With any pistol, test reliabilty yourself, as any brand can have greats and duds.
now that disclaimer being said.
I have 2 taurus revolvers. a model 94 (.22 nine shot) and a 605 (ss, .357 jframe size)
i have had no MANUFACTURE issues with either. I have had the 94 for 20 + years. many rounds shot. still love it.
I have had the 605 for a bit over 1 year. it is my main weekday carry (VERY easy to conceal and still have a viable round).
I HAVE had an issue with the 605 (bought used).
I found that the large hammer spur would dig in my side when concealing (carry at about 4 o'clock IWB in homemade kydex). That was the ONLY part that was uncomfortable so i decided to ply my hand at gunsmithing and "bob" a hammer spur. I bought a "new" (used) spur to bob through Numrich. Finally after the summer of carrying the 605 under my t-shirt, i put the "new " spur in (i did not bob it fully, but reduced the spur profile..side note, i will now not bob it fully, i dont feel the spur, and still have a single shot capability). The new spur is NOT a spur with the lock in it. Minor internal differences, but none that would effect (affect? i forget) performance. I replaced, and started to practice for reliability again.
PROBLEM..... my cylinder would not advance right after reloading. only for "first" pull of trigger. all after on cylinder was fine. then i found that it was only on certain cylinders? wWTF is going on??
Finally i got serious about fixng it as i missed carrying the pistol. ( I love the IWB holster i made. very hideable etc) So i spent about 10 minutes trying to diagnose the issue. it seemed if i closed the cylinder "softly" the first pull would loc the rachet. but on second try i was fine... so i lubed and cleaned.. Still nothing.
FINALLY... i realized that the cylinder release was not full going to "closed" psotion with a soft close of the cylinder. SO i removed the thumb release, and noticed all the CRUD i missed cleaning from carrying under my shirt all summer. Yep. the issue with the pistol was MY fault. I removed the built up gunk and lubed the cylinder release. Now.. NO Problems again. I am again carrying this regularly. Just cleaning iit more thoroughly more often.
So that is my experience with 2 Taurus revolvers. No hear say. just my hands on. Personally, if i didnt have a S&W model .36 for a "back up" to my 605 (meaning i use the .36 if my 605 is down), i would probably get a model 85 for a back up.
Has your wife shot the this revolver? Just a thought.
