Title: Anyone install their metal trigger?
Post by: Swschu on June 07, 2019, 10:29:46 AM
I would like to know the level of difficulty installing the metal trigger. I already had two gunsmiths decline the opportunity to install mine. I am getting ready to try doing it myself....but my R51 is my best shooting pistol and I dont want to screw it up. Any advice? Thanks!

I got the trigger and was surprised to find a little spring on top of the original one. The whole project I'm sitting on and will attack it later; the re-assembly from field stripping is tricky, must master that. I got one of those Bench Plate things for punching out pins, and you need to get the proper Roller Pin Punch to protect the hollow pin. Can order one as most hdwe. stores don't stock, and many don't even know what a Roller Pin Punch is. Just has a little swell or tit on the end, that fits in the hollow pin and keeps it from being crushed when punched. Gunsmiths don't want the liability of doing trigger work if they can avoid it. Good luck, I'm sure you'll get it done. I enjoy shooting the little R51, and hope to get mine back together soon, with or without the after market trigger.

Were you able to get it together, Art?

Have triggers available, hitting the website today or tomorrow!

Not yet! Sometimes if a little project stumps me, I'll lay it aside for days or weeks and come back with fresh eyes...thanks, I'll keep you posted!

I am interested too.  Just ordered mine

You should consider getting one of those 'benchtop' pin-punching blocks they
advertise in the gun publications...also, be sure to use a true "roller pin punch", so as not to damage the roller pin...it's hollow, and you don't want to peen it over.
(This was suggested by DangerCo's. site, too.)

Finally sat down and filmed a how-to on changing out the trigger!

A Thousand Thanks! It seems simple, but we're not all engineers! Just need a little visual help. Good idea!

Hi, the video was great; not to nitpick, but the orientation
of the little spring, was a bit too fast, would have liked to
see closer or longer. Thanks, though, it is helpful and I'm
sure others will benefit, too.

Thanks for the video...looks simple enough to give it a try. 😊

OMG! You are truly in the best tradition of the Engineering Profession! Wow! A thousand thanks! I still am sitting on this little project, will notify when completed.
Engineers rock! (Guess that's how we got to the Moon!)

Installed my metal trigger last night....followed the instructions that came with it. It was simple! Didnt remove all the trigger wobble but it is metal!

I installed the new trigger the other day. I took my time at it and spent about 20-30 minutes on the operation (... okay, it might have been closer to 45 or 50 minutes).  Before going any further, let me say that if you havenít watched Cameronís posted install video, take some time and do so; itís well worth it.

      Some additional observations on my part (apologies if this is trivial to some of you, but as a novice the following stood out to me): 

         The pivot pin must be driven from the left side out the right side of the frame as that pin has about two to three millimeters of knurling on the right side - consequently you will use a little more driving force, at first, until that knurling clears the frame; after which the pin can be pushed out with the lightest of taps. Likewise, when installing the new trigger and driving the pin (now from right to left) into the frame, youíll need to apply a little more driving force at the end of its travel when the knurling engages the frame.  Either direction, start with gentle taps and gradually increase the applied force until the pin moves.  When reinstalling the pivot pin, I found it helpful to use a larger than 3/32 pin punch until I got the pivot pin almost to the frame.

    Before installing the trigger into the frame, I took some time to test fit the pivot pin in the new trigger, inserting it by hand and making certain that the trigger fits firmly and moves freely on the pivot pin.  Cameronís trigger worked fine, but machining tolerances can rear their ugly heads when you least expect it.

     When installing the roll pin into the trigger, definitely follow Cameronís suggestion to line-up the trigger and connector with a pin punch before inserting the roll pin.  FWIW, my factory roll pin was too tight to easily fit in the new trigger; after a few attempts, I gave-up and used the supplied pin - thanks Cameron for supplying the replacement roll pins!  Also, at this stage of the operation, I might suggest a small piece of soft plastic being used to wedge the trigger (against the frame) in the forward position so that the roll pin hole doesnít slip halfway inside the frame while youíre trying to drive that pin (yep that Birchwwod Casey black finish touch-up pen will be used on my gun - just a small nick on the frame about the size of a pin head).


        My impressions of the installed new trigger:

     Very nice!  What remains of the left to right wobble of the new trigger (compared to the factory original trigger) is negligible.  Indeed, comparing it to a friendís 1911 Gold Cup, the Gold Cupís trigger exhibits more play in that dimension than Cameronís R51 trigger - Bravissimo!


     A final FWIW, before installing the new trigger I took some quick measurements of trigger pull with the factory trigger in my gun; they seemed to average-out at about 6.5 lbs.  The new trigger seems to average-out at slightly more than about 6.75 lbs.  I believe this is due to a slight change in the trigger profile which is affecting the applied leverage of the trigger on the sear.  Does it bother me?  ... No, but I readily acknowledge that this touches upon a very subjective issue among shooters.  I do not intend this as a negative strike, but simply to bring it to your attention; if this is important to you, this trigger might affect your felt trigger pull - then again, I also suspect that due to machining tolerances, different guns may exhibit varying results here.  It's a bit of a tough call.


    Last, but not least, ... did I happen to mention how cool it is to have a metal trigger on an otherwise all metal gun?   (Okay, there is still that glorified ink pen eraser which tensions the extraction claw - but weíll overlook that discussion for the time being for the sake of basking in the glory our current victory!)

The install is not rocket science; watch the video and heed the various posts in this thread.  If you're new to this, just take your time and use your common sense.  No one is out to set an installation speed record; patience will be your friend!


PS. Regarding Roll Pin Punches:

While I found that Menard's had roll spring pin punches, the smallest they had at my location was one size too large 1/8" - YMMV.  I noticed a set advertised online by Walmart but found none in the store - although I had looked in the tool section of that store.   When I ordered online from Wally World I noticed they listed the set as a gunsmithing tool; since some Walmart's do sell guns, you might try looking for that roll pin punch set in their gun section - this is just a hunch though, I haven't had opportunity to follow up on this.   Good luck

Good info! BTW, Wal-Mart will not tell you which of their stores have rifles and shotguns...does anyone know of a non-Wally web site that lets people know
which stores sell firearms? I haven't installed my metal trigger yet, but will study and re-read your fine tech tips before doing so...

Mine came today - with a "DangerCo" patch! How did they know I have a skirt full of firearms patches? Now it'll have one more!

Installed. I waited until the disassembly tools arrived, and boy did they make a difference!

No real problems, it felt like the new trigger was a tiny bit wider at the spring - which makes sense. I ended up re-using the stock roll pin as it was tight enough and the new one would have needed squeezing down a bit. This way, I have a spare.

I used a "pistol block" to support the frame while driving out the upper (pivot) pin - a handy tool to have. The sideways wiggle is VASTLY improved - and it does seem, as another poster noted - that there is a slight increase in trigger pull weight, but nothing objectionable, nice and crisp. A bit of oil on the pivot pin helped it go back in easier.

I would have bought a red trigger as illustrated in the video had it been available - or better yet, "Remington Green", but that's nit picking. Pictures:

After installing the metal trigger, have there been any issues with trigger reset?

I ordered my roll pin punch from a big-box hdwe. store; Home Depot.

The video looks excellent. I won't be able to try though until I get my trigger in. Just ordered it.
