Title: How do I install one of these trigger stop things?
Post by: chinaboy on December 30, 2011, 01:12:08 AM
On the Silhouette's and 2300's there is a little screw that stops the trigger after it has been pulled just bellow the trigger.   Can a person install one of these on there own?  Are they beneficial?  Or should I just order the 2300 trigger frame?     I don't have much equipment besides a hand held power drill.  Yet, I don't want to spend on a trigger frame if a special drill bit, screw and craftiness is all I need.

I'm working on building a nice trigger for my 1377.

well ur gonna first need to figure out how big and long of a screw ur gonna want, then yuou need to know the thread size and get ur self a tap and dye kit to cut the threads after drilling the hole..

harbor freight has some decent tap n dye kits.. i got mine for about 20 bucks and its like a 30 or 40 piece kit

It can be done by you just drill and tap a hole i think it's a 8/32 alan screw but not sure it's just a over travel screw it stops the trigger from moving right after the trigger is pulled.

Thanks for the quick replies!  That sounds easy enough with a tap and dye set.  This makes me think that maybe I could add another barrel stabilizing screw my breech as well.  It seems like the same procedure.  Awesome.  And I'm going to take a look at that kit.    Thanks

Yep i added another screw on the breech on my free floating barrel 2240 build.

I added a over travel screw to a 1377 using a <$5 8-32 tap and drill pack from Lowes. The pack contains the proper sized drill bit and a tap to make the threads. Pick up some 8-32 set screws and you are all tooled up.

The angle to set the drill is roughly parallel with the grip frame. Drilling is pretty easy in the soft metal of the frame. Make a little divot in the frame so the drill bit does not wander.

Where did you get that grip frame? I need to get me one if them.

I got the frame and grip from Crosmods, it has a real sweet trigger pull. :-*

X2 on the tap & drill bit pack from Lowe's.  Actually, I used a 6-32 instead of 8-32 and picked up a couple of 6/32X1/4" stainless steel set screws from Home Depot because Lowe's didn't have any that small.  The ones that come from the Crosman Custom shop are 8-32 but I like my 6-32 setscrews better.  See pic.  Man that dust shows up badly with the flash!  I'll have to remember to dust everything off before I take pictures next time.
I used my Dremel and the flex-shaft attachment to drill the hole more closely parallel to the grip portion of the frame.  A regular drill chuck won't let you do as nice of a job.  And DO use a center-punch to prevent the bit from walking.  It will walk badly if you don't!
Cheers,
Jerry

Pretty much the same procedure.  It goes easier with a drill press.  The hard part is deciding how many and where.  I decided on two because it seemed to keep things "balanced" for lack of a better term.  If I remember correctly, I spaced these 1.25" from the original screw but I don't rememeber why I chose 1.25".  I did use 8-32 setscrews for these to match the one already here.
Cheers,
Jerry

Ok, I bought an 8-32NC dye.   The dye says it goes with a #29 drill bit.  The store didn't have a #29 drill bit, but I do have a 1/8 and a 9/64 bit.  I think the 9/64 looks like it would work best.  Do you think I could use the 9/64 without a problem or should I run and get a #29?

The #29 is .136"
9/64 is .140

The 9/64 will work, just don't let it wallow around. If you do not get a tight thread your set screw will not stay in position. Probably good to put a drop of blue Loc Tite on it once it is set where you want it.

Ok, I did it.  It wasn't that hard.  I did use the 1/8 bit and it worked well.  I ended up taking my trigger out for the dye to completely thread the tapped hole.  Once I had the trigger out I thought why not sand it to bring out the silver color.  I then switched all my screws that I got from Mike's Garage.  The 8-32 screw to stop the trigger is temporary until I get a smaller screw.  I tried to attach a picture for the first time so I hope it works. 

Next step it to add some set screws to the breech.  I want to dod some more research so I don't biff it up first.  Thanks for the help dudes!  I think my trigger looks sweet now.   :-*

Nice job Chinaboy.  That trigger looks good.

Get a set screw it will look much better.

Nice job ! that trigger looks nice. I bet you can adjust the trigger stop with out a wrench with the head of the screw not a bad idea, is that what you were looking to do or you just didn't have the screw.

I didn't have the screw needed nor did the store I got the 8-32 dye.  I'm either going to order one from crosman  from the 2300 or search lowes.  The one I have cost a quarter and I bought just to have until I get a set screw.  But, now that I have it it would be nice for adjusting without a wrench.  The screw in the picture could be shorter as it hits my hand when holding it. 

How long are the set screws that every one uses?  Like I said, if I can't buy one from lowes I will order one.

I used a SS 3/8 set screw and it seemed too long for me so I ended up cutting it down to about 1/4. Homedepot had a good amount of screws and such you could try there.

what is the benefit of having a trigger stop?
Title: Re: How do I install one of these trigger stop things?
Post by: JEBert on January 05, 2012, 07:41:06 AM
Millipede,
When the trigger breaks the sear from holding the hammer, you don't want the gun to move before the pellet leaves the barrel.  The farther the trigger moves after it breaks, the more the gun will likely move because you are pulling on it, remember?  The trigger over-travel screw is adjusted to just beyond where the trigger breaks so that the gun doesn't have a chance to move much after the break.  A smooth squeeze is still important.
Another term you might hear in reference to firearm triggers is Lock Time.  Lock Time is the time between  the trigger breaking and the firing pin hitting the primer.  Shorter lock time = greater accuracy potential.  We don't hear much about lock time in reference to air guns.
Cheers,
Jerry
