spearogun Posted December 16, 2011 Share Posted December 16, 2011 I have three questions for you guys. I have a M&P Pro 5" with an Apex Comp kit in it. I have been using the gun for IDPA/USPSA and 3 gun. So far I have only been running factory ammo and the gun runs 100%. I really like the gun and I shoot it much better than I did with Glocks. I used to reload for my Glock and I messed with a steel guide rod and different spring weights. The gun was never that reliable for me. I'm going to start reloading again and I'm thinking about using different recoil springs to get the gun running smooth. What weight spring does the M&P come with from the factory? What spring weights are you guys using? What advantages and disadvatages are you guys having with shooting lower power factor ammo and using lighter springs? Thanks Quote Link to comment Share on other sites More sharing options...
