I just bought for myself an Iver Johonson longslide ported 1911 in 10 mm and 300 rounds of S&B ammo, Its in the mail.. I can't wait to check it out...

Are they makers the same folks that make Rock Islands?

I figure it is probably not in house and your guess is valid, we will see...

Actually to answer your question, they are not any part of Rock Island in any way. I have pirated the following to answer this question.

"Iver Johnson Arms is a premier importer of 1911 pistols. We have a full line of 1911s in all different sizes, calibers, and finishes. All of our 1911s are Series 70 which means there is no firing pin block like in the Series 80 which can be problematic. Our 1911s come with a flat, serrated, steel mainspring housing to hold up to the rigors of an everyday shooter, and our pistols have a finger relief cut near the trigger guard for a more comfortable shooting experience. Iver Johnson 1911s are manufactured in the Philippines by Shooters Arms Manufacturing. They are made to our specifications and our design, using parts approved by Iver Johnson."

From what I could find, Rock Islands are made by Armscor. Also in the Philippines, but apparently a different company than Shooters Arms Manufacturing.

All very interesting thanks for the info.
