Congratulations in you 21SF. The steel guide rod replaces the factory plastic one and improve the cycling by allowing less torque on the part and makes more durable, the plastic guide rods can chip, crack or break resulting in feeding or ejection failures and guide rod flex can contribute to accuracy problems. I saw a youtube video(4:08 mark) a torture test with a 1,000 rounds, about the last 100 rounds or so the plastic rod melted and spring out the Glock, the pistol continue to shoot without the guide rod and only with the spring.Well I bought the 21 SF from my friend last Sunday. Now I have to waite the 10 period since I live in CA. I am looking forward to the first day on the range. This gun has a steel recoil spring guide assembly along with the factory part also. What advantage does the steel spring guide give you?
Thanks again for all of you input.
I can. I've shot a stock 23 and a highly customized 23 at the same time. Took turns shooting a mag in each. Other than a better trigger on the one, I could not tell the difference. If it were not for the slightly lighter trigger pull on the one with all customized parts in it, I really didn't see much difference in how they shot or felt. So I say that a stainless guide rod is probably more dependable as far as not breaking or chipping or whatever, but it doesn't do much for how the gun shoots or feels.Would you care to elaborate?
Actually, that may be to your benefit. I looked at both the ambi/rail 21SF and what someone called the California model (standard safety and Glock rail). I much preferred the latter and bought one. Lot's of posts about the ambi safety being a problem and the rail mostly makes it harder to find a holster....since I am in cal there is only the one model of sf I can get (thank you DOJ... ;^( ) so ambi and picatinny are also not concerns.
