Rack cm9 vs shield 9

[2dawson]

SwampDude,

A stiff recoil spring is needed for a few reasons. First, on these tiny pistols the mass of the slide is significantly less than on a full-size gun, therefore it does not absorb much recoil energy. A stout spring is needed to dampen the recoil and to reduce the speed of the slide as it moves rearward. Second, because the slide is short, and the energy of the slide moving rearward must be absorbed over a shorter travel than on a full-size (long slide) gun, a stiffer spring is needed.

How do other tiny guns get by with weaker springs? A Sig P938 is the same size as my PM9 yet I can rack the slide much easier on the Sig. Obviously I get it done with PM9 but it's sure not easy to safely clear one from the chamber.

I didn't see much difference after the break-in. I love the gun, just don't see why they have to make it so difficult to use.
