If I were a department armorer, sure. But as a lone end-user who’ll detail strip the gun once every 10k rounds the difference is just not meaningful.
The biggest difference is that Glock’s trigger mechanism isn’t something most people break down into its components so all the little parts and pins in the trigger, the bar itself, the housing, the connector, the trigger spring… they look like one part.
Mine is going to be wearing Lasergrips instead of the E2 grips it came with so that’s eight extra parts! Four grip screws and four washers.
Todd: As someone who has never quite had the courage to detail strip a SIG, let me ask you what the plastic knife is for. Is that a detail-stripping tool, or is that a subtle way of mocking a lot of pistol photographs with their inclusion of pocket knives?
TDA = Traditional Double Action, often called DA/SA (Double Action Single Action).
I like it because the first shot, while a little harder to master, adds a degree of safety both during normal handling and during PID/engagement for the first shot. Then after that heavier, longer first shot you end up with a trigger that’s usually shorter and lighter than you’d get with, say, a stock Glock or M&P for all the rest until you decock to move, holster, etc.
There are trade offs. But the TDA is so maligned by people who don’t understand it or haven’t taken the effort to learn it properly that most of the information you’ll read about it isn’t worth the electricity needed to keep it on your computer screen.
re the spring – in addition to identifying the model of pistol it is appropriate for, it also helps indicate the correct way to put the spring onto the guide rod. Take a close look and you’ll see that the ends of the spring are different. Same for the 226 and 239 also. Formally, the springs only go on one way. I’ve had the spring on back to front and it interfere with the take down lever, preventing it from rotating. That was an interesting learning curve. If it happens to you, the trick is to lock the slide back and manually rotate the guide rod incrementally until the take down lever is clear of the spring end.
I changed the trigger on my 229 to SRT it’s a simple, but very effective modification. Enjoy!
Todd: I see that Bill Riehl is doing the work on your 229 and is describing what he is doing on Pistol-Forum. That is one of the best threads I’ve ever seen on the Internet, and you really ought to link to it here–the lessons it is teacing go far beyond SIGs. (I also think that you are going to end up with a pistol that is better than the best tuned Sigs you can obtain commercially).
Steve — There will be a full accounting of Bill’s efforts in a future blog post. It’s obviously deeply impacting the test since the gun is getting such an incredible amount of post-production TLC and I think folks reading about the test need to know exactly what is being shot.
It’s not an off the shelf SIG by any means now, but the changes have all been well within the production tolerance limits of what you could get straight from the factory (to the best of my knowledge).
It will, in fact, nonetheless be the greatest P229 ever. Until he does my second one in a month or so.
Justin James- The different white on the recoil spring identifies the tighter end of the recoil spring which must be seated on the guide rod. The other end is slightly wider and won’t stay on the guide rod as well.
