Well, I recieved my new uncaptured SS guide rod from BigTaco, (That's some quality work man ) I am skeptical as to the need for it, so Big T offered me a deal, He would send me an uncaptured rod, to test, and I'd post an objective review on it. The first thing I noticed was the weight.... Holding the stock rod with spring, in one hand, and just BT's guide rod in the other, BT's was noticably heavier. Now to get the spring off, easier said than done, but I found the trick to be finding something to rotate into the spring, spreading it at the end, that wasn't too heavy, to let go of, in order to rotate the rod through the spring. For me, a jewlers Philips head screwdriver fit the bill. Just place it in the end of the spring, and rotate it around until it spreads the end of the spring enough to allow you to rotate the guide rod's capture end into the new opening. Once the captured part of the rod is inbetween the first coils of the spring, you just keep rotating the rod all the way out. I'll say this, that spring is a heck of a lot longer than I thought it was. This was really pretty easy, compared to installing the uncaptured guide rod and fully expanded spring into the slide assy. I learned a few new 4 letter words, but with a little patience, I got it done. I was a little worried, at first, because the uncaptured end of the guide rod was so much smaller than the captured end of the stock rod, it looked like there would be a lot of slop in the hole, (in the slide), it goes through, while the slide is racked rearward. But not to worry, the inside diameter of the flat spring holds the rod nicely in place, equidistant from the edges of said hole. I would absolutely go with the captured rod if you are going to purchase one. The ease of installation alone will make it worth any price. If this performs like I think it will, I will buy one. Now to schedule a trip to the range..... hopefully soon, if work permits. Stay tuned.
