This one does have Belsales 45 frame, although the standard frame was a very common option and performed just as well. Later evolutions also switched to the Angry 4-way when one piece 4-ways became reliable and common. The Angry 4-way (named for the response it was expected to evoke from Bud Orr at having his stock 4-way replaced) and frame are still regarded as some of the best available. The one fault I've ever had with evolutions performance is the trigger length, which is basically the stock length. I admit, I am a hotrod type for the most part, and it usually takes me a few minutes to get back into the rhythm of shooting an evolution like this. That’s the big thing about these older evolutions, once you get a rhythm going on them, you can maintain it as long as you want. Its perhaps harder to get the high rate of fire (at least for me), and for a novice to them its easier to short stroke, but in the hands of an experienced player its easily one of the best cockers you can ever shoot. Don't let the "stock" parts fool you, its anything but. Although the Evolution is most famous for its use of stock parts, it needs to be noted that the Evolution made a number of contributions to the cocker scene. Two of the biggest were the evolution style bolt and pull pin, eliminating the ball bearing style pin (almost any cocker user who has used the ball bearing style pins for any length of time can tell stories of loosing the ball bearings or having them stick, just like the detents). The other major innovation was the reverse P block, which has become almost a standard on high end cockers, this was pretty substantial in the days of the blocky back blocks.
I know this one doesn't look like much next to the likes of the Solar System cocker and the Aurora, and in fact is about as plain as you can get. However, unlike a stock cocker, the stock color for an evolution body was gray, not black.
