I have four pistols which I want to have the SRT kit installed (3 P229s and 1 P226). Do you have recommendations for a gunsmith in the Suwanee, GA area who could perform this? I have watched the videos for this installation. It does look pretty simple, but I don't trust my eyesight and fat fingers. Thank you in advance!

This is a very easy DIY. I've probably done it 10-15x on SIGs and more recently HKs. Once you've done one classic P-series SIG, the rest are pretty much the same. I vote for DIY.

I have to agree with Rick on this. I have done a couple of mine and not hard to do.

I was a little nervous to do my first SRT install. i watched the video from Sig Guy and it looked pretty straight forward. Took my time on the first one. Not bad only took a few minutes. Now five more later all is good. Double stacks a bit easier than single stacks. Tip: use a Q tip to hold the sear. It’s easier that using a pliers, magnet or kelly clamp.

I'd try to tackle it yourself. As others have said, it's not that hard. I like to use a wooden toothpick to fish through the hole and line everything up, then kind of act as a slave pin for the actual sear pin. As others have said, it's easier on the double stack guns (which all of yours are) because there's more room for your fingers in the magwell. By the time you get to your fourth one you'll be a pro!

If you really don't want to do it yourself, any halfway competent smith or armorer should be able to help you out. Sorry I'm not familiar with your area so I can't make any recommendations. If we weren't halfway across the country apart I'd be happy to help you myself.

I also recommend doing it yourself. If you are not against watching YouTube, there are some good videos that show the whole process. Unhook the leg of the sear spring before doing anything else. A couple of the videos I fast forwarded through don't show that step and doing that first makes it a lot easier. It's difficult at first to get everything lined up but, as noted, a slave pin or punch of some sort will help.

For reseating the sear pivot pin spring, it's useful to get a small flat tip jeweler's screwdriver and Dremel a small notch in the middle of the tip/blade. That will make it easy to grab that spring leg and re-seat/tension it.

Another vote for doing it yourself.
There are numerous videos available that can provide assistance.

Years ago I performed many DAK-to-DA/SA and DA/SA-to-DAK conversions with very little gunsmithing knowledge..
All I had was a Lenny Magill disassembly and reassembly DVD..
It was very interesting to see how the parts of the pistol worked together.
