I put it on a 2260 tube today and it fits perfectly.... It is all metal except for a few small spacers.... even the case is metal.... The cost was about $62 Canadian.... Here are the photos: I also tried the assembly in a stock, and it fits no problem.... Of course there is no trigger guard.... but there is room for one in the recess in the stock.... The trigger is fully adjustable, and comes with an auxilliary hairpin spring to keep people from reducing the trigger pull to zero (known as the "Lawyer Spring").... I removed that spring and put in a small spacer and now can adjust the trigger pull from about 1.6 lbs (1st stage ~ 1 lb.) down to mere ounces (maybe zero).... The trigger neutral position, length of 1st stage travel, length of 2nd stage, and total pull weight are all adjustable and when you shorten up the second stage it is VERY crisp.... I just used a piece of poly tubing for the spacer where I removed the spring.... but if you want to go fancy, you could buy a # 1763-048 like the one I temporarily removed from the sear as a sample to take the photo.... It is 1/4" OD, 1/8" ID and 0.123" thick.... The trigger is a "drop sear" design.... which should mean that the trigger pull is pretty independant of the hammer spring weight.... About the only thing I don't like compared to my modified Disco trigger is that the 2nd stage pull is a bit light compared to the 1st stage.... ie it is only a percentage (about 60%) increase in pull.... I can set the Disco trigger up for 1/2 lb. on the 1st stage and still have about 2 lbs. on the 2nd stage.... I like that in a hunting trigger.... On the other hand, this trigger can be set up VERY light and still be safe.... I'm sure this ratio of 1st to 2nd stage pull is much more typical for a two-stage trigger, however.... Crosman really did their homework on this trigger.... If somebody comes up with a trigger guard to fit it.... it would be a perfect mod for a Disco or 2260.... It would also be a good assembly for a custom gun instead of having to make your own from scratch....

I can't quite see because the secondary sear ("strut") is in the way - does the safety work by latching that little black pin? 2. Are the captions for stage 1 and stage 2 possibly reversed? 3. Using crude measurements (laying a ruler on the computer screen) I get a 57% difference in leverage between the two stages, so your 60% makes a lot of sense. (In fact, I'll bet you got your number in the same way, but with more precise measurement.) 4. I can't really see a good way of widening the difference between the two stages, save for adding an adjustable spring that comes on just when you enter the second stage. I did that on my Mendoza - it's not a true two stage trigger, just a marker that signals the moment of release: 5. Finally (and this is just a flight of fancy): The separation of the trigger blade and safety and the position of their respective pivots makes me wonder how you could re-work it into a double set trigger.... _________________ ¡Listo! ¡Apunte! ¡Fuego!   Posted: Mon Jan 10, 2011 8:28 am broommaster2000 Moderator Joined: 10 Mar 2007 Posts: 5714 Location: City of Groningen, Groningen, The Netherlands Hmmm, I might want to try that on my Disco. Does this also mean the 22xx grip fits on the M-rod? _________________ BIG GAP   Posted: Mon Jan 10, 2011 10:13 am rsterne Moderator Joined: 15 Jan 2008 Posts: 2998 Location: Coalmont, BC Correct, the safety latches the roll-pin on the intermediate lever.... The adjustments are labelled correctly.... The left hand screw is what contacts the lever at the end of the 1st stage travel and moves the trigger during the second stage.... that is correct.... However, the gap between that screw and the lever sets the 1st stage travel.... The right hand screw is in contact with the lever during the first stage movement and lifts it during that stage.... however, it dictates how much engagment is left at the end of the first stage.... and hence the 2nd stage travel.... I labelled the screws as to what TRAVEL they adjusted.... but you are correct, the contact points on the lever are actually opposite to the labels.... Confusing, Eh?.... My measurements gave 62% (and yes, I used that to refine my 50% guess).... Haven't given another spring any thought.... where would you put it?.... I don't know what a double-set trigger is....

I recall that one of my friends tried it on his and it didn't fit. _________________ BIG GAP   Posted: Mon Jan 10, 2011 11:31 am Slavia Moderator Joined: 31 Mar 2008 Posts: 4382 Location: Waseca, Minnesota, USA Quote: Haven't given another spring any thought.... where would you put it?.... Maybe replace the "lawyer" spring with a lighter one for the first stage - like a butchered safety pin, for example. Then rig some sort of plunger button (like you see on bow rests) to replace the current adjuster screw. Instead of adjusting spring tension it would adjust button position so it contacts the intermediate sear at the exact position where the geometry (leverage) changes. Quote: I don't know what a double-set trigger is A traditional trigger works by applying pressure to the sear. A set trigger works by releasing a small spring-loaded piece (fly) that moves through space and dislodges the sear with its momentum. They are common on current and older side-lock muzzle loaders, and I have seen pictures of older sporting Mausers that had them. You cock or "set" one of the two trigger blades, and have other release it. The engagement between the two can be adjusted for a "hair trigger," since there is full engagement between hammer and sear, and you don't set the trigger until you are on target. A variation is the single set trigger, as seen on older Newtons and current CZ's. There you set the single blade by pushing it forward, and discharge by pulling as normal. Here is a Thompson Center double set trigger: It can be operated normally by simply pulling the front (main) trigger so that it presses the sear: Or you can set the rear trigger: And then press the main trigger until the rear springs up and whacks the sear: All of this is purely academic, since you have a great trigger as is. Still, you seem like the kind of guy that both likes things a notch above ordinary, and has the skills to pull it off. Just planting some ideas for those long winter nights. _________________ ¡Listo! ¡Apunte! ¡Fuego!   Posted: Mon Jan 10, 2011 8:11 pm rsterne Moderator Joined: 15 Jan 2008 Posts: 2998 Location: Coalmont, BC I have better things to do on those long winter nights....

Some might fnd it odd looking, I like it. Rod _________________ Close doesn't cut it! In Fishing or Shooting!
