I think the stock recoil spring is 19 pounds. They do sell a low pressure and a high spring. For different loads.How's the slide on the I'm compiling a list of carry guns for the wife. She really struggles with the slide on my 19x. She loves the feel and easy slide stop function of the vp9 and struggles less with that slide. The canik looks similar to the vp9 slide stop
I just need to talk her into more old fashions to get the grip strength up ¯\_(ツ)_/¯
