I use Singer sewing machine oil. I was given a miniature replica 1911 that you can cycle by hand

but it wasn't feeding reliably. So I got Singer oil due to their connection with the highest quality 1911's.

It worked flawlessly after applying the oil. But any oil on steel polished to 1000# will be good.

Aquaplaning or dynamic fluid bearings need more velocity and time to establish separation.

But there will be some of this effect at a microscopic level when stationary.

Using a wide sear lowers the stresses on the edges. Mine is 8mm wide with machined square faces

whereas a Crosman 22xx sear is something like 3mm, with a rough punched edge, engaging

with a round edge of the striker - making the contact very small and the contact pressure high.

I don't see it wearing enough to change the function in my lifetime.

That leads me to remember another advantage of a drop sear: you can have lots of sear engagement

with the striker without making the trigger pull heavier, longer, or more creepy.

You can have say 2mm of engagement with a drop sear making it very safe.

Whereas with a standard Crosman 22xx, people reduce the engagement to nearly nothing

to get a light and short trigger pull. Like 0.1mm of engagement might feel nice

but it's on the verge of firing from being bumped. And if parts wear it gets closer to letting go.

I actually have used a similar trigger-sear system for a spring piston airgun

but it was a Nerf sniper rifle. It had a fairly strong mainspring but not on par with real airguns.

The trigger was light for what it was holding back.

Which part? As a whole its advantage is doing the job efficiently and effectively.

I have not seen this combination used before but each of the elements have been around.

e.g. the drop sear or falling sear is more common in rifles or higher end pistols

or in extreme modification of Crosman 22xx grip frames.

In pistols like the 22xx the geometry does not readily suit a drop sear so usually

an intermediate lever needs to be added. This introduces more complication room for play.

Although a well-positioned intermediate lever can get the triggering force to nearly nothing.

Not using a drop sear, like the standard Crosman 22xx, usually gives a more creepy trigger break

as you are un-wedging it from the striker against the full force of the spring.

Here you go.

I have not yet added up the costs for this but the stone grips added a significant amount.

Yes that is how it works.

The two lower legs of the trigger can be drilled and tapped

with a travel stop screw on the forward leg and a ball plunger screw (2-stage feel) on the rear leg,

allowing it to be highly adjustable with a short break.

But with the addition of the safety lever I have left this out to make the safety safer.

The trigger is nice enough as it is.

Yes bead blasted. Requires preparation to keep the beads out and thoroughly cleaning

any that make it inside.

Any chance of a photo look down the sights, i like a thin front sight on a pistol.

BIG QUESTION... How Much ? 😎
