Investarms Plains Pistol Half-**** Not Secure

[BoomStick]

Current parts diagram for the plains pistol shows no fly. I checked a couple of their set trigger models and all show a fly in the lock (as required for set trigger).

A photo or 2 of the OP's lock would be helpful. And was the gun bought new or from a prior owner.

Hmmm, dunno. Never owned one but i put 2 kits together for my uncle as a present in 2019, they both had one.

Here's a couple pics of the lock at half ****. I wanted to do a video of what I was talking about but cant figure out this camera. When you pull the hammer back, there's 3 clicks of the hammer to full ****. the first click is half ****, the hammer holds in place. when you pull the hammer past half **** you hear a second click. this is what I was told that it's made so you can ease the hammer down on the nipple without going to full **** and pulling the trigger. If you let go thinking its full ****, the hammer drops on the nipple as if you pulled the trigger, when you pull the hammer all the way back you hear a third click and that's full ****. I know it's not the safest and there's nothing in the book that mentions this feature. I'm not disputing anyone's opinion that this shouldn't happen. I'm just telling what I was told about why this pistol does it. My pistol is new not used. I purchased it from Muzzleloaders. com

This one has a fly and that second click is the sear going past the fly. Normal operating and correct operation.

Thanks Phil. I was hoping I didn't have to send the gun back

I have two of these pistols, just checked. One does like the OP, but only 2 clicks. First click is half ****, then pull it back to kind of a hump then lower hammer, to rest, or pull back for full ****.
The other only has two positions, half **** or full ****.

Hmmm. I have the Lyman Plains Pistol which is identical to the Investarms. It only has two clicks. If I thumb the hammer back from half **** to full **** and really try and come up just short of full **** it will sometimes then release all the way down to the nipple. But I really have to work at it. I either think there is a defect in the OP and other locks or it's operator error. Here are 2 pics. First is half ****. Next is full ****. As you can see there is no fly. Pretty simple action. My pistol is 9 years old.

This lock has a fly as well, easy to see in the second photo.

I'm no expert but if you say so. I was not aware that the fly engaged the sear. On my double trigger rifle locks the fly just seems to swing free and not engage anything.

 

[Phil Coffins]

That fly should move freely when the sear is in the full **** notch, if not it is being held up by something. Clean, oil and / or deburr, it won’t take much.

 

[smokeum54]

Yep, what Phil said

Most definitely a fly, if you do not like the "de-cocking" aspect of the lock and you do not have set triggers take the lock apart and remove the fly, now you have two clicks, half and full **** and that is it.

I would not but that is just me.

 

[TCMonts]

If there is a fly you can remove it and it will work like you want.

Thank you for the reply. Your pics show exactly what my own

I might try that because I’ll already be taking it apart for refinishing.

The woodwork and the metal were so rough in gun as purchased that I had to redo everything. The woodwork in particular is so beautiful now that I sanded to 320grit, applied shellac and applying multiple coats of “Tried and True” varnish oil - it’s amazing
