Heinie offers one as well. While we are castigating I think Richard had his before Burns
Like Ted said, they are all good and who was first doesn't matter. There are enough variations of a theme that there seems to be plenty of room in the aftermarket 1911 parts market for all of the players. I think that all of the talented people working on 1911s now is the reason that I feel we are at the zenith of custom pistols. I mean, look at all of the work posted here, brilliant.
BTW, I thought Heinie came up with "scallops" as his work was the first I saw featuring it. A few years later I see STI guns coming from the factory scalloped and thought, "Wow. They are biting off of Heinie and not giving credit." Then I read not long ago, where Heinie stated he didn't come up with it and I believe Dave Skinner at STI is who he credits seeing them from first.
Now look at Heinie's scallops versus Chuck Roger's version. I think Chuck's version is more "grippy" because he either goes a little deeper or is spaced slightly less apart, or both. The result is that the intersections of the scallops are closer together giving some "sharper" lines in the design. Scott at SDM does them similar to the way Chuck does.
So I guess I'm just saying that even "new" things with the 1911 have been done by others before too. How many of the names mentioned are variations on Videcki triggers? IIRC Burns stated he brought his to the market because Videcki went out of business. At any rate, aren't all of these parts copies of ones thought up by John Browning?
Sorry for being so verbose, first post of the day, and I also agree with the others, modify the trigger in it. Good luck & enjoy.
