Gerard I did all of that..I polished, washered the trigger assy and replaced the spring w/ a lighter one..Like you I do not like 2nd stage..Here is a very simple but effective mod that I did on all my Crosmans..

My son's gun w/c I ordered from the US and sent to the Philippines but he does not like shooting at all so I made myself the new owner lol! The gun has gone through a lot of changes over the years though

..

Notice the rubber on the trigger's tongue..I got them from disposable lighters and after so many years of using my Crosmans I have yet to replace one..You have to glue them and sand them carefully until you can cock the gun..It acts as a trigger tensioner if you get my point. You can simulate it by putting a thin cloth on that particular area then cock the gun..The slack on your trigger will totally disapppear.

Thanks Crossliner. But since I posted this thread I realised that the tripping of the sear now happens within about 2mm. My modifications have dramatically shortened the single stage before firing. The too-long travel which bothered me still was over-travel, after the shot. So today I've simply added some steel filled epoxy putty to the back of the trigger, filling in up to the trigger shoe, then filed that and polished it until there is only about 2mm of travel after the shot. Short enough not to bother me. Adding an adjustable screw to the trigger or to the frame would have accomplished the same thing.

Hi Gerard, I'm sure you've checked, but just to keep up general awareness for others that read through this thread...
Any mass added to the trigger blade increases the chances that a bump will move the trigger. Couple that with a light single stage with short travel and the chances of an accidental discharge increase. A set screw in the frame for adjusting over-travel has the advantage of not adding to the mass of the trigger blade. There are always trade-offs between trigger safety and ease of use, so it's important to test under safe conditions and make sure you're comfortable with the safety margin for the intended use of the gun.

Speaking of Mods for the 2240
I'm thinking of ordering a Velocity Adjuster from Scopes and Ammo.com
But, I've read somewhere, that rather than improve performance it really
only increases Gas usage? True?
Any suggestion on websites for mods?

Not too preachy. Safety is a serious business and needs mentioning. Hadn't thought of it actually, much less checked... so I'll check now.......... Okay, I've banged on the grip and on the padded stock and the main tube as hard as I could from every available direction, actually hurting my hand a bit. No accidental discharge. And I really doubt it'd be possible even if I were to drop the gun. Though I did the standard slight shave and polish to reduce the depth of sear engagement with the hammer (otherwise it tends to drag on the hammer causing inconsistent velocities, depending upon how tightly one tightens the rear grip frame bolt) there isn't the slightest sense of it being unsafe. Thinking about it I can't imagine which part of it could fail to remain steady under some sort of impact. I suppose if I were to smash the gun with a heavy hammer from the bottom that could cause the sear to jump out from in front of the hammer owing to its slightly unbalanced mass before and aft the pivot... but I doubt it. Probably damage the scope long before that happened, judging from the impacts I just smacked it with. I think if someone's set things up badly in a mechanical sense then accidental discharges might be possible, or even easy, but that's just bad workmanship.

One of the popular trigger schemes. Two-sear with upper “falling” sear.
