

I have three CDT triggers, one of the prior model and two of the latest model. I would give them the thumbs up. If you get a CDT tune, he puts in the trigger for free and discounts the trigger itself, this is the way to go by my book. I am giving a newstock  .22 Gamo CFX a few break in tins and it is a dog and a half compared to my CDT tuned .177 CFX with GRT trigger. My #1 game getter is a Gamo 440 with CDT tune/trigger and I shoot it with open sights at 35-40 yards almost every day. If I do my part, it does the rest. By the way, a budget scope/mount/ring set will cost you $100-200 and will not help one bit if you have a bad trigger. Hope this helps.

Well I might as well put in my 13 cents worth.. I agree with everyone except Vince.. But Vince dances a different tune than I do.. hehe. I have 13 Gamo's and I invested in 13 GRT-III triggers, and like Bob said above, you can buy a $100.00 scope, rings and a high end shooting table but it won't make as much difference in your accuracy, as CDT GRT-III trigger does. Nicecrisp release and you can adjust it to where ever you want. Thats my opinion Gene

Yup, can't beat the DA TUNA trigger. I have one in my Gamo Hunter 220.22 , it's truly a supurb trigger.Ed

I have the GRT trigger from the tuna and it is great, worth the difference. Feels like a match trigger, I did adjust mine a little and I do mean a little, but that is why I bought an adjustable trigger. John

Thank you all for the replies and warm welcome.

It seems that the GRT trigger is very highly recommended.

From what I understand, the GRT trigger is a whole new trigger that feels good and pulls nicely. Whereas the others are add-ons to the original trigger that improve the trigger pull.

Could someone please give me a quick run through on how to replace the trigger with the GRT? I am quite new to modding and feel a little nervous about playing with the insides of my gun.

Personally, I think the stock trigger feels fine, not fantastic, but decent enough, the main problem is knowing where the break point is. It wil probably come down to how easy is it to put the mod in, and I wouldn't mind paying a little more if it means not having to fumble around for hours with parts.

Send me an e-mail at     CDT2@Charter.net    and I'll e-mail you the instructions, both pictorial as well as written. It's very simple to do and can be done in 15 minutes or less if you are just a little handy with  a screwdriver.

The trigger is very easy to replace, and you are NOT going very deep into your gun to install the trigger. Like I said, if you get a bit nervous about this sort of thing then the entire trigger replacement is the way to go... don't get into the inserts.
