P4 Metal Outer Barrel Set

P4 Metal Outer Barrel set

The outer barrel is very nice and fits well, the inner barrel is a little tricky to get in, basically twist and force it in. I took the screws out first, not having instructions, but made it worse. The other two parts are also metal on the original, I kept the old front spring retainer in as it is heavier than the new one and leaves the pistol better weighted.
