Hi guys, the reason I'm asking how long you can expect to last with your original recoil spring assembly is because I now have about 4300 rounds through my stock G20 3rd gen and since this weekend I experienced 3 failures to feed in 120 rounds. The round makes it to the chamber but you need to pull the slide back just a little bit and let go before it can fully chamber. I still have the original OEM recoil spring assembly (17 lbs) in my G20 and while it does still feel quite good, I suppose it may have lost some spring tension after 4300 rounds (of which 90% were real 10mm rounds, in the 600 ft/lbs range). On top of that it was freezing outside today and I was on the open range, this may have put some extra stress on the functioning of the pistol. My ammo was ok (OAL of less than 1.250): 11,5 gr Accurate 7 with 170 gr Fiocchi FMJ and normal LP primer, cases were ok too. I wasn't limbwristing (firm hold) and it occured in the first few rounds when shooting a full magazine. I already have the +10% magazine springs. Pistol was clean too, extractor also. Magazine seems ok too. So the only thing I can think of is that my recoil spring assembly needs to be changed after 4300 rounds. It worked well in normal temperatures, but it seems that the well-used recoil spring combined with freezing temperatures will give you some FTF, at least that is my way of thinking. Do any of you guys have any thoughts on the subject?
