Sorry for being gone so long!! The Taurus is a good gun. Nothing fancy, but serviceable. To make the trigger better there is a couple options. First is a trigger job. . .but you said that is too much sooo. . . You can get a spring kit for it and have it installed. The springs are about 15-20 retail and any good gunsmith shouldn't charge more then another 20 to put them in. Its an easy job. This will make it lighter, but it will still be a little rough.
Cheapest thing to do to get the trigger pull smoother is to get yourself some snap caps. They are dummy rounds that have a spring primer on them so you can dry fire a gun and not hurt the fireing pin. Then you give your trigger finger a real good workout pulling that trigger again and again and again and again!! That will smooth out the surfaces in the action that feel gritty. Its not as good as a trigger job, but it will improve the feel without the cost of taking it to a gunsmith.
I've just recently re-entered the fire owning world, and got my Canadian Purchase and Acquisition License (PAL) for restricted and non-restricted firearms. I had given up my firearm collection in the 1990's, after I lost my hunting partner. My first pistol, with my new PAL, is a Regent 1911 A1 .45 copy (Turkish made). I use to own a Colt 1911 (pre-1926, not an A1), and had that tuned up to hit a 6" square target every time, at 100 meters. I noticed that with the Regent, I was lucky to hit the 100 meter 4" gong twice, out of a 7 round clip (more with one of my 10's), so I designed and built what I call my V-6 bushing compensator (I'm a hobby machinist). I had looked at other designs on the net, then came up with this one myself. Longer on the barrel than the stock bushing, and tighter in the slide, I now hit that 100 meter gong at least 5 of 7. I have another one in my head, with 2 more ports making it a V-8.
Well, right there you have seen the quality difference of good machining and just good enough!!
Thanks for sharing the pic! I love to see what people come up with. And the accuracy improvement you saw was the bushing/comp you made that is tighter. It is now holding the barrel tighter with the slide and sights. Fitting a new bushing for a 1911 is one of the most important things you can do for accuracy! Good job and keep tinkering!
And here is a pic of a 1911 i build a few years ago. A friend of mine was sending pic after pic of custom 1911s to my phone with fancy leather and nice shiny blued slides. So I had to throw my "work" gun up on the table and take a few pics of it to send to him what a real gun looked like. Not some showpiece kept in a glass cabinet and brought out to impress friends!!
