I have a project which has been knawing at me for almost 2 years to do!
One of the "Other Gamo's", a Daisy 120.
The little rifle is a real beauty, bought second-hand but islike brand new for all purposes.
I have shot it with & W/O scopes and it's potential is certainlly there however that trigger is brutal!
I totally love the dimensions of this rifle and it's smashing power! No chrony, but if that's 600fps, WOW!
Rather than changing sear angles, I have toyed with filing the sear's contact area length. I will not interfere with the angle this way and with some sort of trigger spring change (Lighter of course), will retain the metals hardening.
I have considered the possibility of the danger of accidental discharge too and am wondering if it's worth the try?
Any ideas?

Be careful when you do this.
If you end up going down too deep on the triggers sliding area, you lose the case-hardened layer of steel, and it can go bad
-
I agree with Ed, things can go bad in a hurry that way. What about using one of Bob's GRT III's? Will it work in a Daisy? From what I understand, the Gamo trigger design has been around for years, pretty much unchanged, and "borrowed" by other manufacturers. Based on my experience with both a GTX II and the GRT III, you just can't go wrong. Good luck, and keep us posted on the project.

Let me know if this works i have a 120 too and that trigger is a bear but the gun is a real swet heart otherwise!
Funny thing is I bought this gun on auction and shipping cost me more than the gun! I only paid $15 for the gun and shipping was almost $20!

Is that a wood stock or plastic? Looks like wood but can't tell with picture..

Thats one of the neat things about this rifle if only cost me a total of $35 and its all wood and steel. A real "steal" thanks to a basic auction and nobody elses intrest in the gun. It will be a sweet little shooter once i find some type of trigger fis that don't cost more than the gun.
-
The new Gamo trigger WON'T fit this rifle Darn-it!
I need to study this idea a little more because I know there HAS to be a "fix"!
*Maybe relocating the fulcrom point of the Sear pivot???
Everything about this gun is right. I think even way back then, the fears of a light trigger on an entry level rifle scared the Gamo Legal's...
ZVP
-
If I rember those old gamo's right, the sear actis diretly on the piston's sear...no middle links. Think in terms of limiting engagment by limiting the amount of "bite".
trigger is a thick foremed sheet steel part (again, memeory is hazy after so much time) and hardened....it is soft under the hrdening, so if you file/stone too much and break through to the soft settel under the surface hardening, end up with a fast wearing sear that won't last a tin of pellets.
-
OK heres a helpfull tip. If you file on the sear and break through the hardening there is a way to recase harder the steel brownells sells this stuff which when applied to metal puts a hard surphace on it again. Lots of home tuners use it to reharder parts after tinkering. I think its calles kaseit or something like that. This stuff will allow you to do the needed work on your sear and reharden it so the adjustments will last. Hopw this helps I want to see how well you do since i have one of these rifles as well. gook Luck
-
.
Have you ever used this stuff?
It requires red heat for a while, which means if it's a small piece, it all has to be heated red.
I've used it a few times, and if the part is heated too long or cooled unevenly, as might jhappen with a torch, things can distort.
I had to lap out a small bushing and a flat pivot plate that distorted when they cooled.
Probably the tolerances are loose so it won't matter, , but just thought I'd mention it.
-
Well The trigger idea is still on the burner so to speak...
Ya know there is even another way to attack the topic!
I could maybe extend the trigger, via a trigger shoe (ala, a Chinese KL-3B Fast Deer fix), and get more leverage on the mechanisim?
I did this with my .177 F/D and it worked wonders! Same trouble with the KL-3B but it is actually a "direct hook-up sear".
The Gamo/Daisy120 uses an additional leverin it's trigger.
I KNOW someone in Spain MUST have a fix for this, as the Cadet was a long running model over there!
The rifle is simply too GOOD to not have someone have done trigger work on them!
Hmmmm, anyone know any English speaking Spaniards we could contact????
Anyway. I am still thinking on fixing this rifles ONLY problem!

