PWM...... I also saw it at IWA and at many SCI shows.
IWA was where the first production model was sold. The gun continues to gain a following and there are approx 50 rifles being used in the field, with orders on the books.
I believe it was two years ago at an SCI show in Reno that I saw a 375 SxS with stainless barrels and wood fit for royalty!
I cant get over the workmanship and could only imagine having a speciman such as that in my cabninet......

maybe one fine day.....sigh
