A year ago I bought a Tisas Carry and within a couple hundred rounds started having a failure to extract the empty fired case. It would happen randomly every few magazines. I experimented with different mags, different ammo, made sure the gun was clean, removed and tuned the extractor, but it kept happening. Finally installed a Wilson extractor and this MOSTLY fixed the problem but it can still happen if the gun is even a little bit dirty. It happened a couple weeks ago and that was the first time in months and a few hundred rounds. It wasn't sparkling clean but not super dirty either. Maybe a hundred rounds since the last cleaning, if that.
Well recently I bought a second Tisas Carry, because hey they're cheap and I like having spares. Shot it for the first time yesterday. Field stripped and oiled it first, went out to my range, and in the first magazine, yep, a failure to extract the fired case. Ran a second magazine, same thing. I tossed it back in the bag and was done with it for the day.
I probably will eventually get a Wilson extractor for this one too and see how it goes. But I have concluded that the Tisas carry is, for me, wholly unfit for carry and will be strictly a range gun. I have zero confidence in it for personal protection. I've gone back to carrying my first 1911, a Dan Wesson Specialist. It has never given me a single problem. Awesome pistol. Makes me more accurate than I really am.
The Tisas will be a fine range gun and I'll live with the occasional malfunction. It's 9 mil, so it's a good bit cheaper to shoot than 45. I mean, it's a $400 1911. It is what it is.
