Converting a 9mm to .40S&W

[Localizer]

All,

 

What’s required to change calibers in a Tanfo pistol?

 

Obviously, barrel, magazine & recoil spring, but what other components should be changed? What about extractor? 

 

Separately, which pistol slides interchange onto frames? Are the stock frames compatible with limited pro? What about limited & Stock interchangeability?

You would need to utilize a complete .40 slide since the breechface on a 9mm slide is not wide enough to accommodate the larger cartridge. With the .40 slide and the appropriate barrel, you can accomodate 10mm, 38 super, and 9mm since the breechface is wide enough. Then you need the proper recoil spring and and the appropriate magazine. Tuning of the extractor may also be needed for proper feeding.

Super easy, just spend about $750 on a new slide/barrel combo from EAA and slide it on your existing lower. Comes with one 10 round Mag.

 

It may (but not necessarily) be less expensive to find a used one and purchase it.

 

Honestly there aren't any "drop in" barrels for these pistols. But contact Patriot Defense and ask them what they have available, just understand there aren't any "cheap" options for these pistols.
