SAR B6P poly 1/2 A** trigger job ...but it works
« on: December 09, 2014, 03:33:23 PM »
As mentioned in an earlier post, I got a B6P on sale from CDNN for $249 + shipping + FFL fee ...$285 out the door.  The gun shoots great and feels good to the hand.  Using my handy trigger gage, I have about a 12 pound double action and slightly under 6 pound single action.  A nice gun, especially considering the price.



I'm thinking I can improve the trigger pull without spending too much money, so I disassemble the safety and sear cage from the frame.  A rubber band to cock the hammer and keep it that way makes the sear cage that much easier to come out.  Notice the pin just below and to the right of the serial number.....below the number 7.  This holds the hammer housing into the plastic frame/receiver.  You have to drive this one pin out to remove the hammer and housing from the frame.  All other frame pins....leave them alone.



Tools needed for this job.  Small hammer and small punch.  Rubber band, as already mentioned.  Trigger pull gage to measure results.  I used a small hemostat clamp to move spring arm to release the safety from the sear cage and park it in it's release notch, but a small screw driver or dental pick would have worked also. 



Finally, a Wilson Combat spring kit for a S&W revolver.  I had these springs left over from my last Revolver job, so I didn't have to buy any additional springs for the Sarsilmaz.




Here is the sear frame and the hammer frame removed from the receiver. 



Drive the hammer pin out from the hammer frame, and the hammer comes out.  It's under a little spring pressure, so don't let the hammer go flying away.  The spring shown on the left (below) is the stock hammer spring.....16 pounds.  The spring on the right is a trigger return spring from a S&W revolver.  The spring kit for the revolver ships with a 13, 14, and a 15 pound trigger return spring.  I had already used the 14 pound spring on my revolver, so I was left with a 13 and a 15 pound spring to choose for the SAR...I took the 13 pound.  The S&W spring was a little too long, so I clipped a few coils, but since it was only 13 pounds, I left it a little longer than the stock SAR hammer spring.



I reassembled everything with the clipped end of the spring down.  It fit like a glove.  Put it all together to see if it would strike the primers hard enough to give 100% ignition.  I took off to the range.  I used some reloads and some factory WCC NATO ammo.



Every round fired first strike...these are my reloads with standard CCI small pistol primers.  NATO ammo all fired as well:



Now I have an eight pound double action and a three and a half pound single action trigger pull.  I didn't touch anything else.  No polish, no filing no smoothing (and didn't touch the hammer hooks or sear...that's why it's 1/2 trigger job):

I know Wolff makes springs for the Tanfoglio and CZ, not sure that those springs are exact for the Sarsilmaz.  Since Wolff doesn't say they fit the SAR, I decided to experiment with what I had sitting in the drawer.

They should be exactly the same. The mechanics of the SAR are identical to a polymer Witness.

Interesting, nonetheless, but I'd bet you're right on the edge with your primer ignition- I like to keep some 'worst case' ammo on hand for testing hammer springs. I always grab a box of Monarch or Tulammo when I stop by Academy.

Never had a failure to fire with that stuff...but I have guns that have to double strike them. Every single time. Which generally translates to needing the occasional restrike on better ammo.

I always test with tulammo, that way I know it'll run.

Any plans to do the other "half" of the trigger job? Be interesting to see the results.

I'm tempted...but everything I have read suggests once you break thru the case hardening on the hammerhooks, the hammer wears out before 1000 rds.  I don't know how true that is.  I'm not sure if a CGW hammer would fit a poly. 

I have a TZ 75 series 88 that the Israelis did a fantastic trigger job on....2.5 pound single action pull with no creep.  I would love to get the SAR down to that level.

Any advice??

Hi Win, worry not about the case hardening. Unless you intend to really grind away at the surface, light stoning and/or polishing will not adversely effect anything.

I suppose this mod would be similar on the all steel SAR B6 (Hawk) too.

I'd like to know what owner's opinions are of the SAR B6P compact poly!  It seems everyone has problems getting magazines for these critters and I'm interested in knowing if that situation has improved any!  I may have the opportunity to purchase a lightly used one with the stainless slide and want original mags as the rear grip portion would appear ugly without OEM mags!  Has anyone tried XS Big sights on any of these and if so what size?  Does anyone know if outfits like CGW do any work on these?  I'm guessing that some of their springs may work but don't know!
