Sig 226

Weight and lack of a roll pin for the breechblock.





Of course, it also says "Stainless" on the slide. ;)
 
And it should say stainless on the slide. All P226 has a stainless slide from what I know. Only the coats and finishes differ.
 
The breechblock is what the extractor is in and the firing pin hole is in. It is what the back of the cartridge rests against when a round is chambered. If this is a seperate piece that is pinned in place, you have an old style carbon steel slide. If this is all one piece of metal integral to the slide, then you have a new style stainless slide. A rollpin is a pin that holds the breechblock in place that is made of a rolled up piece of metal similar to rolling up a piece a paper into a cylinder. Opponents of the rollpin argue that over time the rollpin will compress and become loose and sacrifice the integrity of the mating of the breechblock to the slide. I have had no such problem in my Sigs. But if the problem did arise, it is a cinch to fix. I actually prefer the old style to the new style as the new stainless slides are significantly heavier and cause the gun to be top heavy in my hand. Hope this helps!
 
Somewhere between 12,000 and 20,000 rounds, the roll pin frequently starts drifting during extended range sessions. Usually to the left. Push it back in. If it starts drifting too easily, replace it with a shiny, fresh, snug new one.

This is no more of a "fatal design flaw" than, I don't know, say, a swinging link that gets stretched from hot loads? ;)
