To add to this discussion: Since my previous post - a couple weeks after it - when firing the pistol, the barrel broke in the lug area. Called Taurus and they sent a new barrel when they received the broken one (well, it took quite a while - they claimed they were out of stock). Installed new barrel and the pistol would not cycle - the barrel would not fully drop out of the ejection port to allow the slide to continue backward - to fully cycle. Of course, I did not have the original barrel for comparison purposes because it had to be sent back. I called and they offered to send another barrel - same deal - but I preferred to send the pistol back again so I can hopefully get something back that works. It has been there for about a month with no resolution so far.
I have known two people (including me) who have had the TCP. My friend's was problematic from the start and they had to send him a new one once. Mine was reliable for about 3 years (he fired his much more than I did) but it has not been operational since July. It costs about 40$ to return it for warranty service each time. So, sending it twice and a barrel once cost me $90-100 - probably more than I could get for it. Thankfully I do not rely on having this pistol available - it is never my primary carry.
But once it returns or is replaced, it will be traded for whatever I can get for it - likely on the purchase of a G42.
