Help with Derringer

I didn't know where on this forum to post this question so I'll start here.
I have a cobra derringer in 38 special.
Could someone please tell me the steps to disassemble it.
I would like to polish the hammer and trigger to improve on the 40lb trigger pull.

To improve the trigger pull. Also want the safety easier to operate. I'm sending it back to the factory to be worked on. They have a full lifetime guarantee. Anything goes wrong with it, they fix and service it free.

I can understand the issue with the cross-bolt safety, but they may not address your complaints with the trigger action. There's a pretty good reason for it being heavy, and...for the intended purpose of the stack-barrel derringers...having a light trigger isn't at all necessary.

It's not a target pistol or a range toy. It has a singular purpose, and it's strictly business. It really shouldn't even be fired all that much, aside from a few rounds now and then for periodic familiarization.

The little 2-shoot pistol is a last-ditch emergency tool, most often deployed at powder burning distances during a hand-to-hand grapple with an attacker. As such, that heavy trigger is a guard against shooting too early and wasting half your ammo...or shooting yourself as you try to bring it into the fight. It also adds an extra measure of safety should it be dropped during the struggle. Derringers have a nasty habit of inverting when dropped, and landing with the business end pointing up.

As such as the gun is, accuracy isn't a concern, and target accuracy is the reason that most shooters go to the trouble of having trigger work done in the first place.

Best advice: Have the safety smoothed up a bit and leave the trigger alone. The jewels that you save could be your own.

I did a bit of searching on these and the other makers clones. it seems a consensus was DON'T! These are basic, last ditch twoshooters like JT said. Factory is about all I would recommend.

I got my hands on one of those Derringers yesterday...and the trigger is truly horrible. It breaks at about 18 pounds, but the leverage and the narrow width makes it seem to be much more.

It's far heavier than it needs to be for safety, but still manageable in a hand-to-hand struggle, which is the pistol's niche. I was also able to make it a bit better by dribbling a few drops of light machine oil into the hammer/sear area, and lightly boosting the hammer a dozen times. Lightly means lightly. Boost it jut a bit too much, and you can pull on the trigger 'til pigs fly, and it'll never trip. As it progressed, it did allow a little heavier boosting...but I still had to let up on it gradually while maintaining pull on the trigger. It seemed to cut the force required by about 15-20%.

It's also a fairly large piece, and about as heavy as a 2-inch Model 36 Smith & Wesson revolver in the same caliber that has a 5-round capacity as opposed to the Cobra's two.

Given that, I really can't see any practical reason for buying one, other than the cool factor. The little J-Frame Smith is an infinitely better choice for a carry gun.

I couldn't of said it better. Been my choice for BUG/off duty for 35 years. And you get 5vs2,more reliable, safer and you can work on'em.
