I posted this on another forum a couple years ago. Still, since this is a new forum I thought I would share.
I finally got around to taking pictures of the parts that I replaced and the parts that are stock. First off, if you haven't seen a picture, here it is.
It is a Springfield Armory GI 5" Parkerized. Model # PW9108L. I got it for $420 out the door at a gunshow.
The main thing I didn't like about this gun is the ILS safety in the Main Spring Housing. It has a little key that you use to turn a little nub in the MSH to lock the mainspring cap so the hammer won't cock.
I got out my Brownells cataloge and started writing down the number of the parts that need replace. (Main Spring Cap, Main Spring Retainer Pin, Main Spring, and Plunger) You can see the parts and the difference between the factory SA parts and the Colt parts.
The little 'L' shaped silver piece was another one of my worries. SA suggest that before you take out the MSH you need to cock the hammer and place the little 'L' shaped piece where the Retaining Pin would go. It will keep the Plunger from flying out.
It should like like this.
I would rather have the retaining pin, then I don't have to worry about loosing another tool or part.
