My nf, with permanet 3.5 inch cpvc barrel.

My nf with the holster

Couplered nf, with 4 inch cpvc barrel

After the reduction mod, there was a big hole, and I put some scoth brand putty to cover it, and around the coupler to ensure that it is sturdy.

I have another nf, and more materials, so I am hoping for any constructive critism, or comments, so I can decide what I do on my next nf.
