As i recall a 5900 series 3rd generation had a 14 lb recoil springs.But if you have ever had the pleasure of looking over or shooting a pro race gun, when you rack the slide you would think that it had a 8 lb spring in it? Wolff and brownells offer springs for 5900 series pistols from 8lbs to 18 lbs .when you shoot steel,or IDPA etc you have to be classified with certain rules ,one being a power factor. So could some one explain this odd relationship.If you run a 8 or10 lb spring and attain a certain power factor one would think you would beat the hell out your frame ,with the slide coming back at warp speed with little to slow the action.A pre thank you for any feedback.Any spelling or grammer errors.Can be atributed to a rotor cuff pain pill.
