Ruger P89 guide rod question

On the Ruger P89 , was there a small "nipple" protruding out from where the guide rod meets the barrel lug ? I have an 89 that is flat there in that area. But I ordered another guide rod for the 89 and it has the "nipple". When I assemble it , the guide rod pokes out from the slide.

Earlier pistols had the guide rods with the little nipples on them, but they changed over to the flat ones at some point during production (my P89 was made in 2006, according to the serial number, and it has the flat end rod). I'm not 100% sure, but I think the barrel link and/or lug may have been slightly changed when they went over to the flat one, meaning the rods might not be interchangeable, which seems to be confirmed by the fact that the older style guide rod protrudes out of the front of your pistol. If this is an aluminum rod, it would be easy enough to cut or file off the nipple then polish up the end of the rod and make it work. If it's a stainless one, you could still do so, it would just take a bit more work, given the harder metal. edit: This is assuming that both rods end up the same length. Compare your original rod with the one you just got and see if they're the same length minus the nipple, before you do any chopping or filing.

Another thing to watch for in this area, as long as we're on the subject: The recoil spring is unidirectional. One end is slightly larger in diameter than the other, and this larger end must go toward the muzzle. When I first took my P89 apart I put the recoil spring back on the guide rod backwards and it caused some binding issues. I flipped it around and it worked fine. When you slip the spring back on the rod it should fit snugly. If it slides on easily you probably have it backwards. I don't think this has anything to do with your issue, I just wanted to mention it in case you weren't aware, and save you some hassle.

edit 2: I was browsing the schematics at Gun Parts Corp and they specify a barrel link for the nipple style rod and one for the flat rod, so confirmed, they are different.

don't sweat it ... first time taking my P95 apart and back together I thought I had the extractor plate pushed down BUT IT WASN'T ... put the slide on and the whole thing locked up tighter than anything ... took a guy at my LGS to show me the fix ...

That's great. I'm glad that fixed it for you (even though I didn't think that was the issue ).
