I have the srts in my duo tone 75 compact, which I recently acquired, and find the srts terrific.
I own a 75 shadow and an sp 01 shadow. They are wonderful guns, my favorite semi auto pistols. When the chance came up to trade a walther for the compact, I jumped. However, stock, it paled in comparison to my shadows. The long, gritty, heavy trigger and poor sights made it difficult to shoot accurately.
Thus, I sent the compact to stuart for some work. I wanted a poor man's pro tek with a shadow trigger. Initially, I asked for a comp hammer, trigger job, springs, extended fp, fpb removed, steel guide rod, and some decent night sights. When I found out about the srts, I asked that it be installed too. I got the compact back a few weeks ago and have put 3-400 rounds of everything through it.
It shoots beautifully. I couldn't be happier. The long SA reset on the shadows is about the only thing I don't like about them. I'm not great at riding the sear and I have a tendency to slap at the trigger a bit when pushing the pace. The compact now has a trigger pretty close to a good 1911 when shooting SA. The trigger resets to just a bit forward of the release point.
I'm going to send my shadows to get the srts installed pretty soon. I'll send them in one at a time so I always have one to shoot.
