| I've taken to carrying a p239 in the last year because it meets the demands of the unconventional carry modes I need to use better than my glock. accurate, reliable gun, but it (or my shooting) would benefit from a trigger job. I've experimented with wolff hammer springs in my weekly range sessions, but I'm leery of light springs in a carry gun. anybody have a source for trigger work? I live in the ass end of nowhere, so I don't have access to any local talent and will have to send it away no matter what. thanks |

I was at my friend's shop the other day (The Weapon Works) in Phoenix, Az. He used to do trigger prototype work for Timney, and is very good at trigger jobs in almost anything. A regular customer there had a SIG P239, and I commented that I was going to get one. He wanted to show off his, which had a trigger job done to it. Single action was typical SIG, light and crisp, but was lightened up a tad. The real surprise was the DA pull. It was unbelieveably light and smooth. I would guess it was in the neighborhood of 8 lbs. When I asked my gunsmith friend what he did, he said he just worked over the factory parts, and did nothing to the springs. I was amazed. Anyway, I have no idea if he accepts work from out of town. You can try him. His name is Tom Rajec, and his number is (602) 995-3010. He does have an FFL, so he can accept guns. Outside of that, I picked up a SIG P226 done by Novaks a long time ago. It was very nice, also. |
| Factory weight hammer spring is 18lbs. For the 239 Wolff makes 12, 14, 16lb hammer springs. I used a 14lb hammer spring in my wifes 239. I also used a RP sear spring and did the trigger job myself. The 4lb lighter spring and RP sear springs by themselves will get the DA pull down to roughly 8.25lbs and the SA right around 4-4.5lbs on a 239. I've put 400 rounds from Federal, Winchester and CCI through this pistol after the work and it's been 100% reliable. On my other SIGs (220, 220ST, 225) I use 18lbs with are also 4lbs lighter than factory specs. This is what weight the older DAO SIGs used for a hammer spring according to Ernest Langdon who did the trigger work on my 220 that I used for carry. |
Here's some work you can do on a SIGs sear to smooth and lighten the DA pull quite a bit. I got the info from the SIG Forums and it works great. I don't mess with the SA notch on the sear nor the hammer though as it's VERY EASY to make a SIG have hammer follow, it won't go auto but it'll be decocking itself. The hammer spring & RP sear spring will get the SA pull down to 4lbs which is light enough in my book.   B is usually the sloppiest finish from the factory. Major striations across the face. polish/hone these off. As mentioned before, If you can't run a stone in a straight line, don't try this. Its not technically difficult, but it does require some fine motor skills. C is usually better than B. This also reduces engagement and I leave the depth alone except in extreme cases. I don't mess with this AT ALL, if you mess up the the sear is $30 A, the transition between B and C is where you remove the double action stacking - that point 2/3 of the way through the trigger stroke where the felt pull increases. Decrease the height of this cam, blending it smoothly between B and C D will affect your single action smoothness. Most sigs dopn't require much or anything here. It also requires stones ground in such a manner as reach this tight space. I don't mess with this AT ALL, if you mess up the hammers are $60 |
Contact Bruce Gray on the SIG forum. His screenname is Grayguns. He can shorten the reset. It's a very time consuming endeavor. |
Thanks for the effort gotm4... The armorer (Chris Orndorf) on SIGforum mentioned Bruce Gray, also. Bruce commented back the following: Chris, Thanks for the mention! Did you make the Shot Show? I didn't see you, but I had to leave unexpectedly after only two days. (Trouble at the PD) Please email me. I have some stuff I'd like you to look at. You're right, Chris, Grayguns Inc. does not offer our short reset conversion for carry weapons at this time. While this system totally preserves internal / mechanical safety values and has now been tested for 18 months by team SIGARMS in IPSC competition, we're still not quite there with the concept of this for street use. This is due to philosophy, and not purely for reliability or safety concerns per se. My personal feeling is that reset in and of itself isn't an issue for stock weight SA pulls so long as the operator is trained on this pistol. Short reset is really of great benefit to serious competitors with the skill to exploit the extra "time on trigger" per shot that it yields. Some shooters have developed strong reset habits with other pistols, and will short-stroke (fail to reset) their SIG in rapid fire. For them, and indeed for extra insurance against trigger stall for anyone, the short reset might make sense. We're working on design and testing of our new SR safety levers. Maybe we'll prove them to our complete satisfaction for this application, but for now we're making them for our competitive friends only. Thanks for indulging the explanation! -Bruce |
