I own 2 STI Trojans,one in .40 and one in 9mm.
I have had the .40 for a couple of years.
It is an absolute pleasure to shoot.
I got a Trojan 9mm last week.
Right out of the box,it ran without a problem,
using my reloads.
A friend of mine also bought a 9mm Trojan two weeks before me
and his was also fine using Winchester factory and my reloads.
After shooting his,I just had to have one too.
Accuracy is very good
I don,t believe there are any MIM parts.
If there were,I wouldn,t really care.
I've put quite a few rounds through the .40
and it just keeps on running.
