Had a chance to really look one over yesterday and it was very very impressive.  Fit and finish was superb and it felt really good in the hand.
Price is steep but what about performance?

I have a STI 10. Shoots great, very accurate . Workmanship is outstanding.
The gun will clover leaf my 210 gr cast bullet at 1220 fps at 25 yards.I have only shot reloads thru mine and have never had a problem. I took a bobcat at 29 yards with the 210 gr cast bullet, cat was facing me and the bullet went in below the chin and the male dropped at the shot. I also bought 2 extra mags (1-15 rd and 1-17rd).
