Antoine Posted June 29, 2011 Share Posted June 29, 2011 Okay so on my last IPSC match, I got bumped in open because I did not make the trigger pull. The minimum requirement is 5 lbs and mine did 4 lbs and 5 oz. My M&P is 6 months old and I didn't touch anything. A buddy of mine who have the same gun got also bumped into open. Called Smith & Wesson and there's no fix for it, the gun is made this way. Wolff doesn't offer a stronger hammer spring. What can I do to increase the trigger pull over 5 lbs?!? I have a bug match in July and I don't want to screw that up. Link to comment Share on other sites More sharing options...
CHA-LEE Posted June 29, 2011 Share Posted June 29, 2011 You can take the stock trigger return spring and cut one coil off then bend the next coil down and out so you can hook the new coil onto either the trigger bar or trigger pin. Making the trigger return spring shorter will make it stiffer. So less coils = stiffer spring. Taking one coil off should bring your trigger pull above 5lbs.

Antoine Posted June 29, 2011 Author Share Posted June 29, 2011 Sounds like a plan. Will it be reliable though? Link to comment Share on other sites More sharing options...

Jay870 Posted June 29, 2011 Share Posted June 29, 2011 If you don't want to get into cutting & bending springs you could look at the Apex Tactical "Duty/Carry" spring kit. It includes a stiffer trigger return spring and sear spring and is advertised to increase pull weight by 1.5lbs. Link to comment Share on other sites More sharing options...

Yeah. Look in your USPSA rule book, Appendix D4, item 6. Where it says "Minimum Trigger Pull: No", the IPSC book says " Minimum trigger pull (see Appendix F2) 2.27 kg (5lbs) for first shot" Link to comment Share on other sites More sharing options...
beastfrog Posted June 29, 2011 Share Posted June 29, 2011 S&W makes a Massachusetts specific trigger return spring that will add about 2.1 pounds. The Apex duty TRS will add about 1.5 pounds. Link to comment Share on other sites More sharing options...
Antoine Posted June 29, 2011 Author Share Posted June 29, 2011 Is there any Canadian friendly dealer that I can purchase that item? Because of ITAR, I can't export most of the good stuff. Link to comment Share on other sites More sharing options...

saab Posted June 30, 2011 Share Posted June 30, 2011 My understanding is that the international rules say 5lbs. That rule does not apply to the USA. Link to comment Share on other sites More sharing options...
