Hello. My 9mm Trojan Long Slide is an earlier one and has the flatter front grip strap than the more rounded ones on current guns. The pistol has a one-piece feed ramp and a trigger that I would estimate at about 4-lbs, perhaps a tiny bit less, but it breaks cleanly with no creep.
The pistol has never malfunctioned with +P ammunition, but on occassion the slide will fail to lock back when using standard pressure loads. I think these come with 10 or 11-lb recoil springs (Don't remember for sure), and a friend having the same problem went with a recoil spring 1-lb lighter in his long side and the failure-to-lock-back after the last shot went away.
As I normally shoot warmer loads in this one, my recoil spring was not reduced.
The pistol has never, ever failed to feed, extract, or eject with a wide variety of handloaded JHP's, usually Hornady 124-gr. XTP's loaded to about 1240 to 1260 ft/sec.
To me, felt recoil from any 9mm in a service size pistol is not "bad" at all, but it is very, very reduced in this pistol. When firing quick repeat shots, the sights hardly seem to move in recoil.
Accuracy is superb and well beyond what I can do off-hand in the field. I own a SIG P210, a handgun usually given great honors for accuracy, and it truly is, but whether the STI is as accurate or just easier for me to shoot well, I don't know; I shoot the STI Trojan Long Slide better than I do the P210.
On a good day and from a rest, groups from the Trojan with selected loads
usually go into about 1 1/2". On an average day, they hit about 2 to 2 1/2"; I'm sure it is me.
The chamber is very well supported and I guess if a person wanted to hotrod 9mm, this might be a good choice. I do shoot warmish loads, but nothing in the "nuclear" range.
These 5-shot groups were fired with the STI Trojan at 15 yards. They were done with me seated, with my wrists braced, and in slow fire.
This 25 yard 9-shot group was fired seated, wrists braced, and in slow fire using Winchester USA 115-gr. ball.
This is what my 9mm Trojan is "fed" most of the time. It's a heck of a good small game load and one that's proven accurate in a number of my 9mm pistols.
The "STIppling" or scallop-like cuts on the front slide do offer a bit more purchase than plain steel, but to me not as much as either vertical grooves (ala Gold Cup) or checkering.
