Hey, whatever floats your boat. The only way to know what youve actually got, is to shoot the snot out of them and see how things go. And thats the same for anything, not just Tisas.
Right now, Ive got around 3000 rounds through the two 9mm guns I have, and 1500 or more of that, was just trying to get the Service model I have to work reliably. Now, I got that as a "used" gun, and Im not really holding that against Tisis, as Im thinking the previous owner might have had something to do with the problems Ive had, but the gun didnt look like it had been shot much before I got it either, so who knows.
If youre just now getting into 1911's, especially guns built to true Series 70 specs, you need to do some homework and understand a few things about them (one being how they load and feed) and why things were done to modify them.
Theres no way I see anyone comparing a Series 70 era or earlier Colt to a Tisas and saying the Tisas was the equivalent or better, especially in the finish department.
If Tisas were to park their GM's, I think you'd probably be pretty close to a GI gun, and with today's steel, maybe even better, but I dont have enough time with the 45 I have to say for sure. It does act like the unmodified GI guns Ive had in the past when you try and feed it different bullet types other than ball. But that goes back to why some things need modified.
And dont take my comments as putting them down or negative either, just things Ive seen and my experiences and comparisons with other 1911's Ive had in the past. So far, I like the Tisas's I have, for the most part, and they seem to be pretty close to the guns I have had good experiences with in the past, but, only time and rounds down range will tell. One thing I will say for them, they sure beat the hell outta Springfield.
Colt, Tisas, whatever, if I were to consider carrying it, it would still have to go in for some basic tweaking before I would. Thats just the nature of the beast.
