I want to purchase a M327. I have pretty much made up my mind based on the price point this is the next firearm in my life. I called Taurus today for a quick qa to see what the warranty return rate is for this weapon and what they might recommend. They stated that earlier the firearm had some issues with extracting certain casings but recently they have been spot on with low warranty claims. This I wanted hear I asked about ammo and surprisingly they stated they do not recommend 327 Federal magnum since they have not tested this ammo in the firearm. I stated "are you sure about this" and the rep said that was the protocol they were told to repeat. This concerns me becuase it is "the" major selling point for me and I assumed why the firearm was called the M327. It would not be my primary practice ammo but certainly my defense load and I would shoot it once in a while. If anyone could clarify this please do. My finger is on the purchase button at Buds but now I digress (possibly)!
