Stock 1377 Trigger Fix

[IntegratorDx]

Hi:  I began to notice like millions of others that the Crosman 1377 5.8 LB + - trigger pull is horrible.  I researched and watched some YouTube and tried the simple spring replacement.


So at first I removed my factory spring, and with a few different various weaker springs from Ace I started to experiment.  The weakest spring I found which I thought would be perfect was too weak in the buckled position that it tends to go into, just as the factory spring buckles to the side a bit.  So I tried a medium strength skinnier spring which still fit on the tang and it worked.  With my homemade water and coat hanger trigger gauge, it measured 4 lb 13oz.   better but still bad.

Then after reading the Link Below, it worked much better after polishing the sear and trigger and adding some grease.
About 2LB 15 oz.

I still wasn’t happy, and didn’t like the buckling of the spring.  I knew about the 22 casing guide trick but didn’t try it yet.

Then I read this link from this site:

several paragraphs Down TooJung2Die had a nearly solid pillar inside his spring with a nail on top….

So I used the weakest spring that was too weak in the buckled condition with a piece of brass tube and a nail head,,,, and now my trigger pull is around 2LB 4 oz average…

Way Better and my accuracy has increased Tons.   Old news for many of you but maybe the new Crosman 1377 owner can tweak his trigger using these methods

This one is from the CAPOF by the late Quickster.

Yeah, that “Taming the Shrew” article is the exact same one from this site, that you referred Spooner… someone copy and pasted from here to there or from somewhere else…. I polished in those exact same spots… maybe over time some natural wear will improve things also…

I did all the polishing suggested in that article and it improved the trigger considerably.

I didn't have any Legos on hand, so I went with this...

The trigger itself still had a little friction, so I changed it to one of these...

These were not as expensive when I bought mine a few years ago, but they gave me very smooth triggers. David at Alchemy does fantastic work with these upgrades.

Thanks Spooner for that information…
Wow lots has been done in redesigning this trigger…. the roller is very cool.

Question for you…. When I took of my trigger cover and wiggles it off of the pins… Later, I noticed the squish washer laying there on top of the left half of opened up gun, but after I had pulled the trigger out from the right side of handle. 

Does that washer go back on the Left side of the trigger as you are facing the target or on the right side of the trigger?

The schematics show something different than what I believe mine had it.

It's been ages since I had a stock trigger apart. If I remember correctly, it goes on the left side. If you are not sure, try it on each side and look at where the back of the trigger engages the sear. The side that puts the trigger best aligned with the sear is where it goes.

There are washers (copper or brass, I think, and stainless, and zinc plated) at Ace that you can use to replace that single OEM washer; I use 2 and lap them to fit as they are normally too thick.

Magnum Air Power’s trigger spring has just the right tension, but it’s not practical to buy just it and be charged for shipping. Like Spooner, I use Don Cothran’s stainless roller trigger—- I own 3 and 2 Blue Forks. In my Blue Fork triggers, I use Magnum Air Power stainless Super Sears.

Hmm, I used to have springs made for me when I was still in Asia and found that I could use the softest and shorter ones by tensioning it with a washer or 2 held by the pillar. If 2, I would glue them together and if too wide, I would just sand it.
