So after welding up the holes on the 340 M&P and adding the titanium cylinder to it, I found a no lock 340pd today locally and it followed me home.
Two is one and one is none...After pocket carrying a 11.3oz j frame, everything else feels like a brick. I had to have a backup for the system to feel bulletproof. So I guess I can carry my 340mp without a care for scratches or problems..now I got my backup system.LOL see what I mean about scandium sickness?
