Taraus is not as bad as the internet haters say. But it is also true they have higher % of returns than "name brand" guns.
Other than QC in general , their problem is being too inovative. They will introduce new designs and new materials very quickly before adaquate testing and working the bugs out. And then half of them get discontinued by that time, so lots of orphans floating out there.
Specifically : The M92/100 family they've been making forever , and have figured out. The steel M85's they've been making forever, and have figured out. Several gunsmiths I trust have given thumbs up to PT1911's ( one of them a notorous Taraus hater of everything else they make).
If I could have found a M431 in person , I would have bought it.
The M445, M450, and M455 are great concepts , and don't have any comparitive counterparts from other mfgs. Likewise a .41Tracker is an intreguing unique concept. The friend of friend who had one had no problems, but let it go because he primarily loaded cast bullets with longer noses, and the Taraus cylnder is strictly for SAAMI spec COL.
So if you have a steel frame Taraus revolver in your hands , and know how to inspect a revolver, don't rule it out. But I probably wouldn't buy one over the net sight unseen.
But the part no body has asked yet , are you really sure about a 9mm DA revolver ? I own a M940 , and have to say that at best DA 9mm revolvers are a very niche item. Yes , they have a better expansion ratio than .38/.357 snubs. Yes if your employer restricts you to issued ammo only , and that happens to be Cmm , a small revolver does have advantages as a BUG.
If the chambers are reasonably close to spec , they are very ammo sensitive. I don't mean just accuraccy , but even chambering , or going bang. I'm guessing the current Tauri have generous diameter chambers and throat , because none of the reviews mention chambering issues. But the quoted group sizes at 7yd sound like group sizes fired at 20 or 25yds.
So unless you have a specific reason more compelling than simply owning a 9mm semi , I'd recomend a .38 instead.
