Convert an FEG p9m-9hp to 357 Sig

[9mmhpfan]

I have a 9mm FEG p9m-9HP and I know that there are kits made by FEG to convert the P9M-9HP to 40 cal and am planning on getting one soon but I was wondering if you could convert to 357Sig as well? Would it be expensive to do so or would it be a cost effective project?

Just curious

Thanks for any information

I want to know too. I know Barsto makes runs of .357 Sig barrels for HP's (says will work with clones) once a year.

I've seen kits that convert .40 guns to 9mm, but not vice versa -- generally because .40 barrel diameter is generally quite a bit larger than 9mm barrels. (And .357 sig CHAMBERS still have to be as large as a .40 chamber.)

I've been told that the Browning Hi-Powers that shoot .40 are NOT the same as the ones that shoot 9mm -- they are subtly beefier. Bar-Sto won't even discuss building a barrel for a 9mm gun to shoot a .40 or .357SIG round, unless the underlying gun was built to handle that round. If you've seen Bar-Sto making/offering .357 SIG barrels, you can bet they are for the .40 BHP, not the 9mm.

If the gun can be modified to shoot the .40 round, it can be modified to shoot the .357 SIG round.... but, is the resulting barrel stout enough to stand up to the strain, over time?

Do not do it!

The P9M will broke into parts.

I've seen normal 9 mm P9M with broken de-locking wedge (in the frame above the trigger) broken after some 1000s of rounds from an IPSC shooter.

Can not withstand .40 or .357 SIG on long run!

I agree with both replies thus far.....the 40's are built heavier in the frame/slide and the 40 barrel isnt a drop in by anymeans.
If you want to shoot a 357 Sig, Id get an FN/Browning 40 HP to start with and go from there........its a simple barrel change from that point.
It will cost you less than buying a conversion for your existing gun, an extra barrel and replacing the gun after the fact...........
Shoot well.
