Gomar83 Posted March 14, 2017 Share Posted March 14, 2017 I am shooting a M&P 40 4.25" barrel I was wondering what are the advantages or disadvantages of a none captured round recoil spring (1911 style) to a captured flat coil recoil spring (factory) and a heaver guide rod.

Kurusty Posted March 15, 2017 Share Posted March 15, 2017 I use non captured springs in my M&P's because I reload and I can change from 11-13lbs springs. I find that it helps with the recoil. You can tune them to your liking. I'm sure that you'll find my scientific answers in the 1911 section. Link to comment Share on other sites More sharing options...
EliteGuard Posted March 15, 2017 Share Posted March 15, 2017 You can change recoil springs quickly with a non captured guide rod. You can also buy a heavier guide rod from Speed Shooter Specialties to increase the muzzle weight to help with recoil. As far as downsides, I find it harder to reassemble the pistol using the non captured guide rod. Link to comment Share on other sites More sharing options...

Gomar83 Posted March 16, 2017 Author Share Posted March 16, 2017 has anybody used a Sprinco recoil reducer system on a M&P before? Link to comment Share on other sites More sharing options...
Kurusty Posted March 24, 2017 Share Posted March 24, 2017 any thoughts on spring weight? 180 gr bullet 173 PF?I'm running a Wolff 12# without any issues for 2 years now. I change that and the firing pin spring about every six months. Link to comment Share on other sites More sharing options...
Gomar83 Posted March 24, 2017 Author Share Posted March 24, 2017 Is that a captured spring or none captured spring? Link to comment Share on other sites More sharing options...

Run an 11-13 pound spring of profile and captured status that you find that you like (I bought all 3 and settled on a 13 with my preferred load) and learn to grip the gun with about four times the pressure of your average shooter... and go run several thousand rounds through it without changing anything You'll shoot it pretty well after that.
