I decided to go with the 12 pound mainspring since shoot the pistol in IDPA. Installation Results – Beretta 92 with Langdon Tactical’s “Trigger in a Bag” Langdon Tactical lists the expected trigger pull weights post-install with their corresponding mainspring weight as: Start to finish, installation took me about 45 minutes – and that was including multiple rewinds of the videos. I’d venture to say that Berettas are one of the easier pistols out there to work on. However, watching Ernie’s YouTube installation video and one or two others made installation a breeze. I was a little… anxious, you might say about taking the Beretta all the way apart. I’ll be honest, before the kit showed up, the extend of my gunsmithing skills had been installing Apex Tactical trigger kits into M&Ps and the occasional deep Glock cleaning. (The trigger bar, hammer, hammer strut, and sear come pre-polished and stoned.) (12, 13, & 14 pound are the standards options listed – I went with the 12 pound spring.)
I asked about this on the Beretta forum, and no one apparently had any issues with reliability with D springs. So far, the only other hammer spring I have tried in my 92 is the factory D spring, which is rated at 16 lbs as compared to the standard 20 lb spring that comes with the 92. Doesn't like crappy Russian made steel cased ammo. 100% reliable with all US made primers and ammo. I did this in my 92FS Centurion, made the trigger truly excellent 6 pounds 10 ounce DA and 3 pounds 2 ounce SA pull. Use the 12 pound spring and Elite II hammer option. If you want to go all out drop in a Langdon Tactical "trigger job in a bag". Second put in a Beretta or Wilson Combat steel trigger and trigger spring. There are 2 other things that can smooth and lighten the trigger even more. The 1911 spring will work fine but it's slightly too short and make cause problems as it compresses with long term use. I've had good success with Wolf springs too, just prefer the ones sold by Langdon Tactical or Beretta.
#BERETTA D SPRING WILSON SERIES#
The "D" spring is the one that comes in a D model (DAO) 92 series pistol. I usually suggest a Beretta made "D" spring first then try the 14, 13, or even 12 pound springs. I have 8 92 series pistols all run Beretta "D" springs (16 pound) or Langdon tactical (Wilson Combat) 14 pound springs never a bit of trouble over thousands of rounds.