KaseKnit (or some such spelling...too lazy to out to the shed to check).
For small parts, it's better to solidly iron wire them to a larger chunk of steel and heat treat them both...more mass makes the process a bit easier.
Have used it may times, and it will do the job. Usually better to do several treatments on thickish parts, fewer on thin parts.
-
What is the actual Model of this air rifle ZVP? I am gonna start looking for one. You got my interest up... :)
Gene
-
Its a Daisy model 120 which is a Gamo "cadet" rebadged for daisy. The Daisy models 130 and 131 are good little springers too also Gamo models if I remember correctly. See photo on my previous post this little rifle is all metal and wood little to know plastic the ONLY fault I can find with this little gem is itz horendous trigger. Once theres a fix for that its gonna be golden!
-
Gene, As Jim said the Old Daisy/Gamo 120 is actually a Gamo Cadet.
They're a well made gun, desighed as an entry-level rifle. Velocitys are usually in the low 600's, cockilg is easy, and the sights are clear and solid.
The LOP may be somewhat short in comparison to todays guns, but nothing uncomfortable. (The LOP at my trigger is 131/4")
The components are as reliable as a Claw Hammer, in fact the Barrels appear to me to be at least the equal of any fine European Manufacturers "good Stuff"!
The only problem is that Bi -Brother-proof trigger!
They do come in .22 domestically in Spain and under the Cadet stamp, but the #2 Bore takes a lot away from the little mainspring... You're much better to get a .177cal.
Yep, they are usually cheap when ya find one too!
Now here's a little tyidbit you may want to remember.
Gamo made some "repeater" Cadets that were labled for Daisy as the Model 130"A". They also sold a single shot 130 built on a Cadet action.
Both were re-sprung to around 800fps!!!
Gamo then followed up with a Model 130"B". This was a new model (looks like the Daisy 131, but with a smooth,un-grooved forearm. The BBL is of the plastic shrouded type (also very accurate) and this "B" model can take one of Charlies trigers since the trigger group is of the later model desigh.
My 130"B" is a real barn-burner! Open-Sighted and fired over a bench, it's quite accurate out to 50-60 yds, in stock just broken-in trim.
I really like both of my Gamo/Daisys and also my other two .22 cal British Milbro/Daisys.The Model 120 and 250.
Yea iIkinda like some of the Daisy airguns, and own several models!
HTH,
ZVP
-
Great feedback ZVP. I am going to keep my eye open for one of the 130 B's.... :) The Cadet seem's like a great little rifle. Would love to get my hands on any of the above mentioned.
Thanks for sharing your knowledge ZVP..
Gene

Is the Daisy model 131 the same as the Gamo 130?
Gene
-
Gene,
If I mistakedlly called it a Gamo 131 or 130 up there, please forgive me OK?
The Daisy 131 is in fact 100% all Gamo!
The velocity on the 131 series is where Daisy had origonally intended the models of the 120 and 130 series to be. I don't know why, but Gamo put some pretty healthy Mainsprings in the 130 series. Often they will exceed 800fps with "light" pellets!
The darnedest part about it all is that the different Daisy 130's look like either the Model 120 or the Model 131.The early single shot and repeaters have the 120 profile (W/Steel BBL) and the "B" has the 131 profile (W/Synthetic BBL).
Confusing? Yes, but the preformance is worth paying attention to getting the right model.
HTH,
ZVP :)
-
The reason I asked is I found the 131 and the picture there is the one. Is it advisable to purchase this one?....:) So is the Daisy 131 tigger able to be replaced by CDT's trigger? Is the insides to the 131 daisy the same as the 130B?
Gene
-
Gene,
Sorry for the delay answering ( I just got my HAM ticket and had a call to respond to...)
About that 131: You'll likely have a 600+/-fps rifle that's easy to cock and will surely suprise you with it's accuracy (with the right Pell). Mine all love the Gamo Match pellet.
The rifle will accept one of the " Charlie trick Triggers" and get you an additional accuracy edge too.
The little rifles are tough as nails and most give little to no troubles, EVER!
Please note though that this rifle probablly would be a poor chioce for hunting, as it's power is truely borderline. If you're after a pleasant all day informal Target shooter and plinker, then it's a good gun.
I don't know how many rifles you have, but most shooters consider such a Target/Plinker as a secondary gun, having already set up with a hunting velocity rifle first...
I gotta hand it to Gamo, these inexpensive and durable models are a real pleasuer to shoot and whenever I take mine out, the pellet tin emptys pretty fast. Seems I just keep reloading!
Check the sale price against other comparitive Gamo models and IF it seems to have remained reasonable, I cannot see any reason not to buy it. The picture you have presents a pretty nice rifle.
The good thing about 131's is that many owners do sell very good specimins due to wanting to upgrade and ya usually get good deals.
Good luck making your decision and if you purchas it, you'll see what I mean about "reloading" it a lot and burning up the pellets!

A nice little target rifle that is lite and easy to handle would be nice. Now is it all metal. The barrel looks to be rough. Did they blue the barrels back then? Anxious to buy one..:)
Sent you a private message..
Gene

Gene
NO.
The BBL is a synthetic shrouded steel tube.
I'll try to send pix so you can see one.
ZVP
-
Which Models from top to bottom are these? They sure look pretty. I notice the lengths are different also.
Thanks
Gene
-
OK ya saw the Synthetic Shrouded BBL and the Steel inner "True" Barrel?
Top to bottom the rifles are:
Gamo 500 Sporter
Daisy 130 "B"
Daisy 120.
All .177 Cal.
Dinnertime!
Gotta go,
ZVP
