Hi guys,

I just bought a used 1995 P226 9mm. I think I got a pretty good deal but may need to switch out some parts (recoil, mainspring, other?).

If I'm going to order parts, I might order some extra but wanted to confirm something first (want to minimize how many different parts I need):

Are parts for my 2007 and 1995 P226 interchangeable? Anything specifically that is not? Also, I understand that there is a new mainspring but not sure what year this change was made; I've also heard that you can easily convert (no machining required) to the new style from the old style. If this is true, is there an change to the trigger pull weight? Reliability (since I think the new mainspring is a few pounds less)?

Thanks.

I also own a 1995 KF P226 and I chose not to replace the mainspring assembly. The original works just fine and I prefer to leave the classic gun in its original configuration. If you do convert to the newer (shorter) mainspring and plastic base, you will need new grips or you will have to modify the old ones. In my opinion, it is not worth the expense. You can buy lighter long mainsprings from Wolff.

Great insights guys -- thanks much.

So if I understand your point correctly:
1) It's pretty straightforward to change to the new mainspring and trigger bar spring, especially if you have the right tools.

2) There is not functional difference but the new mainspring may result in a lighter trigger pull since the old style spring has a higher spring constant.

3) The new style mainspring and trigger bar spring will require the new style plastic grips (or modification of the old ones)

My thinking in considering the new style springs is two-fold:
1) keep just one style of spare parts. But not really a big deal since these parts aren't too expensive.
2) keeping the trigger feel as similar as possible between the two guns.

I actually really like the trigger feel of the KF as-is. It's light and smooth and constant from start to finish. This may sound odd, but I'm not sure I'd want to make it a lighter pull (which may result in going to the new style springs -- but may also be offset since the springs are newer and stiffer).

I'll put this decision on-hold for now until after the 10 day wait is over and can take the gun to the range.

One question: how do you tell if the mainspring / trigger bar spring need to be replaced? Is it gradual failure (occasional light strikes, whatever)? Or more abrupt?

I'm a little torn -- on one hand, I don't want to change anything because it feels perfect as-is. But I get that since I don't know the history, it's safer to replace wear parts now (but it'll probably result in a stiffer trigger pull, right?).

Thanks again guys
