I don't always think we need them, we just want them.
For the Tactical the clone rod will just add weight and be stainless. Some will like this.
For the Tactical with the skinny rod, you will have a wide range of springs to tailor for loads as some have inidcated. This one wil have a bit of a shallow cup to contain the spring end. Without the cup, it was damn near impossible to get the rod into the bushing. Once the rod is installed the cup is not needed as the rod is controlling the spring, so just a shallow cup will do. There is plenty of room for springs so I can be more generous on some of the dimensions. I am sending out prototypes on Monday that wil help refine dimensions. I have tediously measured and recorded all of the dimensions so if there are any issues I can see exactly what was in use.
For the Service this removes the dual captive assembly and again lets the user play with spring weights. I have a few more prototypes going out Monday too but this one is almost ready to go. I just wish there was a known spring that did not require trimming to fit, but most of the people going for this will not mind trimming a coil or two.
I think that the .45s are already sprung nicely and are not begging for different springs, but being able to tailor the slide speed for reloads or some power extremes will be nice.
