Selling a complete drop in 9mm conversion kit that converts .40 S&W down to 9mm. 100% Beretta factory, this includes complete 9mm slide assembly (ejector, FPB, firing pin, springs, safety/decocker, iron sights) and a 9mm factory PX4 barrel. Also includes two nearly new 9mm 10-round factory mags. Under 500 flawless rounds on slide/barrel. Great condition with only some holster wear on slide and normal lock-up rub on barrel. Frogs Lube from day one (proper heat cycling). San Francisco Bay Area. $400 plus insured shipping.
This really is an AWESOME setup that thankfully the PX4 platform was built to do easily. All you do is pull your slide off, remove the recoil assembly and put it on this complete assembly then drop on your frame. If you can even find the part in stock, all these are easily the price of a new gun however it gives the flexibility of dual caliber without needing to drag two guns to the range. Of course at the range you can practice with 9mm then put the other .40 S&W slide back on for home defense. Seriously, it takes about 10 seconds to swap and is no different than removing the slide for cleaning. I can even show you if you buy it from me locally.
For those curious about doing this without a new slide, know you cannot just put a 9mm barrel in your current .40 slide. The barrels have different O.D. sizes and it won't lock up with slide correctly. The 9mm slide is not only choked down around that smaller size, but the inside/underside of the 9mm slide is significantly machined out lighter to compensate for the lesser caliber recoil.
