JoseyWalesX Posted January 2, 2012 Share Posted January 2, 2012 I have around 6k rounds through my Pro and was wondering should I go ahead and change out the recoil spring or wait until I start having FTE's. Also, are you guys replacing them with the factory setup or using a different spring and guide rod? Link to comment Share on other sites More sharing options...
mcracco Posted January 3, 2012 Share Posted January 3, 2012 As your recoil spring weakens you would tend to have problems with the gun feeding/returning fully to battery. I have yet to see an 'official' word on recoil spring maintenance but generally replace after 5,000-10,000 cycles is what I hear. I would tend to lean towards 10,000+. The weight spring needed depends on your load and, to an extent, how accomplished of a shooter you are. I needed a 13# spring when I was using a 147gn RN but had to switch back to the factory 16# for 124gn FP loads. The guide rods and springs from SSS are great. Actually their button head screw (S&W uses hex) make reassembly a microsecond faster. Link to comment Share on other sites More sharing options...
saab Posted January 3, 2012 Share Posted January 3, 2012 I asked this question of S&W about the same # of rounds. Well, they sent me a new recoil spring AND a new striker assembly for free! Great service!!! As far as other types of springs, if it ain't broke, don't fix it! Link to comment Share on other sites More sharing options...
