+P Ammo in Polymer Framed 45 ACP?

[147 Grain]

Just bought a EAA Witness Compact 45 auto (Tanfoglio) with 3.77" barrel and was shocked to find the Instruction Manual recommending against +P ammo in all their polymer framed pistols.

Questions:

* Is this a legal tactic?
* EAA is saying this to prevent possible warranty claims?
* Poly frame actually cannot handle extended +P use?
* Pistol is really up to the task of +P ammo?

Can the dual Recoil Springs be upgraded to slow the slide speed down for better protection of the polymer frame?

Thank-you in advance of your advice!

It's probably best to call the factory for that question. It's possible that the recoil springs were not designed to handle the recoil force of the 45 ACP +P ammo. If that's the case then the action would suffer from battering. I wouldn't consider it a disadvantage to use standard velocity 45 ACP with a good bullet design.

This proves 'tis best to do some research before one makes a purchase I checked thoroughly before purchasing a Sig P220 in 45acp learning they were rated for +P ammo.

Not really sure if there is a need for a +P but if you must have one, all Taurus autos are rated for +P ammo.

Don't do it on any polymer framed gun... even a glock... even alloy framed guns should only see limited use of +p
