Polycarbonate Shotgun-Style Priming Grip for Longshot

 
I know there have been many other shotgun-style grips but I’m sharing mine just to have more on file for users to choose from. The purpose of this grip is to be used with a Longshot which has had the front portion cut down to decrease size. The fit of the grip is tight in order to eliminate wasted space or bulk.

I have two versions of a very similar grip. One uses only polycarbonate as the main material, while the other uses aluminum bars as the "pushing arms.” The main difference is the look and feel. The polycarbonate version hugs the Longshot shell a bit more which is nice, but it could potentially cause harm to your paint job because of the lack of clearance. The metal version is lifted off the shell a bit more, protecting the paint but also making the grip wider than it needs to be. The metal is also nice if you're running a very big spring and are worried about the polycarbonate bending. However, 1/4" polycarbonate is sufficient for most spring combinations you can comfortably add to a Longshot.

Instructions:
1) Download and print provided template onto adhesive backed label paper
2) Cut out template and adhere to 1/4” polycarbonate
3) Drill and cut polycarbonate to match template
4) Drill and tap mid pieces along purple “tapping” line
5) Sand edges of polycarbonate for comfort
6) Adhere connector piece to the grip and the extension arm
7) Assemble remaining pieces using 6-32 machine screws
8) Cut slot in Longshot to match priming grip – Note: you must cut off the front bit as if you were integrating a Longshot Front Gun (LSFG) for this priming grip to fit your Longshot properly.
9) Cut two #8 threaded rods to fit into the front and rear guide of the grip
10) Line up grip and insert #8 threaded rods into appropriate holes. Secure with nuts.

I forgot to take pictures of the grip before assembly and the Longshot is now in the possession of Xellah. Here is a single picture of the installed grip.

This isn’t really a great tutorial, but it’s documentation of another working priming grip for those users that want to build one but don’t want to design it themselves.

Nice job I will be doing this on my next longshot.

Great job Coop! I like both of the designs a lot. I am definitely going to do one of them.

After seeing this on youtube i was truly hoping you would post this!! Excellent job

Interesting design, thanks for sharing.

How is it comfort wise with it being rectangular (personally I cannot stand wider rectangular grips)? I imagine you could add your own grip onto the bottom portion if you felt so inclined however.

Nice work.

This was concern of mine in the designing stages, too. This design allows for a huge amount of sanding to the bottom of the side plates to allow for a more comfortable grip. The bottom support piece isn't flush with the bottom, so sanding the edges off won't affect the assembly. Also, the front plate allows you to cup most of the grip on the side, but also add a finger or two to the front to get a more solid pull.

I've made a PVC based grip and can't really say it was more comfortable than this. Adding foam or padding of some kind could probably make it more comfortable, but I had no problems with it and I put about 200 rounds through it in one "sitting."

I'm pretty big an aesthetics, and i just think the pvc grips look cheesy no matter what you do to them. This looks awesome to me though
