I bought a Rock Island 40 a couple of years ago first one never made it through a single magazine in almost 100 rounds. I tried Kimber and Wilson Combat magazines as well as the one that came with the pistol. All was with brand new factory ammunition I bought with the pistol no handloads. I cleaned and lubricated the pistol after a couple of magazines when I received it there was lots of some kind of oil but the barrel had copper in it I guess from the test firing. The cleaning and lubricating didn't help. I took it right back to the store and told them to order me another one and get that one fixed or see if they could have it replaced from wherever they got that one from. They got me another complete pistol and sent that one back the new one functions perfectly with four different types of bullets and handloads. I don't know if they credited them for the bad one or what it didn't cost me anything. Rock Island told them break in for this pistol was 500 rounds I think that is BS. My cheap Tisas 1911 45acp has functioned perfectly from the first shot I upgraded the magazines to Wilson and Kimber. Maybe it's the shape of the bullets of the 10mm and the .40 causing the problems or the added recoil.
ОтветитьWonder if this is a recoil spring issue? May need a stronger spring.
ОтветитьBased on your experience what are your suggestions? It seems I got one that is almost as bad as yours. Mine is fairly accurate but requires a tap to chamber rounds much too often. Mine does it with all factory ammo.
ОтветитьI'mma give a bit of advice being I do nothing but tune these mid range 1911's as a side hustle. With cheaper 1911's you may have to tune them, this is expected. You may have to tune the extractor, tune your mags to the gun, Yes, I did say tune the mags TO the gun you plan to use them in or you can install a higher mag catch/tune feed ramp and mags.. Misfeeds are usually mag being too low in the magwell(you need a higher mag catch), you release the slide and the round nose dives into the bottom of the ramp(in this case that would mean your mag isnt presenting the round properly).. or feed ramp needs a polish. It can also be the mags you are using are not presenting to round to the feed ramp in a correct angle(most of the time a pair of taped over pliars could adjust the feed lips to correct this issue). 1911's HIGHLY and I cannot stress this enough, EXTREMELY rely on how the round is presented to the feed ramp. Usually if a higher mag catch wont fix it, or a feed ramp mirror polish...Now that would mean how the mags are presenting rounds is incorrect..I've had Girsan guns where neither higher mag catch or polishing solved it, meaning the feed ramp and mag catch were not cut at the correct angles. I've literally had to tune a set of mags to the gun, mind you this is girsan's 10mm's which are 1/3 the quality of Tisas..The reason you pay so much for a Kimber is due to them assuring all angles are correct, the mag presents the round properly to the feed ramp, extractor tension is to perfection. So with the budget guns, tuning is almost always required. The manufacturer no matter how many times you send it back is NOT going to insure this thing feeds every ammo 100%(which I think you may be expecting). That is your job on these cheaper guns unfortunately. They are gonna inspect it, check extractor tension and run 2 mags of factory OAL FMJ ammo through it and call it good, the rest is up to you...
