Colt is generally a low end 1911. Not quite sure what the point of constant comparison is. TISAS is entry level, meaning among the cheapest 1911s money can buy.
Again, if you like them, that’s what matters. Not quite sure what the point of four of them is, but I’m a quality over quantity guy, who’s fortunate enough to have both.
What’s high end? Wilson Combat, Les Baer, Nighthawk, Guncrafter, Ed Brown, Cabot, ACW, and several others. The high end 1911’s are generally $2500 and way up from there. Superior parts quality, hand fitting and/or precision machining, extreme attention to detail, nicely finished, etc, etc
What parts are superior? You know Tisas also offers hand fitted models?
One of the marvelous features of the 1911 was that pieces parts from one maker could be put into a 1911 from a different maker and still function. The design was not mean to be some showcase doll but rather a tool.
I understand the enjoyment of a hand crafted product and own quite a few fountain pens that were more expensive and took greater hand labor than goes into a Wilson Combat, Les Baer, Nighthawk, Guncrafter, Ed Brown, Cabot or ACW 1911. They are enjoyable and in fact as functional as mass produced fountain pens. And as I said, they did cost a whole bunch more than my mass produced fountain pens.
But my experience with "High End" 1911s has been listening to friends tales of their "High End" 1911s and finding they really don't shoot any better in my hands than my Tisas. Four 1911s can hardly be called quantity, and in fact the differences between the four versions satisfy four different experiences.
One is an example that is very close to what followed my dad home from his four year all expenses paid tour of North Africa, Italy, the Mediterranean Sea and the Middle East. It's complete with the post WWI era sights. A second is similar but just slightly smaller and slightly easier to carry (and I do carry my firearms, every single day). But my eyes are also Operation Torch Mk 1 version 1 eyes and so I also have two 1911s with better sights, one full size and one Commander.
But with well over a thousand rounds through each of them I still have not had anything break, anything that needed tuning or adjusting on the pistols (did have to change out the followers on a couple Wilson Combat magazines) and I can be sure the pistols will function if needed.
So I have some 1911s that have superior parts quality, haven't needed hand fitting, do have precision machining and attention to detail and are nicely finished. And I'll carry them in good holsters and enjoy their functionality.
